Rust removal with vinegar??

Has anyone used "RealLemon"  I heard of people swearing by it.  It's basically Citric Acid.

Electrolysis is the best way I have found to remove rust thus far, to date.  No fumes, no hazardous chems, and it actually converts some of the oxides back to metal (less pitting).    Thinking of doing a write up on it, but I'm sure there is one on here somewhere.

When I don't want to spend money on Evaporust I'll use the lemon mix. I used it on my shock plates, plus front bumper brackets, brake backing plates, etc.



The part that still shows rust was about to be put back in. It was quite a bit worse than the rust that was still remaining.

Phosphoric acid is my go to rust remover, rinse then clean with ethanol and you have a ready surface for paint.

Coca Cola or WD40 is good for getting rust off chrome also

I tried a mix I saw mentioned on Moparts- 1 gallon of white vinegar with 1/3 cup of salt and 6-8 ounces of lemon juice (Real\Lemon).  It actually worked pretty well.  I used it on some bolts and brackets (that were pretty bad) as a test, it got rid of the rust but left a slightly rough texture that might not be great for sheetmetal.

This method has been around since the 1970's in the rusty beer can cleaning hobby, cheap safe alternative if you don't have easy access to Oxalic acid. This combination is similar to using Citrus acid. LEON.
