Modern acrylic sinks have the appearance of porcelain, but are less porous and so are less subject to scratching and chipping. This makes them highly stain resistant. When discolouration does occur, it is generally easy to remove. Acrylic sinks come in a variety of colours. While white is the most popular choice, black has become increasingly popular as well.
The best prevention for staining is regular routine cleaning which prevents stain-causing materials from staying in prolonged contact with the surface.
Clean your acrylic sink after each use with a damp cloth and a small amount of ordinary dish-washing liquid. To give your kitchen a more polished appearance, dry the sink with a kitchen towel or paper towel.
If any discolouration does remain after routine cleaning, first try treating with a thin paste made from baking soda and water. Let the mixture sit for a few minutes and then scrub lightly with a non-abrasive nylon pad. If you like, you can boost the stain removal power of the baking soda by adding a small amount of borax powder to the mixture.
If any portion of the stain remains, treat it by laying a folded paper towel on the affected area. Soak the towel with a solution of diluted household bleach. Check the area every few minutes and remove the paper towel as soon as the stain has disappeared.
Rinse the sink thoroughly to remove any remaining traces of bleach.
Grease, oil or ink stains can most easily be removed by rubbing with a soft cloth soaked in rubbing alcohol.
Avoid placing hot pans in your acrylic sink as the material can melt and discolour from contact with heated metals. Generally speaking, though, acrylic sinks can withstand temperatures up to about 190 degrees C.
Abrasive powders and scouring pads should not be used on glossy surfaces. Mild abrasives can be used with caution on acrylic sinks featuring a matt surface when ordinary cleaning methods do not suffice. Other substances such as nail polish, nail polish remover, lacquer thinners or gasoline could damage the surface of your sink. In the unlikely event that your acrylic sink does become scratched from contact with a damaging substance or by cleaning with abrasive products, consult your local kitchen showroom for information on professional resurfacing.
