This works beautifully for doing what’s promised ie removing rust. I found however on various items that when taken out of the solution they had a quite thick black oily coverage and once wiped of the items then had changed colour to a dark grey/black . I am not concerned with the colour change but the oily deposit on the surfaces puzzles me. I didn’t think any of the items had oil on them pre dip ,otherwise why did the rust so badly , but I am guessing they must have had . Can you answer this conundrum for me please and Pam I right in thinking that I should degrease any item with say brake cleaner before putting in the solution. Thank you for such a wonderful explanation and the substantial work you have done in achieving the splendid end result and it very inexpensive and it works

Can i use stainless steel to store the chemical or to boil the bath?

i Like this original look more than "brand new" look. Looks really nice

I find electrolysis is the best way of removing rust on small parts. You can use an old plastic bin to do larger items.

Tried browsing the comments but here goes: How do you dispose of the used up solution? We don't have traditional drains here just storm water so can't really pour it in there, can I dilute the solution further with water and just chuck in the garden? It's technically all food grade items with some "evaporated" rust in there. (see what I did there, LOL).

Bullshit

Thanks for the formula, I converted it to imperial just by using the metric as percentages because 1 liter of water 1s 1000 grams. Awesome.

Excellent job 👍,I love evapO rust ,but as you've said it's Expensive. I'm definitely going to use BYB's rust remover . Thanks

I was too lazy to do the exact formula since i was doing it in a 60L plastic bucket. Alot bubbled over at one point and I didn't feel like leaving the garage go to go get dish soap so I used karcher outdoor pressure washing soap. After about a month the fluid is pitch black from having numerous car parts sitting in it, it doesnt seem to cause any problems of having things sit in it for a week or so at a time probably because it has gotten cold around 10C probably. The most surprising thing I can take away is after wiping down the part no rust has returned at all. The parts are sitting out in the garage and not a thing has changed. I grabbed some fluid into jars for screws and it seems to have worked well and not gotten black. I have noticed some screws are spotless losing whatever coating they may have had and the metal has become more of a gunmetal color which I usually use a wirebrush disk to clean off.

Awesome! Thankyou. But is the dish soap necessary?

You can even drink this, it’s good for you (minus the washing up liquid of course).

Great video, thanks for sharing. I have one question - I use a lot of rust killers/ converters in car restoration, very expensive and not very good. I need to treat sections of a car which can't obviously go into a bath of your solution. What do you think you might add to it to make it to be applied to car sections so it won't run off - In the same way Naval Jelly is a more solid substance.

Great stuff! What can you recommend to preserve the part after this treatment? Also, is it just rinsed with water afterwards, to clean off the solution?

Heres a question. How affective would your citric acid and sodium carbonate solution be when sprayed on a surface (vs submerged). Worth using or more effective to just grind rust off?

I find it amusing you start your cheap homemade rust remover by making cheap Alka-Seltzer. I am a chemist myself like others who have commented, there is nothing much to add, your video is solid. Something I didn't learn as a chemist is that dishwater detergent is a magic ingredient for many ways of cleaning metals and for paint and fat removers, not just for rust removal.

Thats a Bren Gun magazine

so you showed EDTA molecule while talking about evaporust, how your solution is against something like EDTA-Na2? its not that expensive

Alka Seltzer has citric acid and sodium bicroabonate in it. I wonder if it would work same.... (it has more Sodium Bicarbonate than Citric acid though)

Thanks for your well thought out video well done

It is a Bren gun Mag. 303 rimed.

This worked amazing and I totally appreciate you sharing your recipe!!!

Would this work on tools with wood attached or would it damage the wood?

You are amazing sir

Loved your channel before and even more now. Thanks a huge bunch man.

Will this mixture harm the rubber in the tires...

4:30 Easy on the dish soap. A tiny bit is already enough.

Is this safe on motorcycle chain with o-rings?

Has anyone tried making this into a gel for parts that can't be submerged and if it damages paint? For example to use on a painted panel van which has a spot of rust.

Brilliant!! Thank you!! May your pillow be cold on both sides

@adamsavage

Thank you!

Excellent video.

I watched a video where the guy used about a half gallon of animal grade molasses and looked like 5 gallons of water and he put brake rotors in it and a few days later the rust was gone, the rotors were badly rusted , he said it has bad smell so put a distance away from house LOL

Any idea how to make a product that applies more like a thick paste than a liquid bath?

Superb!

thankyou for posting

Does this remove the bluing from firearms?

3:07 for all those who just want to know how to make solution.

Brengun magazine.

Thank you a lot for making this "open source" ❤❤

Okay

This looks fantastic, however the problem I have is that most of my rust removal requirements are on objects that cannot be immersed in a benchtop container, large farm machinery as an example. Is there a way to make the solution adhere to surfaces, do the job and then be pressure washed away.

Great video, thank you so much 🙏 ❤️

Great video. Just a few questions hope someone can answer. Would this work on chrome parts with some rusty areas without harming the good chrome? What would be good rust inhibitors for after using this solution? One last question, how do you safely dispose of this solution when it is used up?

made a batch. absolute magic

@Beyond Ballistics - Random Question: Is it a food safe solution? Or could it be a foodsafe solution once properly washed down after rust treament of a stainless steel part?

My friend. That was an excellent video and so very helpful too. Fantastic solution. Citric acid and washing soda... BRILLIANT !!!

Thank you so much!

This is a very well done and useful study. One thing that may cause some variation in results is that sodium carbonate (washing soda) is not always the same. The anhydrous form is what you'd normally encounter in a chemistry lab, and seems to be assumed here based on 40 g of sodium carbonate being equivalent to 63 g of bicarbonate or 30g of hydroxide. The confusion is that at least in the US, the usual thing sold as washing soda is the decahydrate, so you would need a lot more: 107g of that to provide as much base. The consequence of too little base would likely be more rapid attack of bare metal, but it should still dissolve rust.
