This is the charm of copper itself. Natural oxidation of brass is inevitable, but oxidation will make it more retro and does not require special maintenance. But if you want to keep it bright, in addition to buying professional brass maintenance fluid or polishing paper, you can also use the following simple daily maintenance methods: 1. Soap or mild detergent: If it is just dusty or dirty, not blackened, soak it in warm soapy water and wash it with a soft cloth. Particularly dirty places can be gently wiped with a toothbrush. 2. White vinegar, salt and flour: These versatile kitchen items can be used to make a paste to clean blackened brass. Dissolve a teaspoon of salt in 1/2 cup of white vinegar and add flour until it forms a paste. Rub it on the brass, rinse it with warm water after 10 minutes, and let it dry. 3. Water: Heat a little water, add 1 tablespoon of salt and 1 tablespoon of white vinegar to make another natural brass polishing preparation. Apply this preparation to the brass and wipe it dry with a clean rag.
