Corian® Care and Maintenance

Corian® Care and Maintenance

Corian® was created for a lifetime of easy care. Just follow the simple guidelines listed here to keep your Corian® surfaces looking as fresh as the day they were installed. Your care and maintenance kit will provide you with the tips and tools to help you enjoy your new Corian® top for years to come.

Corian Routine Care

Routine Care

Typically, three types of countertop finishes are used: matte/satin, semi-gloss and high-gloss*. Most countertops are finished with a matte/satin finish. All sinks have a matte finish. However, routine cleaning may raise the gloss level of the countertop over time. Soapy water, ammonia-based cleaners (not window cleaners) 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.

With over 100 colors and varying hues, some colors may appear to require more frequent cleaning to maintain their beauty. Darker colors tend to show fine scratches more easily and will require more attention than lighter colors. Over time through care and use your countertop will acquire a patina, changing the appearance of the finish. You may restore the look of the original finish by following the refurbishing guidelines on the next page.

*Contact your local Corian® sales expert if you are unsure of your finish.

Occasionally fill sink ¼ full with diluted household bleach (1 part water/1 part bleach).  Let stand for 15 minutes, and then wash sides and bottom as solution drains. 

Preventing Heat Damage

Preventing Heat Damage

Corian® is an excellent material for heat resistance. As with all countertop materials, it is important to minimize direct heat exposure to protect your surface and investment. We recommend using heat trivets or hot pads when placing hot objects on any surface. Allow cookware to cool before placing them into a Corian® sink.

Preventing Other Damage

Preventing Other Damage

In most cases Corian® can be repaired if accidentally damaged. However, be sure to follow the guidelines here to prevent any permanent damage to Corian®.

  • Avoid exposing Corian® to strong chemicals, such as paint removers, oven cleaners, etc. If contact occurs, quickly flush the surface with water.
  • Do not cut directly on Corian® countertops.
  • Boiling water alone will not damage your Corian® sink, however it’s a good practice to run your faucet while pouring boiling water into your sink.
Removing Minor Cuts and Scratches

Removing Minor Cuts and Scratches

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


  • Refer to sources for materials below to obtain abrasive pads mentioned here.
  • First, wash the area to remove any film that may clog the pads. Start with the Green pad. (Pad color from roughest to smoothest is: White, Yellow, Green, Peach, Lilac, Blue, Gray.) Rub over scratch in a straight line to remove it. Periodically switch rubbing direction 90°. Be sure all of the scratch is removed. If this first step takes too long, try the Yellow pad. To minimize dust during sanding, wet the surface. Rinse pad periodically to clean residue.
  • Clean top with water. Inspect to see if scratch was removed. If scratch remains repeat previous step. If scratch is gone, select next finer grit and repeat process. Rub over a larger area to blend in sanding.
  • Continue process using successively finer grits until the area blends closely with the surrounding surface gloss. Wash area to remove all sanding dust and residue. Rinse with clean water and wipe dry.
  • Rinse out all pads used and air dry before putting them away.
