Tips

  • Move your piano to a sunny place if the ivory keys have yellowed; sunlight can help bleach them.

Common Mistakes to Avoid

1. Using harsh chemicals

Reason: Strong cleaners can damage the finish of the keys, leaving them dull or discolored.
Solution: Use only mild, piano-specific cleaners or a mixture of lukewarm water and mild dish soap.

2. Using excessive water

Reason: Soaking the keys can cause damage to the internal mechanisms of the piano.
Solution: Dampen a microfiber cloth slightly, rather than soaking it, and wipe the keys gently.

3. Ignoring stubborn stains

Reason: Delaying cleaning can allow stains to set, making them harder to remove.
Solution: Address stains promptly using a suitable cleaning solution and gently scrubbing with a soft cloth or brush.
