Cleaning
For general cleaning, wipe the 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, rinse with water, 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 re-formation of the chromium oxide layer.
DO NOT use steel wool, sandpaper, mineral acids, bleaches, or chlorine cleansers on the stainless steel.
