Thanks for the future video ideas! Please let me know if there are other rust removal products you'd like tested. Thanks again, Todd CLR: amzn.to/2QnajyB Krud Kutter: amzn.to/47V6Gpp Evap-Rust: amzn.to/32mWw0W Loctite Naval Jelly: amzn.to/2EwdktN Muriatic Acid: amzn.to/3hmmoA3

The Coke has a great use when removing rust. Mix it with some rum and drink it while waiting for one of the better cleaners to finish 😄. Awesome videos 👍.

This has amazing high school science project energy, and I mean that in the most complimentary possible way.

I use Evaporust all the time, but the thing to bare in mind with it is that it's a chemical reaction that is VERY temperature dependent. At normal room temperature it's quite slow, and almost ineffective at below 60° However if you put parts in a pot and heat them up to 100° - 120° it works VERY quickly, like Muriatic Acid quick.

This guy is the the most concise tester on the net. Hands down. That's some accolade for the amount of people who use it.

Please, never stop making these videos. I can't tell you how nice it is to have so much empirical data on commercial products. I like your methodical approach to testing and presentation of data.

This is one of the best channels on KZfaq. Your tests are so incredibly useful in daily life when purchasing products. Nobody else does testing like this. Thanks so much.

I know I'm probably late on this, I use evapo-rust when restoring car parts, mainly because it does work fantastically and is very gentle at the same time. Also the evapo-rust you can use over and over again. I usually will strain it to get any large particles out and then keep using it. I also usually let parts soak for 3ish days. Also evapo-rust has no harsh acids so if you spill some it's not a huge deal.

Given the fact that it's less than half the price of Krud Kutter, works almost as well, can be used over and over (until it's black, which takes a long time), won't hurt you if you touch it and can be disposed of by just dumping it out or putting it down the drain, I think Evapo-rust is going to be my choice for the projects I have coming up. This is an excellent video - thank you!

Great experiments. Arguably this is more practical advice than, say, whether or not I can run my lawn mower on WD-40 but I do appreciate the bizarre tests too.

FINALLY!! A KZfaq video showing a well-designed comparative study with controls!! Thank you for this!!!! Your experiment has been extremely helpful to me!!! Yay!! Great work!!!!

We’ve used Evapo-rust at work and I’ve been SUPER impressed with it. They do warn that it does draw some carbon to the surface, but I doubt it’s an amount that would change the strength of the material. It takes time, but holy crap, it does work. “Started to eat some of the metal”. That’s not good. Evapo-rust doesn’t do that. Something to consider. One thing we were able to do with it was remove some rusted and seized 1-1/4” studs from a massive valve body. It will creep in like a penetrating oil, and it actually seemed to be more effective.

Thanks for the uploads over the years. I would say that I've learned something useful from every single one. Putting this type of program on youtube is pure genius as I believe almost everyone can learn from these uploads.

I absolutely love these videos. You do a great job of comparing products in a controlled, measured setting--without hyping any sponsored products. It's always a gamble when you buy and try a product. You are doing us a great service by really testing these products well. Thank you.,

This is the second video of yours that I've watched and I'm extremely impressed by your presentation. You do a very good job of explaining the products, giving them a good amount of time to work, and using the control to do a comparison. Very methodical and easy to follow. Thanks for work and for sharing your results!

Todd, Dude, you are rockin' these product testing videos!! I only just now realized how many of your videos I have watched. I've begun to look for them if I'm wondering which product to buy for my repairs and maintenance activities. I enjoy the style you have adopted for your testing - the straight-forward, get-right-to-it approach is much appreciated. Keep up the good work!

