Tarnished brass taps can be cleaned with the application of a lemon juice and baking soda solution. To create the mixture, use half a lemon’s worth of juice combined with a teaspoon of baking soda to form a paste. Then, use a soft cloth to apply the paste to your brass fixtures and fittings.
Another option, meanwhile, is to soak tarnished brass taps in a vinegar-based solution, one that features two parts water and one part vinegar.
