Cleaning Marine Tarnished BrassApril 21, 2009 Hello, Steve Utermahlen
First of two simultaneous responses -- April 29, 2009 I suppose muriatic acid would work, but citric acid also does an excellent job and is much safer to work with. Let us know if we can help.
Second of two simultaneous responses -- April 30, 2009 Try 5% ammonium citrate solution(50 gm citric acid/ 1lit water +add ammonia until pH is 9, cold solution works slow, hot faster/80 C/).If your objects are wax or lacquer finished you must remove coating first. Hope it helps and good luck! Goran Budija
