General cleaning instructions
For general cleaning, a lint-free cloth dampened with distilled water is recommended. After cleaning, let
the cleaned par

Do not spray fluids directly onto the product. Spray the fluid onto the cloth used for cleaning.
To remove stubborn dirt or stains, moisten a soft cloth with water and a neutral detergent, or a general-
purpose industrial cleaner (such as the Simple Green industrial cleaner). Remove any remaining soap
foam with a dry cloth.
For glass surfaces, use a soft, lint-free cloth lightly moistened with a non-abrasive glass cleaner or with
a general-purpose glass cleaner (such as the Simple Green glass cleaner). Remove any remaining soap
foam with a lint-free cloth dampened with distilled water, and dry it with a dry cloth to prevent spotting.
WARNING! Make sure to use adequate personal protective equipment. See Personal protective
equipment on page 14 and Warning labels on page 15.
