So I've only used this pressure washer one time. kzfaq.infoUgkxfQauTxLT0JLSvqkq10rD79TU4k0Vz8zP The one time I used it, it worked great. I recently had new siding installed but kept the old gutters and small areas surrounding my house that weren't replaced so they looked horrible and dirty because of the new siding. I needed to get it cleaned asap. When I used the pressure washer, man it just melted all the dirt and grime that was on those areas of my house. I used that krud kutter soap and it was over after that. Easy to assemble, feels durable, very simple to use. Also, I purchased a used one to save money and there was absolutely nothing wrong with it. I want to get more use out of it so I think I'll be washing the cars and update this comment as time goes on.

Wet and forget has worked best for me. Spray in spring and then again in the autumn. Not an instant cleaner but give it time and be patient and the stuff works

I worked for a farmer who had a flag stone patio that was many years old but still looked like new. He told me he used washing powder and just scrubbed it with a hard brush. I tried that and it worked a treat. It's also really good at getting oil off engines. I used it on some garage fule pumps I once had to clean. Again. Looked like new and smelt nice on the forecourt 👍 And no harmful chemicals to worry about. Also white vinager is great for getting stubborn stains off stones

Great and much-needed test. I have a load of this stuff and I'm not surprised it doesn't work. Whatever it kills stays there and whatever can't be killed, stays there too.

As a professional landscaper I’ve had to clean some seriously stained patios in my time with lichen (black spots) being the toughest to remove since pressure washing alone might remove most of the stain but won’t kill the fungus so will grow back. What works best in my experience is sodium hypochlorite in the the 20litre drums you get from agricultural suppliers. Brush the patio first and dilute 1 part hypochlorite to 3 parts water in a watering can and use the watering can to cover the patio evenly. Leave for 5 mins then scrub over with a stiff yard brush and leave for another 10 to 15 mins and then pressure wash it off. If it’s a large patio or a hot day do 1 section each time it’s important to not let the diluted hypochlorite dry before pressure washing. After pressure washing rinse again with a hose pipe and flood any areas where the hypochlorite has run off onto grass. Be Carefull as it is strong stuff try not to breathe it in and it will bleach any clothing so wear old clothes and wellingtons. It also works well on the red fungus on roughcast walls using a sprayer. Also I’ve noticed that the hypochlorite once opened weakens over time so if you’ve got old stuff that’s been sitting in the shed for years it won’t work as well.

That rust stain at 11:20 can be removed by using fallout remover from any car accessory store. Its's the stuff you normally use to clean wheels etc (turns purple as it dissolves rust etc).

Good, honest product comparison. Thank you. Back to the tried and true pressure washer system 👍

I’ve been pressure washing for but this year I used patio cleaner put on with a yard brush left it for a couple of hours them pressure washed. The results were the best I’ve ever had!

Yes Stuart, pressure washer all the time. I sometimes soak with just soapy water before pressure washing. Works all the time. Never found so called patio cleaners to work. And of course using the pressure washer is therapeutic 😊😊

We have just tried a product called Proclean, Ultimate Black Spot Destroyer and it is extremely impressive. Sprayed it on with a similar sprayer to yours and immediately it starts to fizz. Within a few minutes the colour of the Indian sandstone slabs started to reappear. It says leave for between 2 and 4 hours an then hose off but I actually used a pressure washer with the fan nozzle we use for cleaning the cars. The results were amazing having thought we'd never seen the colours again like it was when first laid the slabs thats despite pressure washing the patio sometimes twice a year. Its not cheap at £42-00 for two 5 litre cans but well with it.

Great video Stuart and I, like yourself and everyone else, want a spray and walk away solution to my drive and patio, but a pressure washer is the only solution that works. The downsides are the amount of water it puts down in a large area, the messy splashback and clean up and the pointing it can remove. However, there is no alternative, the patio cleaners are so mild now compared to years ago that they just don’t enable them to clean the slabs/block paving.

A great experiment, well conducted. Thsnks!

thank you for the logical, clear and fair analysis!

