Wipe the high-gloss black finish with a dry, lint-free cloth. Start at the top and wipe in a sweeping motion while moving down. This will remove any surface dust or debris on the glossy finish.
Fill a container with 1 cup of distilled water and 1 cup of white vinegar. Pour the diluted vinegar mixture carefully into a clean spray bottle.
Mist a clean lint-free cloth with the diluted vinegar. Start at the top of the high-gloss black, and wipe in a sweeping motion over the surface. The white vinegar will clean the surface while cutting through grease, grime and hard-water spots.
Reapply the diluted vinegar to the cloth when it becomes dry and continue wiping the high-gloss black while moving down toward the bottom.
Buff the high-gloss black dry with a clean, lint-free cloth. Repeat the process as needed.
