How to Get Stains off Brass

Buff the stain on the brass vigorously with a microfiber cloth. Often, you can remove minor stains and tarnish on brass through vigorous buffing alone, saving you the time of making a stain remover. Buffing in circular movements or in straight lines is acceptable.

Slice open a lemon and sprinkle salt on its cut side. Rub the cut side of the lemon containing the salt directly on the brass object, making sure to completely cover the stain. Rub the lemon and salt off the brass with a microfiber cloth and continue rubbing until you remove the stain.

Mix flour, vinegar and salt in equal amounts until you have a thick paste that is roughly the consistency of dough. Spread this paste over the stain on the brass and allow it to sit for one hour. After an hour, remove the paste, wash the area with water and rub it thoroughly with a microfiber cloth.

Dab some mineral oil on a cloth and rub the brass vigorously to remove the stain. This process can work in cooperation with the above methods, as well.
