Oh yes bottom to top I get those comments every video your explanation is spot on Doctor snowfoamburger missing my best mate I’ve got the Waxstock blues 😢😢

Watching snowfoam videos at 7.40am.... something wrong with me 😂

Completely agree with this method of applying and rinsing, and well explained too. I can tell you that this does make a difference for me. In the winter time my car doesn't get too many hand washes, and will mostly get a citrus / pre wash, with foam straight over the top of that, and then rinse off. Before, when I rinsed from top to bottom, there would definitely be less dirt removed than when I rinse from bottom to top, because it's more methodical and for me it means I don't miss bits that I would if I were just rinsing off the foam, as opposed removing dirt from the car. Wet or dry to begin with? Seen some fair old arguments about this on DW, I do both as I see fit, and again, there are cases for both. If you have some thick mud on the car for example, no point foaming onto that the foam can only clean what it touches, and won't necessarily penetrate through thick mud. I don't really follow the argument that the foam is further diluted when applied to a rinsed car, because I find that a rinsed car which was really dirty, will actually start drying fairly quickly on those still dirty areas - mostly around the lower regions, and any of the now cleaner areas don't matter if the foam is further diluted by a fraction of a percent. I also don't really follow the argument that you are scratching the paint by pre rinsing, I have seen people claim that you are literally blasting dirt into the paint at thousands of psi, when the truth is that there is nothing like that amount of pressure hitting the panels, if you are keeping the right distance from the paint. Getting my own lab coat on here but......those talked about "thousands of psi" are what is inside the pressure washer, many industry experts will tell you that there is actually no pressure when it leaves the gun, and that it is now velocity rather than pressure. Of course, you could argue that it reverts to pressure when it hits something, such as your car, but that pressure is greatly reduced by then.

Just on the note of wet or dry car application for snow foam. I think you're right. It doesn't matter too much. What I find makes the biggest difference is the protection on the car. If the car is, say, ceramic coated and not too dirty, I would foam first. If it's a car with zero protection and covered in mud, I would rinse first, then foam. Just my 2 bobs worth lol. Great video 👍

Another great video Dr McSpecky. Some more really good geeky insight on the joys of snow foaming. I have tried both with and pre rinsing and still not decided which is best as not sure it made that much difference and it goes against the grain not washing of the loose dirt first. Now I have a few different snowfoams after waxstock it’s time to play.

Love the information and good job on your production as well! I'm ALMOST convinced about your bottom-up rinse practice! Lol

I've seen Alan from AM Details' video demonstrating that bottom-up method of rinsing, but couldn't quite get my head around why he did it that way, apart from being able to have a better idea of how far you'd already gone, in the event your progress was interrupted. Now I get it! Makes perfect sense! Great video!

Watching detail videos for over 10 years now, this is a great inside about foaming.

This was very interesting and spot on. I have lost count the number of KZfaq presentations that I have seen where they just gestimate the amount of product to employ, whether it is snow foam, wash shampoo, compound, polish or scratch remover, etc. then they criticise the product or claim that it has limitations against what the manufacturers claims are. It is just the same as those who buy a flat pack, put it together without reading the instructions and wonder why it hasn't turned out as expected. In relation to whether you rinse from the bottom or rinse from the top first. I hear the logic and views of different people. However, I don't see anyone making a tissue wipe test to demonstrate which method removes the most dirt or is the most effective. My view is if you are happy with your routine and it gets the result you wanted. Then that is fine don't listen to the critics, unless they can demonstrate that their way is better than the viewers. I completely agree with you, it depends on what dirt you are tackling light road film, versus mud splash and lumps. I agree what you say that it is personal preference regarding pre-rinsing. Some argue that dirt is different according to location, time of year, time of day, type of driving, now concentrated the dirt is, etc. I have lost count how many times I have heard this argument, but what I seldom hear is what tests were carried out by the product manufacturer! when testing their product. I do wonder when I see a contact wash product used as a contactless foam and then compared to a contactless foam, to then conclude that the contactless foam is better! First thing I consider is what the product manufacturer advise for the best result. Then from my own findings what works best. This was a really interesting presentation and brilliant take on how to approach product use, I loved it, and you speak many a true word.

Love these deep dives!

