Black appliances have the luxury of not showing dirt as much as white ones, but scratches can appear and mar the finish of a black microwave. Buffing out scratches as soon as they occur keeps the finish looking glossy and new. If left, the scratches may become deeper as dirt hides and grinds within the surface of the blemish. Remove scratches to keep your microwave looking up-to-date.
Mix 1 teaspoon of liquid dish soap into a sink of warm water.
Clean the outside of the microwave with the soapy water and a sponge. Rub aggressively over the scratches with the sponge to remove any buried dirt.
Rinse the microwave with a wet sponge. Dry it with a soft cloth.
Apply 1/2 teaspoon of car wax to the scratches on the microwave using a soft cloth. Rub the wax firmly into the scratches using small rotating motions. Continue rubbing until the wax begins to dry. Allow the wax to remain on the microwave until it becomes hazy.
Wipe the dried wax from the microwave with a clean soft cloth. Keep folding the cloth to expose a clean area as you remove the wax.