Thanks for another great video ! An old guy once told me he used WHEY to loosen rusted manifold bolts on a marine engine. He said you could then turn the bolts out with your fingers. He chose to use whey because they used to feed their pigs on whey from the local cheese factory, and the iron feeding pots never got rusty. I've had good results using whey on rusty tools, bolts steel wire and chain. Sometimes I left the rusty item immersed for a week or more. Can be a bit stinky in the hot sun, but put a lid on the plastic pail. When done, wash the item off with soapy water, dry it, then apply a coating to prevent rusting again. As a quick fix, I threw several lengths of chain in pails of used engine oil over the winter. I may wipe off most oil, leaving enough so I can store chain in damp conditions. Or I may clean up and spray cold galvanize or some other pail coating. Whey is cost effective for big jobs if, as I did, you get pails of whey for free from a cheese factory. [ RIP Uncle Billy ]

Hardware store employees need to start watching your videos instead of recommending products without any actual knowledge of how well they perform..

I love this channel. Just found it recently. Your approach to testing is exactly what I was looking for. You have data backing it all up. **You clearly display all the numeric data ** which I find a lot of other not doing. In addition you provide price to performance comparison. THANK YOU for being what I consider to be a gold standard and why You Tube was created.

You make amazing quantitative, real-world comparisons. Excellent! They are also clear and well-produced. I'm a fan.

Sometimes you definitely get what you pay for. The Krud Cutter did an amazing job. It’s definitely worth the extra money 💴 in my opinion. I would buy it... and I’m pretty frugal lol 😆. My favorite videos are when the less expensive products/items beat out things that cost 5-10X as much. But hey, we all occasionally have to pay. That’s the difference.. knowing when to save and when to spend. I love the reviews and comparisons. God bless and keep them coming.

Coca cola & whiskey is best, after a couple of glasses it makes everything look fantastic....relationship, job, bank account, even rust!

Great video and testing setups Todd! The Muriatic Acid works better than anything I've ever found for removing rust and scale. The key to not losing much metal is short immersion times and neutralizing the acid right after removing the item from soaking with a baking soda and water mixture. I've worked with Muriatic Acid many times over the years and I don't think it is as dangerous as most people seem to think it is. I have never been burned by it even when it has gotten on bare skin, however, you DO NOT want to inhale any of the vapors or get it into your eyes. It will burn mucous membranes rather quickly. The craziest thing I have ever seen with respect to Muriatic Acid is watching a drunk grab a bottle of it and take a big drink, thinking it was beer. Needless to say, he spat it out quickly and was dosed with a baking soda and water mixture to neutralize any remaining acid. He never exhibited any adverse symptoms from his "big gulp" and carried on his drinking afterward...some people... How about a video showing people how to "sharpen" old metal files using Muriatic Acid and Vinegar? I've tried it and they both work, but the acid works much quicker. The acid works within 10-20 minutes and the Vinegar takes several days. It does extend the life of your files a good bit too. I didn't believe it until I tried it for myself, collect some old files and give it a try. Just be sure to clean and degrease the files first. Thanks for the video!

Such a thorouh walk through in this video. Im in awe. Thank you for this review!!👏🏾👏🏾👏🏾👌🏾

Your timing is awesome. It never fails that one of your tests pop up when I am getting ready to tackle a project related to your video. This time, it's a 2007 HD Dyna Low Rider fuel tank on a bike that has been sitting for over 6 years with fuel in it. Nice nasty layer of rust in the bottom of it that I need to remove and treat prior to resealing the tank.

You can't imagine how valuable your videos are. Speaking for myself (and i'm sure every other subscriber), they have saved me so much time and $$. Thank you sir!

You are one of my favorite contributors on KZfaq. The amount of time you spend on your tests is apparent. Thanks for taking one for the team, over and over again

Another tremendous video, I love watching anything you produce. I was wandering, did you do a follow up video on the spanner you left out in the elements?

A great video, thanks for posting. I tested a couple of rust removers along with white vinegar a couple of years ago to treat the rusted interior of my motorbike petrol tank . Out of all of them I found Evaporust was the best, followed by white vinegar. I left the tests overnight. I still have the container of Evaporust in my cupboard and I'm still using it. I recently used it on a pair of pliers I found buried in the garden and they came up pretty much like new!

Great way you test and baseline these products. Love your vids!

LOVE the clarity & presentation. Got my answers, so thanks for doing the hard work! You are awesome man!

