Care and Maintenance of a Piano
Care You Can Do at Home
Keep Your Piano Clean at All Times
What kind of care is required?
To protect your piano from dust or dirt, keep clean the surface of the finish always.
Finishes
Lightly brush off surface dust using a piano feather duster or soft cloth.
Before using piano wax or polish, consult with the store where you purchased the piano, or a specialty piano store. Depending on the piano model, some types or brands of wax and polish may not be acceptable.
Avoid using chemical-impregnanted wipes or cleaning agents which are not designed for piano because their chemical compositions may not suit for piano's finish.
Keyboard
Wipe gently using a soft cloth (use separate clothes to wipe down keyboard and piano finishes).
When dirt is noticeable, dampen a cloth in a dilute solution of a neutral detergent, wring out well, and use this cloth to wipe away the dirt.
Never use any kind of alcohol such as rubbing alcohol or denatured alcohol because it can cause cracking.
Generally speaking, the best thing to do is to refrain from playing with dirty hands.
