Try 5% ammonium citrate solution(50 gm citric acid ⇦this on eBay or Amazon [affil links] /1 lit water+some ammonia ⇦this 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!