20 yrs I’ve cleaned many patios, block paving, roofs. If you’re jetting you know it blows out the kiln dried on block paving, a right mess. I just bought sodium hypochlorite for the first time, from Amazon, 15%, 10L tub. I wore shorts and t-shirt, gloves, shades and a baseball cap. I poured it neat onto pavers and brushed in, left it 20 mins and washed off (away from grass obviously) looks like new. No hassle, no hundreds of litres of water, no extra mess from jetting. I then poured it into an empty “Wet and forget” sniper tub, you attach hose to it and you can chose the driveway spray nozzle or the sniper jet to spray on roof, I soaked my lawn in water, sprayed roof, (rinsed my arms and legs as I went just incase any splash back) I then reloaded tub with some “wet and forget” and applied it afterwards. My neighbour had her roof done by those cash in the hand folks, hypo and jetted, looks good but very hard clean, but mines is just as clean but more natural looking, not strip bleached. Anyway I’m blabbing on, all il say is hypo is far quicker than jetting. Absolutely stress free. Just be extremely careful working with it. I had a few pink spots on T-shirt, zero skin burns, obviously diluted through the hose thing I used. Jetting takes hours and so much water it’s insane. Concrete slabs take longer than stone to jet. Look up “wet and forget” on Amazon, but the pink sniper tub stuff to attach hose to, once used, fill with hypo. Great for roof. Slabs I’d suggest 15% hypo, honestly 20 mins and you’re done. Wear PPE, especially on eyes.

A great vid. Many thanks for testing. I've got a karcher 7 with the whirly nozzle, agree that it leaves spirals, I also find that it will remove masonry if you're not careful and is brutal on a tarmac drive!

I used patio magic on my render which had some green patches to clean it up before painting & was pleased with it, I think I went in with 2:1 & worked it in with a paint brush, but it didnt touch anything on my patio (even when worked in with a paint brush as I was using what was leftover from doing the walls) so I'm with you for using a pressure washer on that

Thanks for this! I was hoping at the start that I hadn't wasted a Saturday, a couple of weeks ago, pressure washing a large area of paviors which hadn't been done for years and years. I didn't! 🤣🤣

How refreshing to have a honest opinion.. We done thank you.. 👍

Thanks for this Stuart, I appreciate your sense of humour, who thought patio cleaning could be so entertaining ! I don't think you were really surprised by the results of this test, people are still recommending chemicals and I can see they may help both before and after jet washing but they will not make it clean ! I don't know myself but could something like Thompson's water seal (or similar) help with very porous surfaces like your sandstone ! I think generally we worry too much about cleaning the surface completely, as long as there is no slippery algae and moss, the odd bit of lichen adds character and does no harm ! Jet washing is very satisfying though !

Great video, watched a couple of your vids very well shot informative thanks 👍🏻

I find the chemical cleaner works over months and repeated applications every 6months keeps my drive looking great. Yes pressure washing is great but it blasts the pointing out and eventually takes the surface off mono blocks and slabs. I treated the tiles on my roof too and it looks brand new now.

Wet and forget is the best Stuart I use it each year it even works brilliant on my boat as well ie the canvas roof. Try it when you can. Great video as always

I have had extensive experience of using patio cleaners and pressure washers on patios. My findings are that patio cleaners take 3-6 months to make a visual difference. But once they work they keep the patio clean for up to 2 years. So what I do is to use the pressure washer to bring the patio back to 'as new'. Then a watering to soak the now clean stones with patio cleaner. The patio then stays clean for a long time.

Another informative video. Thanks. I have always used the pressure washer and will be doing my patio again in a couple of weeks. I avoid chemicals whenever possible. You know what I have found works for clearing the algae - plain household vinegar. Just spray it on. A lot cheaper than chemical products. Add some dishwashing detergent and it's also great for cleaning just about anything else, shower tiles, glass, mirrors etc.

Thanks for this Stuart. I've long wondered if these chemical 'cleaners' are any good, but experience has suggested that anything that promises to be effortless is just snake oil! So I've just used the pressure washer instead. As you say, it's quite laborious work but the results are much quicker and more satisfying. For something that only needs doing once or twice a year, that's worth the effort imo. I also pre-wet the patio with the garden hose just to help lift the dirt a little beforehand. ps. @15:18 the label on the Jeyes clearly shows that it is supposed to remove 'dirt', which one would assume makes the patio look cleaner too.

Terrific test!! Thanks!

Cheers Stuart. I used patio magic and was underwhelmed. I use diluted bleach and a hard broom. Leave for 20 mins and rinse. Works a treat on my Indian sandstone but quite hard work.

Brilliant review, thanks very much

Thanks for the video, much appreciated for your time.

