[QUOTE="Circus, post: 7842598, member: 51195"]The easiest and cheapest way to clean copper and brasses is by doing what metal workers do to clean and remove flux from it. They use a pickle solution sodium bisulfate Better known as Pool pH reducer. Sodium bisulfate is used primarily [B]to lower pH[/B]. it also is used in metal finishing, cleaning products, and to lower the pH of water for effective chlorination in swimming pools and hot tubs. It works best at about 180ºF [COLOR=#ff0000]DO NOT HEAT TO BOILING BECAUSE DANGEROUS FUMES ARE RELEASED.[COLOR=#000000] Hot tap water will work, you will be able to see the change in a short time depending on the type of deposits.[/COLOR][/COLOR] [COLOR=#ff0000][COLOR=#000000]Use only glass or plastic containers to hold and clean the items.
