How to Safely Clean Ivory and Plastic Piano Keys

Using the wrong cleaning products can permanently ruin your piano keys. Learn the safest methods to remove dirt and grime from ivory and plastic.

Over time, piano keys accumulate dirt, oils from our fingers, and dust. However, reaching for standard household glass cleaners or bleach is a huge mistake. Harsh chemicals can melt plastic keytops or permanently warp and discolor genuine ivory keys. The safest way to clean plastic keys is with a soft, lint-free cloth slightly dampened with a very mild solution of water and a drop of dish soap. Wipe the keys gently toward you (never side-to-side, which pushes dirt between the keys), and immediately dry them with a separate microfiber cloth. For older pianos with genuine ivory keys, water is the enemy. Ivory is highly porous and will absorb moisture, leading to warping and detaching. Use a white vinyl eraser to gently rub away surface stains, or consult a professional piano technician for safe ivory polishing and whitening services.
