12. Cleaning Tips for Guardian Telephones
Guardian Telephones may occasionally need to be cleaned to maintain appearance. Generally, wiping the surface
with a clean, water dampened cloth will remove most films or residues. If the soiling is too stubborn for plain water, a
mild detergent solution may be used. Be sure to wipe away any detergent residue with a plain water dampened
cloth. The Telephone may be cleaned with any general-purpose household glass and surface type cleaner. Do not
spray the telephone directly! Spray the cleaner on a soft cloth then wipe the surface. Pre-treated cloths, like those
used for eyeglasses or cameras, may be used to clean the Telephone. Premoistened towelettes may also be used,
however, avoid those containing lanolin or aloe as they will leave a slippery residue. The handset and surface of the
telephone may be cleaned with disinfectants used for general cleaning in a medical environment. Isopropyl alcohol
may be used applied with a cloth. Avoid using alcohol on silicon based keypads, since doing so may significantly
degrade legibility.
Do not use furniture polishes, waxes or plasticizer-based cleaner (Armor All etc.)
Do not use lanolin, aloe, glycerin or other skin care type products.
Do not apply any solvent such as acetone, mineral spirits etc.
Do not directly spray or immerse the handset.