Another eye opening and informative comparison. Thank you so much for testing these chemicals to determine which product does in fact remove rust better than another.

I like using evaporust for stuff that isn't time sensitive. You can leave it, forget it for a month and when you come back it's got the black coating over it (you don't have to leave anything for more than 48hrs though). I love using electrolysis for removing rust on larger objects. Last summer I did this to my seat rail because it was frozen in the all the way back position. It was able to treat the whole thing in about 12 hours, and I was able to put it back in the car by the next morning.

I've always thought of CLR more as a cleaner for hard water stains on bathtubs and things like that. Like the videos. Thanks for making them. :)

I’m preparing for de rusting under my car before spraying fluid film, this was so helpful, the thorough method of testing products is appreciated.

Just discovered your channel. I love your comparisons an the detail in which you do your tests. Great job…I am now subscribed.

Excellent test/review. I appreciate the cost per ounce addition. One thing that I like about Evapo-Rust is the ability to reuse it. Muti-use lowers its net cost.

I'm fairly sure most of these biodegradable rust removers contain the exact same active ingredient, but the concentrations might be different.

Just as always, you've already made a video of something I'm looking for. Rock on!

I always appreciate Project Farm's testing. Appreciate your time. I recently had a use for a product like this. I went with a 5 gal. bucket of Evaporust. I let stuff soak for 24 hours before even looking at it. The stuff did great. I followed directions, pulled it out of the bucket and wire brushed it all and resoaked it for 24 hours to get to the deep pitted rust. Rinsed off and ready for paint with ALL rust removed. I believe the key is total immersion and at least 24 hours. And Evaporust can be reused until it eats 1 lb. of rust per gallon.

A Jaguar mechanic friend of mine uses Naval Jelly to clean wire wheels (notoriously difficult to clean without total disassembly). The performance was very impressive.

Excellent study. Mildly acidic BAR KEEPERS FRIEND works well on my drum fixtures, lugs & bolts.

Hey there, love your testing videos. Very useful for craftsmen. I especially enjoyed your epoxy comparisons. Thanks for doing all of these!

Great honest video. I used Eastwood's Fast Etch on some very rusty brake rotors and was amazed at the results. The rotors looked new; I soaked them in a tub. The axles were left on the car but cleaned up nice by soaking a rag in FE and leaving it on the vertical surface.

Excellent video, thank you! One of the few times I totally believe the presentation and have no apprehensions about the accuracy of the results. I am following your channel.

Can't stop watching these! So good!

This is the second video I had watched of yours, and I just have to say you are awesome. You defiantly put a lot more thought behind your testing than the average person. With my science degrees (mostly in biology and apply Anatomy and Physiology which much applys also some understanding of chemistry and physics)I had learned to do that every thing as well. I will even go as far to say that you put more though than most scientific journals I read to get more honist results and interpretations of your results.

Great test!! Thank you all the time and effort you put into these videos!

After having accidentally mixed clr and vinegar one time, and having to evacuate my home because of the toxic gas from the chemical reaction watching you have those two products so close together during this testing had my anxiety through roof.

You have one of the greatest channels ever. Actual results.

I actually conducted this test, by accident, on a crescent wrench. I found a rusty wrench in a yard I was cutting. All I used was a wire brush with Wd-40 and 3 in 1 oil. That was almost 3 years ago and I am still using the wrench with no issues. Love these videos!

wow, the videos from 4 years ago are still as quality as 4 years later, keep iup the good quality!

Love this channel watch it many times to make a final decision on some products. A little vibration with all of your testing and you would have had different results. I've used all of the products over the years. Vinegar with vibration works wonders and it is super cheap and Way easier to nutrelize. A couple of those will continue to break down the metal for months after used. Water doesn't stop the acid reaction. Thanks man! Keep doing what you do! You have helped me and others alot.

Evapo-rust definitely doesn't work the fastest but anybody who watches handtoolrescue knows that it works pretty darn good. The plus side for evapo-rust is that it isn't super toxic like the rest.

Another very helpful video, thanks for taking the time to do these practical, unbiased tests - resist the sponsors if they come knocking !

