Spot Resist™ Stainless and Spot Resist™ Brushed Nickel Finishes:
Moen recommends cleaning the Spot Resist finish with a mild soap, rinsing thoroughly with
warm water and drying with a clean, soft cloth. Never use cleaners containing abrasives (including
abrasive sponges or steel wool), ammonia, bleach or sodium hypochlorite, organic solvents (e.g. alco-
hols) or other harsh chemicals (e.g. lime scale removers) to clean the Spot Resist finish, as they may
damage the finish. Failure to comply with these cleaning instructions may void Moen's warranty.