We use ‘Wet and Forget’ which I think was the original of these types of products and it performs very well. The instructions on that state it needs rain after the initial 4 days to help it work. It’s ideal for older more fragile surfaces. It also states it can take months and not days to see the best results. Slow but sure 😊

Oh dear Stuart, many of us have learned this lesson for ourselves. Just like you, I have Indian sandstone slabs which look fabulous when clean, and I noticed you have a number of slabs with the tell tale black spots indicating Lichen growth. A pressure washer alone cant eradicate this problem (sometimes it makes the problem worse). After some research online I followed advice that said to use SODIUM HYPERCHLORITE aka swimming pool cleaner which is essentially a strong bleach at 14%-19%. cleans the slabs a treat and removes all trace of algae and Lichen. I now follow this process annually in spring with a 'maintenance spray of a patio cleaner mid season for the best of both worlds. Hope this helps you and other followers.

great guide. many thanks.

I've used spray and walk away. It's great for mould and lichen, but it can take weeks to work (like wet and forget, probably a better product), although algae disappears pretty quickly. It removed mould that pressure washing simply didn't touch. Also useful on tarmac, so you don't pressure wash the top surface into oblivion!

Hi Stuart, well done again, another fascinating and very interesting, informative recording. I always thought a lot of these products are gimmicks and DO NOT DO exactly what they say on the box!! Please keep them coming. Cheers

Hey Stuart. After using the pressure washer you can use a coating on the patio. This keeps the tiles longer clean. The coating is not cheap, but you don't have to pressure wash the patio every year.

Hi Stuart, I use the pressure washer first, then apply an acid based chemical to kill off any mold/blackspots etc. I also do this treatment on my decking before oiling.

Informative, authorative, balanced and well delivered with a rye sense of humour. Great viewing. As you say, for the best results use the algae remover and then blas it with the Karcher!

Great video which has confirmed the way I do mine is perhaps best. Each late march/early April I presdure wash my patio, then after it dries I pour patio magic all over. The pressure washing gets rid of the dirt and algae, the patio magic brightens the patio over time and helps to keep the algae from coming back for the rest of the year. I only pressure wash once a year. Without using the patio magic it's significantly harder to get the patio clean come april. I've also found that aldi sell a patio magic equivalent for far cheaper which is just as good

Great experiment method

Informative video - cheers for this!👍

Hi. I have to agree that the chemicals on their own do not clean properly. I have found that they have to be used with a pressure washer to get the patio really clean. I have now switched to a rotating brush attachment to the pressure cleaner and this has reduced the time spent on cleaning the patio. Great video…I have learned so much from your videos…thanks so much

Thanks for another great video Stuart. The biggest time saver I've come across is the T-Racer attachment to the pressure washer. Seems to give all the benefits of pressure washing in less than half the time.

I think this is basically a win for using the pressure washer a couple of times a year and less poisonous chemicals into the air/water table. Trying to minimise the number of chemicals used in my garden and be comfortable with 'less than perfection'!

Great video again mate and exactly what i was after! Been wondering whether to get Patio Magic for years, but your video has certainly changed my mind! I'll stick to the pressure washer. Great content as always - keep it up!!

Pressure washer is best for cleaning. A few points some of which you may have made in the PW video. Need to take care you do not wash the grout out, wash across not along the grout. With pressure washers you need somewhere to swill (or manage) the dirt you have just released- especially for very dirty paving. Also there is a tendency to slash surrounding items with the dirtied water so rinsing them is also often needed. The "foam" that you washed off is probably the long term protection provided by the chemicals. Perhaps it is best to wash and then apply the chemicals. Then the troublesome areas should stay free of algae until the next clean is required.

Thank you so much. With so many products on the market you always wonder which is the best to use -especially re the cost. Like you I found I needed to pressure wash first but then used the chemicals afterwards and half way through the year to prevent a shaded area turning green again.

What people do is apply algae, lichen and moss removal chemical and then, after a few days, pressure wash to remove dirt.

Hi Stuart, I would never of doubted the power of the jet washer, but would you use any of the cleaners as a preventative for the algae after jet washing? Cheers 👍

I use a scrubbing brush, patio brush, elbow grease and collected water from washing up/showering. Looks great and gives me a workout too.

Nice video. I use both as I don’t think it’s an either/or solution. Patio magic for 7 days to kill any algae, followed by pressure washer to clear the dirt.

My patio is the local “High Street” for about 5 neighbourhood cats so I rather think chemicals are not suitable. Fortunately our problem seems to be moss rather than mold, but it is going to be so satisfying to get it cleaned up! Thanks, though for taking one for the team on this dilemma.

