speakers have a painted surface, clean with a soft damp cloth. If necessary, use
a mild detergent such as dish soap. If the speakers have a wood veneer finish, clean them
with wood furniture polish. You may vacuum the speaker grille panels carefully, if necessary.
Do not use any sprays near the system. Do not use any solvents, chemicals, or cleaning
solutions containing alcohol, ammonia, or abrasives. Do not allow liquids to spill into any
openings.
