NON FRUIT VINEGAR
METHOD OF CLEANING:
Make a solution from NON-FRUIT VINEGAR and salt. Allow the salt to dissolve. You can also use table salt. Immerse the brass or copper items. While immersing, the colour will start changing. Leave it for a while. Take out and wash with a dishwash liquid and scrub. For bigger vessels, dab the scrub with the solution and wash as usual.
NOTE: For 1 cup of vinegar, 1 tablespoon of salt will be best. The quantity can be increased or decreased depending on the number of items you clean.
