How to clean tarnished brass?
How to Deal with Tarnished Brass 1 Wash the surface of your brass item with soap and water to remove any contaminants that may get in the way when you start scrubbing the item with cloth. All surfaces, even the grooves and crevices, must be free of dust and grime as they can pose some hazards on your item’s surface when they mix with your chosen polishing agent. 2 Rinse the newly washed item thoroughly to remove the lather and dislodged dirt from its surface. Any foreign material left could potentially affect the effectiveness of the cleaning process. Then wipe with a clean cloth before letting the item dry completely. You can sun dry it but don’t leave it outside for too long so the surface won’t burn up. 3 Choose between commercial polishing products and natural products. There are scores of ready-made polishing products available in your local hardware store, but check their concentrations carefully so you won’t mistakenly buy one that’s too harsh for your brass item. Sometimes, especially if you are dealing with flimsy plates or tiny rods, it’s much safer to use natural products, such as ketchup, vinegar, and baking soda. All of these have just enough acerbity to melt away tarnish without scuffing your brass item. 4 Once fully buffed, seal the surface of your brass item with a clear lacquer to preserve its sheen for a long time. This way you won’t have to clean and polish your brass item too quickly.
