Why are my piano keys sticking?
The most common cause of sticky piano keys is the key slip being too close to the front of the white keys. Objects like coins and trash lodged underneath the keys, dirty rail pins, and broken hammer parts. Built up moisture also has a significant effect on keys sticking or moving fluidly.
How do you clean a sticky digital piano key?
Use a small amount of liquid soap with a damp cloth. Clean dirty keys with this cloth. Your grip must be firm but rubbing must be light. Gently rub keys until they are completely clean.
