Corian Care & Maintenance

Most countertops are finished with a matte/satin finish. All Corian® sinks have a matte/satin finish. Soapy water, ammonia based cleaners (not window cleaners as they can leave a waxy build up that may dull the surface) or commercially available solid surface cleaners will remove most dirt and residue from all types of finishes. Stubborn residue will require a little stronger cleaner. Follow the recommendations below to properly clean your countertop and sink:

Most Dirt & Residue Use soapy water, ammonia based cleaner (not window cleaner), rinse and wipe completely dry. Commercially available solid surface cleaners will also work well.
Preventing Hard Water Marks Rinse and wipe completely dry after cleaning; clean up spills before they dry.
Removing Hard Water Marks Use a cleaner fomulated for removing hard water marks such as CLR or Lime-A-Way.
Difficult Residue Spray residue with Deep Cleaner for DuPont Corian® from Stone Care International. Follow instructions on the bottle. Wash area with soapy water, rinse and wipe completely dry. If residue persists, follow steps below for removing dulling film.
Disinfecting Occasionally, wipe surface with diluted household bleach* (1 part water / 1 part bleach). Rinse top thoroughly with water and wipe completely dry.

*Avoid getting the bleach solution in your eyes or bare skin. Always follow the bleach manufacturer’s safety instructions when working with bleach.



While Corian® is heat resistant, as with all countertop materials, it is important to minimize direct heat exposure to protect your surface and investment.

DO NOT PLACE HOT POTS, PANS, ETC. DIRECTLY ON THE COUNTERTOP SURFACE

Always use heat trivets or hot pads when placing hot objects on any surface. Always use a trivet under portable heat generating appliances such as a toaster oven. Allow cookware to cool before placing it into a Corian® sink.



In most cases Corian® can be repaired if damaged. Be sure to follow these guidelines to help you prevent any permanent damage to your Corian®.

Avoid getting strong chemicals, such as paint removers, oven cleaners, etc., on your Corian® countertop. If a spill does occur, promptly flush the surface with water to fully rinse off the chemical.

Do not cut directly on Corian® countertops. Use a cutting board. Boiling water alone will not damage your Corian® sink, however it is a recommended practice to run cold water from the faucet while pouring boiling water into the sink.



You may notice that the surface of your countertop begins to look blotchy. Typically, this is caused by leaving hard water to dry on the surface which will leave a film of minerals.

To remove this film: Pour some mild abrasive liquid cleanser, such as Soft Scrub®, on a damp sponge or cloth and rub over area using small circular motions, from the front to the back, then side to side, overlapping the circles until the entire area has been cleaned. Thoroughly rinse the top with clean water and WIPE SURFACE COMPLETELY DRY. Check to see if blotchiness is gone. If not, repeat procedure applying more pressure on the sponge or rag. Continue over all affected areas until all film is removed.

NOTE: While this procedure may remove or minimize the look of very fine scratches, other deeper scratches may remain.



Because the solid beauty of Corian® goes all the way through, Corian® surfaces are renewable. You can remove minor cuts and scratches yourself by following these instructions.

First, wash the area where the scratch is located, following the instructions found in this guide, to remove any film on the surface as this film may clog the abrasive pads. With this surface still wet, start rubbing with the Peach colored side of the cleaning pad. Use a light touch. Pressing too hard may actually leave deeper scratches. Rub over the scratch using a straight line motion. Periodically switch rubbing direction ninety degrees. Rinse pad periodically during this process to remove any built up residue. Be sure all of the scratch is removed.

Clean top with water and dry thoroughly. Check to see if sanded area blends with rest of the top. Please note that sanded area may not perfectly match remainder of top. If necessary, turn pad over and repeat process. Rub over large area to blend in sanding.

If needed, continue the sanding process using the Aqua colored pad and if necessary, the Gray colored pad, until the desired gloss level is achieved. Rinse out all pads used and allow them to air dry before putting them away.
