How do I clean fingerprints and stains from my digital piano keyboard?
Use a soft, slightly damp cloth. Never use alcohol or harsh chemicals. Dry the keys immediately after cleaning.
Power off the piano before cleaning. Use a soft cloth that is slightly damp — not wet — to gently wipe the keys. Do not use alcohol, solvents, or harsh chemicals of any kind, as these can damage the key surface material.
Dry the keys immediately with a dry soft cloth after wiping. For stubborn stains, a cloth with a very small amount of mild soap and water can be used, followed by immediate drying.
Never allow moisture to drip into the gaps between the keys, as this can damage the key mechanism or internal components.