This video was very simple and straight forward and full of info in more ways than one. If i can sum it up, this one is a very good basis if your wondering on how to wash ur vehicle properly whether ur a detailer or an enthusiast. Well done@

Dr Beaker McSporran , quality as ever and this is the kinda thing thats never spoken about often so idiots like me just plod on maybe doing it wrong . Dilution , for me using a foamer , it can vary the results . Some brands require far more than required on a lance to get more than dish water thickness foam that just rolls off the panels without really gripping the panels at all and thus removing nowt . Removal of foam is where I feck up more , given how far the car is from my home , think Ive shown you before , Id need a 90 ft plus hose pipe and power lead thus Im rinsing it down using a watering can . If its REALLY dirty and baked in mud etc , Id take it the local BP and foam it there and blast off using their lance . Ive been told to NOT bring buckets etc if its busy as Im hogging a bay and not paying so mostly rinse it off , and 1/4 of a mile home and use the buckets there . Not ideal , but my car rarely gets so dirty it needs this , wife n sons often are different

Great video specky. Top bravery marks for standing outside with a lab coat on. I feel I'm being watched after spending hours outside, I often laugh to myself and think they must think I'm nuts, I've been outside for 5 hours washing the car and everything else that goes with it.

Great video buddy keep smashing it 💪💪

Great instruction video. Thanks for sharing. Learn’t a lot.

I need some test about how different types of snow foam, with different PH levels remove waxes and moreover if diminishing beading is different from the actual protection of the wax or sealant.

I find it's much better to quickly rinse out the bottle first and then refill it with clean water before reattaching the bottle to the lance and running it through the pickup - this way you are rinsing the lance properly and won't still be having product going through the gauze (as you can see happening at 12:50).

Hello Specky from Australia🙃This is a copy of my post to another detailer about my thoughts on how to do snow foaming.... "I'm sure this will open a can of worms but to help any brand of snow foam you should start like this : rear of car 1st starting at lowest areas and then carry on to the lowest areas on sides front and then work your way up till you have finished at the roof...This will give your snow foam the longest dwell time at the dirtiest areas.. When it comes to rinsing off again start at the bottom and work your way up so you can easily see where you have rinsed off rather than washing it all off in some random rinse method.. think about it it does make perfect sense". I'm glad I've found someone who shares the same thinking:)

Great video as usual. I think snow foam is the biggest con out there. I’ve tried dilution ratios both in line with manufacturers instructions and not. I still use it but just as a quick prewash. I find it doesn’t do much at all and may even be pointless but just to chuck it on and leave it for a few minutes is ok.

Hi Specky very interesting. It all makes perfect sense except rinsing the car prior to snow foaming. I normally use the snow foam on the dry car as i feel pushing dirt around with a pressure washer could actually induce scratching, so softening the dirt as snow foam does works better for me.Thanks again for sharing the bottom to top rinse it makes perfect sense.

Great vid. I've always changed out the orfice to a 1.1mm and it helps produce even thicker foam

Liked the slip into local non youtube accent when speaking to the passer by 😂 dread to think how my teuchter accent would come across! Bilthamber autofoam at 4% basically works as a touchless wash for me up here in winter, need to try the GT stuff though!

Excellent. Really enjoyed that mate. Only thing missing was your magnifying glass 😅👍🏴󠁧󠁢󠁳󠁣󠁴󠁿

I agree, I always rinse first, snow foam, wash with new microfibre towel, then rinse off, then chamois dry.

I like to prerinse my car with a 128:1 dilution ratio of ONR in my pump sprayer for the detergent effect and the surface lubrication, the sheet high volume/low pressure water to rinse it off.

Waiting for the Specky lab-coat merch next.... 🤣...and for Paul to wear one on his next video, i think his neighbours will get him collected in a padded van, i know mine would, but what a laugh!!! I'll must dig out my AutoBrite Parma Violets purple foam, looks cool and smells divine!

Great video as always. Dr Specky could you apply the lab coat to Pre wash - APC, Citrus, TFR etc - Are they pretty much the same or are they specific dependant on what type of dirt you are looking to remove?

brilliant review thank you

Great video and tips. Thank you

Hi sir, just stumbled across your channel & it is very informative. Would like your take on the use of metering tips for foam cannon like the griots metering tips. It is claim to automix the solution without diluting them. Thanks in advance

Both this and the Part One video were very interesting, informative and well expained. I'm not a fan of pre rinsing before snow foaming for the simple reason I don't want to pressure wash dirt-bourne grit off the panels in order not to induce scratches. Instead, I see the job of the SF to soften the dirt and carry it down. Even if it has to be done twice. Neither am I looking for the SF to remove road film. That's the job of my contact wash. Regardind PIR, pre soaking blows that away as the dirt would now be soaked, therefore the PIR has been reduced. No?

