Keep your piano in tune. Your piano will sound its best and give you the most pleasure when it is tuned regularly and kept in proper playing condition.

Keep your piano clean. Keep the keyboard covered (except ivory keys) when not in use to prevent dust from accumulating. Clean the keys occasionally by wiping them with a damp cloth and drying them immediately. Do not use chemicals or solvents.

Maintain a fairly consistent temperature and humidity control in the room where your piano is located.

Play your piano regularly. You'll get the most enjoyment from it and will be able to identify detrimental conditions before they reach a critical state.

Keep all drinks and liquids off the piano. Once liquids are spilled, the damage is irreversible

Don't put anything on the music desk of a grand piano, except music.  Pencils, paper clips,  coins, and index cards can fall into the piano and cause problems

Use only a professional piano mover to move your piano. You will avoid injury to yourself, your instrument and your home.