Thanks for saving me time and money Stu! 🙂

I've got the same pressure washer as you Stuart and I have the big round head accessory ideally suited to patios as you don't get spray going everywhere, it works really well and I think uses less water to boot!

Another excellent video. Thank you for sharing this information. God bless 🙏

I was introduced to hypochlorite sodium last year and it immediately made years of dirt and weed residue lift from some stubborn slabs. Now use it in 5 or 6 to 1 as a general weed killer for the drive and patio on very dry days.

Very helpful!

Great video, thanks

Many thanks for your videos - style and content. Glad you did this as I was thinking of trying one of these products. Have you also thought about testing Black Spot removal stuff? Prices vary so much.

Really enjoy and appreciate all your helpful videos. You are a fountain of great information, and a terrific presenter. So here's one for you: please do yourself a huge favor and get a surface cleaner attachment for your pressure washer. You'll be amazed at how well they work and all the time they save. A real joy to operate, and not very expensive. Best regards!!

I recently did my driveway using the karcher specific cleaner in low pressure mode (no lance head and a Syphon tube) and then agitated with a combo of a broom and the t-racer... Finished off going downhill with a standard head... Couple of hours work granted.... But what a result

I bloody love powerwashing the patio! It's like cheap therapy!

patio magic always takes few weeks to work for me including a couple of rainy days with amazing results jet wash is fine but if you use it on concrete slabs or paths it tends to erode surface after a couple of years not had any eroding from patio magic

Totally agree with your results...pressure washer is the way to CLEAN LIKE NEW. I use a Karcher K7 on my "light beige" ceramic patio tiles and it gets rid of all the green algae and ingrained dirt bringing them up like new. Another thing pressure washing does is get rid of any grass/weeds between patio slabs . Thumbs up for your video .

Thank you for your video I got a lot of idea thank you very much😊

I have tried most things and now I pressure wash then spray some sort of anti fungus the cheaper the better because next year I do it again again again again. I enjoyed your vid.

To be honest, I would rather use a pressure washer anyway, because it's not adding who knows what chemicals to the garden environment. Great review though, The results are pretty conclusive. my Concrete pathway needs a good clean, and I am planning to use a hard bristle yard brush and my son's energy, as I am now retired and just delegate- except when it comes to cooking the BBQ! which is where I am off to now with a beer! Cheers Stuart!

I use these twice a year over the winter period, just makes pressure washing in spring much easier as no deep levels of algae etc. The spray and walk away can be bought in pure form so you dilute yourself which is much better.

I wonder if these would be effective after a jetwash as a preventative measure. Next video suggestion; after a spray clean, spray some of the slabs with the chemicals and monitor if algae growth is delayed for longer. 😊

I've been through several cleaning options and my conclusions are: 1 instead of those expensive products just use bleach (same results but way cheaper). And 2, for deep clean patios, the pressure washer is best but I use an accessory (patio cleaner head) that covers a wider area making it a breeze in comparison to the normal pointing thing.

Very fair comparison.

Hi sir I agree your method is definitely the best , especially when you have grass adjacent to the patio . And as you showed you need a mechanical action to physical push the dirt off the surface . There must be hundreds of people who buy these products , and think they will wake up to a new looking patio only to be sadly disappointed . Best wishes as always. 😀👍👍👍

Just done mine, used both.

Useful video. Wellies and waterproof trousers are a must though of doing a large are otherwise your bottom half gets soaked after an hour or so. Canary suits or cycling trousers are cheap enough.

I wish you’d published your video two weeks before you did, Stuart!😊 Then I could’ve saved the 15 quid I spent on PatioMagic. Like you, I followed the instructions to get the mix right and waited for the right conditions and sprayed 3 test slabs. Over a week later there was no discernible difference between the treated and untreated slabs. So, I got the pressure washer out and now I have a bright and clean looking patio. FYI and IMO - pressure washing is so much more satisfying than spraying chemicals.

Wet & Forget is great, you just have to be patient. It takes a while before you notice the difference, but it has transformed my block paving. I use it a couple of times a year. Block Blitz is quite good too.

Great video. I have jet washed my patio but blasted some of the grout out. I'm unsure of the pointing mix to use to "fill" in the gaps?

Thanks for saving me money, I thought what a great idea I have always used a pressure washer. Was a big disappointment when they still looked dull. I`ll stick with using the pressure washer and then spraying with a Path & Patio sealer which I find keeps it looking cleaner for longer...

