Cleaning your Piano Keys:
There are 88 piano keys
on a standard grand piano. Each one of those keys are covered by a piece of plastic or ivory called a keytop. Although some notes may get more of a workout then others, they all can use a good cleaning now and than. But what is the best way to remove the dirt, grime and oil that can accumulate?
The first thing you will need to do is determine what material your piano keys are made out of. Due to the ban on the use of newly harvested ivory, the vast majority of pianos played and manufactured today have some type of plastic or high quality simulated ivory keytop. Although the feel of ivory is not always fully duplicated, they are usually more durable and easier to clean.
If your keytops are plastic, use a clean white cloth with a bit of mild soap or key cleaner to remove the grime. After applying the cleaning solution to the cloth itself, wipe the keys down with a back to front motion, not side to side. Clean a few keys at a time and then dry with another cloth. Be careful not to use a colored cloth as the color could bleed onto the keys. Be sure to also take care to not get the cleaning solution on the wooden piano keys themselves. The wood can absorb the moisture, causing swelling or separation.