I am kinda addicted to these videos, keep them coming, they are full of relevant info.

Awesome information. Thank you very much. You have just saved my motorhome! It would have cost me over £4000.00 to sort out the rust. But now I can do the job myself for only £250.00 and probably a second hand door. Brilliant video!

Been here since 26k subs your channel growth is all proff of how awsome your content is

I know I said it many times before, but great video! I normally use Ospho.

Lol, I have gone to your videos before I buy tools and you always have one for what I want. Starting looking for a rust removal. Didn't even think you would have a review for this!! You're amazing! Thanks for all you do!

Thanks that was definitely entertaining. I have many rust removal tasks; the information you have provided will be of great use!

For small parts, nuts, bolts, etc. that will fit in my Harbor Freight ultrasonic cleaner, I use Evapo-Rust. The heat and agitation added by the ultrasonic cleaner really help get rust out of all the threads and small spaces. For parts too large to fit in there, I use electrolysis instead. Washing soda (or Oxi-Clean) dissolved in water is the active ingredient, and electric current supplied by a battery charger does the work. Another benefit is that what is left over is non-toxic and can be dumped in the yard. That assumes that only ordinary steel was used and not galvanized or stainless steel because they will create a toxic residue. I have used Naval Jelly in the past, but in more recent years I use one of the two methods I just described instead. If I do use Naval Jelly, I like to cover the jelly with plastic food wrap to keep it from drying out, because prolonged soaking seems to work best. I also ensure that I scrub the part down with an abrasive pad and water to remove the residue completely. Great video, BTW.

I haven’t watched him for a while, but the fact this guy isn’t sponsored at all is pretty cool. (It may have changed. I’m at the beginning of the video.) Imagine when he started the channel, was making zero money, and just experimenting with stuff with his own money with no return. Good for this guy! Liked and subscribed.

I watched your video and was amazed by your results with evapo rust. I have been using it for years now and it works best for me and it is my go too product in removing rust from nuts and bolts, tools, and even a rusty black powder gun barrel in all worked great with no rust left and all items functioned as they should

Wonderful, practical test. Rock on Project Farm at producing quality tests that have practical value. Thank you!

Here I thought evaporust was expensive! I like that evaporust can be used over and over again and non-toxic so if it spills I don't have to worry about it.

Great comparison, thank you! For those of us that do automotive work, it would be very interesting to see which rust remover/converter products are most friendly to plastic, rubber, and soft metals. Knowing what cam be used to take care of rust under a vehicle without having to pull everything apart would be very helpful!

Thank you for another great video. I use white distilled vinegar on a regular basis for rust removal and I've found it extremely effective. The trick, however, is time. I've soaked rusted parts in vinegar and the rust actually foams and gathers at the top of the soaking container. It takes a few days opposed to a few hours.

This channel is the best!!! Every time I have a question he's done a video on it.

Great video! I've used muriatic acid in the past to restore automotive parts. Although it's extremely effective it also strips protective finishes from nearby metal. Using this stuff in my garage caused most metals in my garage to rust. It completely rusted out my drill press and a bicycle that had never seen a rainy day in its life. Just the evaporating gases caused this. Very nasty stuff. I also left some bolts soaking in it for over a month and when I removed the bolts they crumbled in my hand. Love the content!

You are amazing bro, i look all over the net for which product it's good for clean the rust on car's frame. Now i think i get what i looking for it. You are super. I wish you all the best bro.

Great video! I needed something to get the rust out of a boat fuel tank and thought I would check Project Farm. You did not disappoint! Thanks again!

Always the best testing products channel in this planet, thanks for shearing all this amazing content.

Try high temp RTV silicone as a head gasket material to test its durability against heat and pressure.

I was trying to restore my recently deceased father's old stuff. And your video is really educational. You got a new subscriber. :D

Hey I wanted to say thank you for making the video I’m 100% sure it helped out others like me appreciate the video

Another great test. I’m sold on Kris cutter. Thanks for sharing.