Top man with another top video. Thank you mate I pretty much use my snow foam as you explained you added a couple of excellent points that now are going to give me better results. Thanks again sir, you are one of life's good guys. Take care, Pol

Really well presented video. Thank you

Point of snow foam , to dwell soften and encapsulate loose dirt and grime ,so if it's done it's dwell time then roof down is sense , but hitting the dirty lower half first and letting rest run down is ok I get it , I don't foam but pre wash if dirty or just thoroughly rinse wash rinse dry etc job done

My question is, do you have to buy the applicator or can you just use the soap dispenser thats supplied inside the unit where you just turn the nozzle to the soft setting that sucks the foam up through the hose? I have a karcher pressure washer. Cheers from Australia 🇦🇺

Hey buddy another great video. Just wondering if snow foam lances are universal (connection for the power washer) or are the washer specific ?

Now I know why you and civicky asked me at Waxstock which way I applied and rinsed snowfoam. And I replied bottom up and stated why. At the time I thought it was just a random question.

I like the honesty regarding pre-rinsing, too many people want an exact answer or recommendation. Experimentation is the key, work out for yourself which method better is for your own situation. My car is rarely dirty so pre rinse with water is a waste for me. The wife's car is another matter and I pre-rinse that with a citrus pre-wash. The top to bottom debate, if its been dwelling for 5mins and rinsing takes a couple imo makes no difference.

Great video Science Specky, agree with what you say, for some reason where I live we get a lot of sand in the air (fuck knows why I live in Manchester nowhere near any beaches) so I always give the car a quick blast off with the pressure washer.

11:06 its funny, no matter where in the world, If you wash your car there will ALWAYS be a person walking by saying that you could wash there car too 🤣

Why do I get streak drips when I’m done and drying ? I did half the car this time to be faster and same result . Foam , spray down , pull in garage and blow dry. It has streaks I have to towel off.

Easily the best 2 videos you have done & absolutely spot on with everything you have said. I've been arguing these exact points for years & still continue to do so. I have also shown in my own method that rinsing the first then allowing to dry while you do the alloys before foaming does achieve better results. That is my own specific scenario though with nice scottish water which our neighbours south of the border are not blessed with so they need to worry about water spots while we don't. (Does open up another argument about water spots on a dirty car though & if it's an issue 🤣). Excellent video though & very informative 👌

#0:11:04 cheeky neighbour "wash my car too" response 🤣

Great advice My foam will be arriving tomorrow to try . However I have washed my car today 😂

Great ideas thx

Great video! What pressure washer do you have/recommend btw?

The lab coat always makes it sound so official like a government news broadcast lol but great info and advice top man.

Great video. Dr Speck. 🤓 👍

good stuff, finally subbed

What make/brands were the two lances? Is there a reason the first one looked thicker over the second? Which one is better, more desirable, as I would prefer the first?

Loving the video content lately. Product reviews are great, but at a time where numerous brands are the same re bottled Product with a different name, its nice to see some how to style content instead

The thing i found is once a year clean the lance head as it get all gunged up and dries into a thick mess. I am using Chemical Guys snow foam so it maybe just that compaired too other makes.

Never heard of snowfoam until today but after watching this just ordered some autoglym snow and a cheap Nilfisk foamer. (It’s the only one for my cheap nilfisk power cleaner. Thanks

Have you got any ideas I can use for my brake discs every time I wash my car they go rusty then I drive down the road and theres rusty bake dust all over the my black wheel. So Frustrating when you spent hours cleaning your car.

Foaming first has to do more with not inducing swirls and micro scratches in the pain. Theory is the pressure washer will drag the dirt, grime, salt across the paint and cause micro scratches. Adding the foam lifts dirt and provides a lubrication layer to the paint so the dirt doesn't scratch the coatings. Now I couldn't tell you how much of an issue this is because I track my car and scratches and dings on the paint is just part of doing business. However if my car does get dirty enough that a foam rinse, foam rinse, dry isn't going to clean it enough then a pre rinse isn't going to do anything anyway.

The best part about living in the UK is you don't have to worry about sun drying soap and water on your car, leaving spots. The week of sun goes by pretty quickly XD

I only use snow foam to get as much shite off the panels as possible. Keeping my mits & other cloths cleaner, meaning less likely to scrach the panel if I was to use shampoo first. It's just to get everything lose & get lose grime off. That's all I use it for pretty much as a pre wash.

Some age old debates here 🤔 After much thought about rinsing top to bottom or bottom to top and if to pre rinse or not.. I don’t think there is any right or wrongs, like you said the differences are marginal and depend on the situation/dirt levels you are dealing with. More important to use good products and be thorough with rinsing than whatever way you choose to do it.

Cheers specky Things I've noticed, I get better results foam going on dry, and actually using less pir is working out better which I can't work out 2% pir with my bilt hamber seems to be better than 4% I just don't get it

Try getting the Snow Foam to stick when you've Ceramic coated a car it's a nightmare, is that a bad thing?

What if the snow foam manufacturer does not have a PIR (which is rare) and has a general dilution ratio. In the case of the Snow Foam I am using the dilution is extremely weak.

