CARE AND CLEANING
DO NOT use abrasive or chemical cleaners (including chlorine bleach)
to clean Flushometers that may dull the luster and attack the chrome or
special decorative nishes. Use ONLY mild soap and water, then wipe dry
with clean cloth or towel. While cleaning the bathroom tile, protect the
Flushometer from any splattering of cleaner. Acids and cleaning uids will
discolor or remove chrome plating.