I got a kick when he had to tie strings around his nuts just to dip them in coke

That coke bottle was so embarrassed it tried to sneak off at the end of the video.

Thank you so much for your detailed experiment. I was able to clean my rusted golf club! Cheers!

This could possibly be the best channel for making a good choice 👍

In addition to my Scout 2 (They LOVE to rust) I have an extensive Medieval arms and tool collection. Vinegar works great and is the classic means for rust removal, plus it's cheap and leaves a natural metal bluing. It works slowly, however. I can't explain your nut results with it.... and BTW Amazon has gallons of Crud Cutter for 17 bucks and free shipping if you have Prime

Love this channel. I would like you to test Rust-oleum Rust Reformer paint. I would like to know if it lives up to its claims.

Thanks. I've been debating on getting some Evaporust mainly since it's reusable and this helps a lot.

Great content . I needed to remove rust from a transmission drum so I bought Zep rust remover and soak the drum in it . I did a wonderful job removing the rust but once exposed to air it rusted even worse than before treatment . I tried it again and immediately rinsed the part after removal and it STILL rusted . I learned a lesson :)

The active ingredient in the Krud Kutter and Naval Jelly is phosphoric acid. It might be interesting to try a product like a Klean Strip Phosphoric Prep and Etch, which has a higher concentration of phosphoric acid and costs a lot less (~$0.12/oz). Phosphoric acid is great as a rust remover because it reacts with the rust and makes it water soluble and does so at a rate much faster than it reacts with steel. When it does react with steel it forms an iron phosphate coating, which slows further etching from the acid and also slows future rust development. Ideally, to restore a piece of rusted metal, you would leave it in the phosphoric acid long enough for the rust to be removed, but not long enough that the phosphoric acid starts reacting with the steel and forming the black phosphate coating.

Very informative as always. I'd be very interested in a similar trial of rust converters rather than rust removers. In the UK we have some good ones, my favourite being Built hamber deox C, or Hammerite Kurust. I used Deox C to restore some drive shaft shells on a rideon mower deck. Amazing. Thanks for such a brilliant channel.

Your test are amazing keep doing it!

I have recently come across your videos and really enjoy them! Just wondering if you ever went back to that wrench that you left outside after it was cleaned by the krud?

Great Video! 50 years ago, my Grand-pa taught me to use Molasses as a rust remover. The same stuff you buy in the grocery store. I use a 50/50 mix of molasses and water. It does take alot longer to remove the rust than what your test times were, but it is a cheap and non-toxic way to remove rust. I think I'll try the Krud Kutter that you tested, that really impressed me.

Super handy video. Thanks!!!

You are a heck of a scientist. Thank you.

People don't see the work and planning that goes into your videos, thanks for the content

Brake studs were a perfect choice for your test . The Kurd kut very impressive. If I remember correctly, the naval jelly was designed to create a barrier layer that is not to be removed. Kurd kutter hands down winner. But in a vertical application Naval jelly will be the winner. great work man!

Im suprised how white vinegar did. I always soak my old rusty horseshoes in white vinegar overnight and next day everything brushes off easily.

Hey project, This is the best channel on youtube. Thank you Mr Farm

Thanks for the great video, my 5th wheel ball was stuck in the box and not wanting to be removed, after about 4 sprays and 2 days the Liquid Wrench did the trick.

Hot damn Krud Cutter. Never even heard of it before, only Evapo-Rust with all their sponsored content.

I dilute muriatic acid 50 percent with water so ot is extremely effective but gentle enough not to remove metal. It can also be reused a lot befpre ot is no longer effective. That's when i neutralize it with baking soda and dispose of it down the dtain. I think my method is the least expensive and most rffective. I give it 5 thumbs up!

I really enjoy your shows. Your methodology is easy enough for me to follow. I once purchased evaporust, then I wised up and read the ingredient (oxolic Acid) so I now purchase oxolic acid from e bay. I get enough powder to make 5-7 gallons for about 17-20.00. After watching the molasses work I will definitely switch, or cider vinegar. Oxolic acid is not toxic but safety measures gloves, goggles, etc wouldn't hurt.
