You can use citric acid ⇦this on eBay or Amazon [affil links] solution(5%), or ammonium citrate solution(mixture of 5o gm citric acid /1 lit water+ some ammonia(25%), pH of solutions must be 3,5 for iron and steel, pH 9 for copper and its alloys, last solution can be used for gilt pieces,i n principle one solution for one metal). WD-40 ⇦this on eBay or Amazon [affil links] or Ballistol can be used too (works very slow).
Good luck!
