Cleaning a Corian Countertop

A solid surface composed of alumina trihydrate and acrylic polymer, Corian is a registered trademark of the DuPont Company. First manufactured in 1967 and primarily used for countertops, Corian is available in many colors, thicknesses, and solid surfaces.

When we think of countertops, most of us think of kitchens. However, Corian is also used in the manufacture of bathroom and workspace countertops, and comes in three standard finishes of matte/satin, semi-gloss, and high-gloss. Although it can look like real granite, Corian is a synthetic material and requires special care when cleaning it. Corian is tough and holds up well under everyday use, but there are a few rules to follow when cleaning your Corian countertops, with each of the three finishes requiring different cleaning methods:

• Clean matte finished countertops with soapy water and a sponge. For stubborn food stains, DuPont recommends using Soft Scrub with a green Scotch-Brite scouring pad only in sinks, but never on countertops. Disinfect the countertop with a mild solution of water and bleach, or commercial disinfectants safe for created countertops.
• Semi-gloss Corian countertops may be cleaned following the same instructions as for the matte finish, except take care not to use abrasive cleaners so you won't scratch the surface of the countertop. Use a countertop polish such as Enhance Countertop Polish, and then buff the surface to a gleaming shine after cleaning.
• Use a mild polish on high-gloss Corian countertops to maintain their gloss. Use solid surface cleaners available under several brand names on Corian countertops, and then follow up with a countertop polish such as Countertop Magic.

The most important thing to remember when cleaning any finish of Corian countertops is to wipe the surface completely dry after cleaning.

To prevent your Corian countertops from being damaged, follow these simple rules:

• Do not cut directly on the surface.
• Do not place hot dishes, pots, or pans directly onto the surface.
• Do not drop heavy items onto the countertop.
• Do not use abrasive cleansers or scouring pads on the surface.

DuPont provides a warranty with their Corian countertops, but that warranty will be void if you use cleaners and polishes not specifically recommended by them, or if you do not ensure against damage to the countertops. DuPont provides manufacturers cleaning and routine care instructions when you have Corian countertops installed. Follow those instructions and contact the manufacturer if in doubt.
