Acrylic sinks are lovely to look at and hold up well to most everyday use. The color goes all the way through, thus resisting staining, so they seldom need more than a casual wipe down to keep them looking good. To prevent discoloration or scratches that may dull the surface, avoid heat and never use scouring pads or powders to clean. You can polish out light scratches with acrylic buffing compounds, but a seriously damaged surface requires restoration by a pro. As with most things, following a good maintenance routine will prolong the shine and head off costly repairs.
Dampen a soft cloth with warm water and apply a bit of liquid dishwashing detergent to the cloth.
Scrub the sink all over with the soapy cloth using small circular motions. Avoid wiping in broad irregular strokes that may leave streaks.
Rinse the sink well with cold water.
Dry, and then polish the sink with a soft dry cloth and acrylic sink polishing compound -- following product recommendations for use -- to bring out the shine.
Removing Coffee, Tea or Other Stains
Dilute ordinary household bleach to a ratio of about 1 tbsp. to 1/4 cup water.
Dip a cloth in the bleach solution and press it over the spot like a poultice for a few minutes. Do not leave the bleach on the sink long as strong chemicals like bleach – even diluted -- may damage or dull the surface. Consult the manufacturer's recommendations if you are unsure whether bleach is safe for your sink.
Wash the sink as previously described.
Rinse the sink very well with cold water to remove all traces of soap and bleach.
Dry and buff the sink as before.
