Black shoe polish stains are easily visible on a clean white carpet. The stains can occur when you wipe newly polished shoes on the carpet or spill the polish. The stains can be more difficult to remove from white carpet than from darker carpet because they are more visible. The easiest way to get black shoe polish out of white carpet is with dry cleaning solvent and a homemade soap solution.
Scrape as much of the solid shoe polish as possible off the carpet using a spoon. Do not push the shoe polish into the pile or rub the polish with the spoon.
Dampen a clean sponge with dry cleaning solvent. Blot the stain with the sponge without rubbing, then blot with a clean white towel to soak up the liquid.
Combine one tbsp of liquid dish soap, one tbsp of ammonia and two cups of warm water in a bowl. Dampen a white cloth and blot the remaining stain. Turn the cloth to a clean spot every four to five blots. Continue blotting with the solution until the stain is not present.
Dampen a clean white cloth with cold water and blot the stain to rinse. Hold a clean section of the white towel over the wet spot and blot to dry.