I allwase tell people that the best way to wash form the bottom. To prevent dilution

Very informative video. Pity I didn't get to interview you at Waxstock. I will get you next year. Top work buddy.

Sorry for my ignorance as maths is never my strong point, but how many mls of snow foam do you put in the bottle before filling the bottle up please? Or how many cap fulls of snow foam ? Thanks

The foam cannon S V3.0 i just bought it today and what do I see? a youtuber waits for 5 minutes after this product foams the car and says that the body is dry. In other brands or in the previous foam cannon of mjjc, this problem has grown and the vehicle remains wet. I'm depressed. Is this going to harm the car? I'm curious about your opinion on this.

What is the foam cannon you are using in the video clip.

Another great video I love the geeky side Especially as I’m Steve McMahon Aka Geeky detail reviews Great to meet you at Waxstock on the weekend. Was a pleasure

Nice1..Specks & thank u

I do my wheels and tyres with fallout remover first, then rinse and then put on alloy wheel cleaner and snowfoam over that when I'm doing the rest of the car then I rinse off the lot, seems to work well at bringing up the wheels without any need to scrub with a brush.

How do you mitigate pebble/stone ricochet from the floor?

When washing the car on the drive using snowfoam of choice, is it safe when it runs off the car and into lawn or plants. Will it have a detrimental affect on soil as it is a chemical. Just asking thanks.

Wow...there should be a BSc Hons degree in snow foam application 😂

I've noticed that the British guys know how to wash cars better than the Americans.

Watching this even I don't have a car 😂

What is the best snow foam lance on the UK market?

Good stuff 👍

Which lance would you recommend. Never used snow foam before !

I use 100% soap, with arm and hammer soap. Don't care about the cost. But it mixes with water anyway even if you use 100% soap. The water is the propellant.

Do you actually wash your car by hand using a wash mit? As well as snow foam

On a cold day no need to pre rinse just throw snow foam straight on the panel on warm and hot days pre rinse to take any residual heat on the panels so snow foam doesn’t hit a warm/hot panel

I’ve watched so many videos where this happens. Mine goes on and stick for ages. I’m just using Polar Blast.

Just watched both vids back to back. Sat down and mulled over your conclusions and the significance, whilst supping a cup of tea and munching on a hobnob (chocolate without saying). Conclusion? You're a genius! Very interesting. Just got to 'go with the flow' (see what I did there?) Get calculus out and see what i get. Oh, was she asking for a date?

Deluge 1:10 is 10 %. Later the instruction says 2% in general and 3% for heavy duty. What is right?

Perhaps not much of any performance difference of simply waiting longer overall before rinsing from the top in one go vs going from the bottom in stages, for the sake of leaving the foam on longer. Some good tips there, thanks.

Can’t believe I’ve not rinsed out my SF bottle/lance as shown in this vid. Bloody obvious really! 🤦‍♂️

Rinsing from top to bottom or bottom to top, for the few seconds it takes I'm not convinced that it really matters. An extra 15-20 seconds soak time isn't going to make much, if any, difference at all.

I’m sure I heard the seagulls laughing at the ice cream seller washing his car 👍🏻🤣🤣always one that walks past as well do mine next 🤦‍♂️

As long as snow foam makes my brown and green van look almost white again, I'll be happy! 😂

I like the new Science Specky 👍

right, so for one whom is new to this sort of car wash...this is the touchless idea right?

What lance do you reccomend?

I see what you mean with the washing bottom to top, as if you go top down just the water running down the car has washed the snow foam off not yourself with the pressure washer itself.

I see no point in rinsing bottom to top. The extra 10 seconds of dwell time couldn't possibly make a difference if you've let the foam sit all over the car for 5 mins or so anyway. Plus if it's all being rinsed off what's the point of which direction you go if it's all coming off anyway? Like if the argument is that top to bottom dilutes the lower product than who cares if it's all about to be rinsed off, it's all had plenty of dwell time so I see no difference or advantage in one or the other

What jet wash and snow gun are you using?

John Hogg from Wish!! 🤣🤣 Good video. I'd also suggest learning to dismantle foam heads too.

My m8 is a detailer, and he did a test on snow foam .He put white blankets on the floor to test if snow foam removes dirt ,and it don't, it's a waste of money and another stage you can save by not using it ,only thing is it just looks good ,just prewash then use a contact wash

Im the same by rinsing from the bottom upwards

Pre-rinsing dilutes the product and makes it less effective as a result. It only makes sense to do it when there's so much dirt that the snow foam wouldn't reach the surface of the car.

Of you want longer dwell time, at the bottom, then why not repeating the foam stage directed at the bottom on the second round.

What product was in the 1st lance ?
