Piano--Care and Cleaning
Care
Avoid extremes in humidity if possible, as excessive
dampness or dryness is damaging. Sudden changes in
temperature affect both the tone and the wood. Do not put
near a register, radiator or window. Have it tuned
regularly.
Cleaning
Follow manufacturer's instructions for cleaning. The
lacquer finish on the wood only needs to be dusted with a
vacuum cleaner brush, and sometimes wiped with a soft,
untreated dusting cloth or paper towel. It may not
require waxing. Vacuum the keyboard.
If waxing of wood finish is desired, use a wax or
polish to give the desired amount of gloss. Old ivory
keys yellow with age which is natural and cannot be
changed; clean them with a cloth barely moistened with
denatured alcohol as too much moisture loosens the keys;
never use soap which stains ivory. Modern keys are made
of plastic (usually acrylic) and may be wiped with a damp
cloth, followed by a dry cloth. Follow manufacturer's
instructions in guide with piano.
For stubborn soil, wipe keys with a cloth wrung out of
mild detergent and water solution; wipe with damp cloth;
dry with dry cloth.
