How to look after an old piano

Position it away from any radiators.

Keep the lid closed to stop dust getting in the works. If the keys are ivory, they naturally yellow over time; newer keys will be plastic.

Either way, wipe clean with a just-damp chamois leather.

Remove any dust from inside the casing with a vacuum, or blow out with a hairdryer set at cool.

Finally, the best way to keep a piano in nice condition is to play it!
