Cleaning Fiberglass Sinks and Tubs
Use non-abrasive cleaners such as:
-hand dishwashing liquids or liquid laundry detergents
-household all-purpose cleaners or bathroom cleaners
(i.e. "409", "Dow Bathroom Cleaner", etc.)
-mild to moderate alkali solutions (i.e. baking soda in
warm water, trisodium phosphate in warm water
-(1 tablespoon per gallon, "Spic & Span" solution which
contains trisodium phosphate, etc.)
-baking soda moistened with water to a paste; wet
surface of tub or stall; gently rub with the paste on a
sponge, or soft nylon brush.
Apply all cleaners with a sponge or non-abrasive
applicator made of nylon, polyester, or polyethylene.
Always rinse thoroughly to remove all cleaner.
Never use any abrasive cleaner like common scouring
powders, nor any abrasive scouring pads, steel wool,
and paper, or scrapers.
