Preventive Maintenance for Models 277-001/-002BH/-002BHAC
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 the Model 277-001 telephone.
Cleaning
•
For general cleaning, wipe the surface with a cleanser or a 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
magnesium oxide, ammonia, and water paste. 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 natural reformation of the chromium oxide layer.
Do NOT use steel wool, sandpaper, mineral acids, bleaches, or chlorine cleansers on the stainless
surface.
