Looking for a chemical to use in a submersion tank that will remove rust from automotive parts. Want something that is e.p.a friendly.I heard about an electrical process that does this job but not sure how it works.Thanks in advance for the information...

Try 5% ammonium citrate solution(50 gm citric acid [on eBay or Amazon affil links] /1 lit water+some ammonia [on eBay or Amazon affil links] -pH must be 3,5).Only citric acid works too.After treatment neutralize with 5% baking soda [in bulk on eBay or Amazon affil links] solution(to avoid flash rusting)Hope it helps and good luck!
