A black acrylic sink makes a definite decorating statement. Glossy and stylish, the hard acrylic provides homeowners with an elegant yet impermeable work surface. This solid shell is soil resistant and impervious to stains; however, it will still need to be cleaned on a regular basis. Choosing the correct cleaning agents will take the work out of this chore and leave the sink streak-free and sparkling clean.
Fill the sink with hot water, and then add 1 cup of chlorine bleach. Allow the mixture to sit in the sink for one hour -- but no longer. The chlorine will kill any germs or bacteria that may be lurking on the surface of the sink while working to dissolve dirt, grime and sticky residue. Drain the water and rinse the sink thoroughly to remove any lingering traces of bleach. Wipe dry with a soft cloth. Always use bleach in a well-ventilated area, and never mix bleach with any other cleaning chemical, as it can cause a toxic gas.
Alternatively, distilled white vinegar can be used in place of chlorine bleach. The acetic acid in the vinegar will clean and disinfect the sink without harming the surface.
Scrubbing can help get rid of stains as well. Though, you don't want to scrub so hard you scratch the sink.
Pour 1 tsp. of mild, liquid dishwashing soap directly onto the surface of a damp sponge. Using the soapy sponge, gently wash the interior of the sink. Scrub any stubborn residue firmly, moving the sponge in small circles to loosen debris without scratching the acrylic. Rinse the sink with cold water and rub the clean surface with a soft towel to bring out the shine.
Remove stubborn stains with isopropyl alcohol. Pour 1 tbsp. of alcohol directly onto a soft, absorbent cloth and wipe the stain away. No need to rinse -- the alcohol will evaporate, leaving a clean, sparkling surface behind.
Do not use abrasive cleansers, steel wool pads or hard-bristled brushes to clean acrylic sinks. Acrylic is lightweight and durable, but it does tend to scratch. Should a scratch occur, fill in the abrasion with a light layer of automotive paste wax and buff with a soft cloth until the damage is no longer visible.
