Preventive Maintenance for Models 297-70x and 298-70x
Stainless steel does require maintenance to prevent corrosion from occurring. Different installation
locations may require more regular maintenance than others, depending on the environment and exposure
to airborne contaminants. The following maintenance steps should be performed on a regular basis or
when corrosion is first noticed on your Model 297-70x and 298-70x Telephones.
Cleaning
For general cleaning, wipe surface with a cleanser or cleanser and water mixture. Any cleanser that is
safe for glass is usually safe for stainless steel. Wipe dry.
If corrosion or rusting is noticed, remove with a non-abrasive commercial cleanser and water. Rub
stained areas in the same direction as the existing grain. Stubborn stains may be removed with a paste
made from magnesium oxide, ammonia, and water. Wipe clean with water rinse and dry.
Prevention
Automotive wax provides the best results in preventing corrosion on stainless steel. Simply apply wax,
let dry to a haze, and buff to a shine with a clean dry cloth. This application should protect the telephone
surface for many months as it will allow naturally re-formation of the chromium oxide layer.
DO NOT use steel wool, sandpaper, mineral acids, bleaches, or chlorine cleansers on the stainless steel.
