The Don’ts of Cleaning

  • Do NOT use a chemical cleaner or polish. They are too harsh and will cause damage. Stick to mild soaps if possible.
  • Do NOT use paper towels to wipe the keys. You will need to use a lint-free cloth that leaves no residue behind.
  • Do NOT wipe your keys from side to side as moisture can get in between them and cause damage.
  • Do NOT use the same cloth for black keys and white keys. Sometimes paint from the black keys can transfer onto the white ones.
  • Do NOT use spray-on disinfectants as these can destroy the surfaces of both ivory keys and plastic keys as well as causing harm to the rest of the piano.

Clean Each Key Carefully

Before you starting cleaning the keys properly take a dry cloth and give each key a wipe so that any dust sitting there is removed. You may also use a soft-bristled brush or a duster.

If you want to disinfect your keys then you can use a solution of water and white vinegar to wipe down the keys. Take a cheesecloth or flannel and wipe the key vertically downwards, letting the keys dry in between each wipe. Remember to change your cloth between the white and black keys. This solution is the best way to clean plastic keys. Only use a little bit, one part vinegar to four parts warm water so that the acid doesn’t cause damage.

For piano ivory keys make sure to use a mild solution of warm water and a small amount of dish soap. The damp cloth will be sufficient enough to clean the keys. Use a gentle brushing motion and never scrub as this could damage ivory keys.

Whiten Ivory Keys

White toothpaste is a great way to clean ivory keys. Make sure it’s plain white toothpaste with no color in it. Gel toothpaste will corrode ivory. If you are finding that your ivory keys are discoloring quite often then you may want to consider moving the instrument away from direct sunlight because this can cause the keys to bleach.

Another way to whiten ivory keys is a little unconventional. You may want to apply mayonnaise or yogurt using a cloth to the keys and wipe them down. The bacteria present in these foods will bleach the ivory in a gentle way that is effective to get them looking white again. Just remember to buff each key afterward using a dry cloth so that any food residue is removed.

Ready to Play

It’s a good idea to disinfect your keys once every few weeks and to clean them at least once a month to keep your instrument looking and sounding great. If you don’t use your piano that much then you can leave longer gaps between cleaning, giving it a light dusting with a brush or damp cloth once every few weeks. You can take great care of your keys if you wash your hands before playing as this removes the oil from your fingers that causes the keys to discolor.

If you have a piano teacher then they may be able to give you advice and best practices for cleaning your specific piano type. You can ask them about how frequently you should be cleaning them as well as the best technique to clean your key material.