Glad to see I have been doing it right. I would recommend using a cheap mould spray from a £1 shop/ Home Bargains as a quick fix on a small area. Our back door step gets a little green and slippy over winter. Rather than get the pressure washer set up a few seconds with the spray kills off the slime.

Thanks so much for posting this. I have the same patio (kandla grey Indian sandstone) and I have been planning to do the patio with a patio cleaner as with a pressure washer on its own doesn't seem to do the job. So, I'll be buying the patio magic and giving it a go, looking forward to the results. Thanks again 👍

Here in Cornwall we still have an hosepipe ban so no chance of pressure washing! I successfully used a competing product from Spear and Jackson to remove algae from decking, wood cladding and patio. But that’s all it does - I agree that cleaning beyond that is minimal.

I’ve used Patio Magic for the last 5 years and have always been happy. No quick fix but over the weeks, I think it reacts with the sun and does come good in the end.

Great video. Just goes to prove that there is never really ever a quick and easy way to do these types of jobs - can't beat the pressure washer! Upside is that you also get instant visual gratification too!

I have used both methods and several of the chemicals for years now and my preference is Patio Magic especial if used on concrete blocks. Jet washing will clean but it won’t last any where as long and will increase the erosion of any grout or concrete. The trick with patio magic is to put it on at a 4:1 ratio then leave it for at least a month. Then when it’s had some rain have a look at the difference between what you have jet washed and where the patio magic has been. It’s also excellent for cleaning algae etc off UPVC conservatory’s. If you are going to jet was I would recommend using the T-racer attachment as it speeds the job up and help stop the dirt from going everywhere. Do try patio magic again but have patience.

I'd have been interested to see if the application of the product made the jetting of the patio areas any easier than without. Also, I have an area of Cotswold Stone gravel which brightens up a treat following application of Patio Magic. Off topic now. Could you do a video showing replacing the outside handle with a blanking plate on the french doors. I didn't need to use them as a primary way of entering the house and they would always be opened from inside.

Wet and Forget is brilliant. Rather than pressure washing 4-5 times a year, I now do it once at the beginning of Spring and at the end of October. After the Spring clean the patio stays clean of algae/moss for 6 months.

Like the video. What have you used in the joints, they look so secure and not getting blown away by the pressure washer.Many thanks.

Great video once again, what grout have you used on the patio and how long as it been finished ??? Would you recommend what you used or would you use something else if you had too

I use a mixture of water and bleach - approx 65/35 (more bleach than water). Works a treat and is MUCH cheaper than any 'dedicated' expensive stuff saying "Patio Cleaner" on the label 😮

A very interesting exercise.

Patio magic worked for me. Diluted it in a watering can, gently applied and brushed in with a garden brush. Took 24 hours and all green was gone. Our slabs are quite new so maybe with age the dirt becomes more engrained.

Totally agree you can’t beat using a pressure washer for that newly laid look again, although the only down side I have found is that each time you do this it must remove some martial & I found the algae had an easier time of growing back!

Good video thanks. I have found the pressure washer method the best. I have used a chemical sealer which I would recommend. Just a spray on and leave it to dry. Made cleaning the slabs less often.

I just used the "karcher k5" with the "dirt blaster lance" with the "karcher splash guard" and job done in one go, No chemicals, no extra costs, no splashed up dirt everywhere, no wet clothes! 🤷🏻‍♂️

We use Patio Magic,and have found it very good. Gets rid of the algea, easy,twice a year,great stuff.

Looks like you hit the jackpot with this video...

Very useful - you have just saved me a few quid! I have several sections of herringbone brickwork (one is 80x15 ft!) and I guess a re-mortgage might have been in order. I'll stick to the pressure washer and a couple of days off work instead eh?!

Excellent video. A few points to consider: 1) Did you follow instructions completely? i.e. is it just spray and wash or is scrubbing required with a stiff brush? 2) Does it depend upon the type of patio as to what the results are? Thanks!

Thanks Stuart, this is indeed a genuine comparative exercise of how the competing products work in practice and comes across as a fair assessment of results - very helpful. Thanks.

Just cleaned my patio, tried the patio head cleaner with the jet washer which was fine to start but then it stopped turning round so just used the normal nozzle, worked well. With pets and lots of wildlife in the garden I’d never use chemicals.

Tried the Patio Magic on concrete tiles. It did help and appeared to keep it clear longer when compared to a section where I used diluted bleach.
