solution of water and a mild neutral detergent. Be sure to wring all excess moisture from the

cloth before wiping.

Never use benzene, alcohol, thinner, or any other volatile agent for cleaning.

those for eyeglasses or camera lenses. When cleaning the lens, be very careful to avoid

scratching it.
