solutions, alkaline cleaning solutions, abrasive cleaning
agents, or chemically-treated wipes that may damage
the surfaces for cleaning or disinfection.
• Do not wipe with force using a cloth that may have dust
or other particles adhering to it. Doing so may scratch
the surfaces.

extended period of time. Doing so may cause surface
deterioration or cause the surface to peel.
