Care and Maintenance

The inherent qualities of Corian solid surfaces ensure the ultimate in easy care and renewability. Its nonporous, solid composition makes it easy to live and work with for many years.


Routine Care

Routine daily care and maintenance of Corian is easy. But, because cleaning practices differ around the world, please consult your local supplier of Corian for specific recommended care and maintenance practices and products. Use the following procedures as a guide to everyday care for Corian solid surfaces:

There are three types of countertop finishes: matte, semigloss and gloss.*
All Corian sinks have the matte finish.
Soapy water or ammonia-based cleaners will remove most dirt and stains from all types of finishes.
However, slightly different techniques must be used to remove difficult stains, depending on the finish. Please contact your source for Corian for more information.

*If you are uncertain about what finish you have, call your source for Corian.

Preventing Heat and Other Damage

Although Corian is quite resistant to heat, you should always use a hot pad or a trivet with rubber feet to protect Corian. Hot pans, as well as some heat-generating appliances like frying pans or electric cooking pots, can damage the surface if a hot pad or trivet is not used.


In most cases, Corian can be repaired if it is accidentally damaged. However, be sure to follow these guidelines 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. Remove nail polish with a non-acetone-based polish remover and flush with water. Do not cut directly on Corian countertops.

Removing Stains and Fixing Scratches or Burns

Nicks, scratches and cuts are inevitable with any high-use product, including Corian. But because Corian is solid all the way through, it is easy to renew to its original appearance as described below.

Minor damage, including scratches, general or chemical stains, scorches or burns, and minor impact marks, can be repaired on-site with a light abrasive cleanser and a product such as a Scotch-Brite* pad. For heavier damage, light sanding may be necessary. The following steps should be followed:

  • Identify the extent of the damage and ascertain whether a minor repair will solve the problem. You may want to consult with your supplier of Corian.
  • If the damage is minor, try to repair it with an abrasive cleanser or a product such as a Scotch-Brite* pad.
  • If the above step is unsuccessful, hand-sand with 400-grit wet and dry paper. To minimize dust, wet the surface before starting.
  • If this is unsuccessful, use an electric sander and heavier-grit paper. Always make provisions to control dust.
  • If this, too, is unsuccessful, you may need to consult a professional for other repair options. In this case, contact your supplier of Corian for assistance.

Renewing Corian

Nicks. Stains. Cuts. Scratches. While these can permanently mar most other surfaces, they won't compromise the appearance of Corian solid surfaces. That's because it's easy to restore Corian to its original state, using an ordinary abrasive cleanser and a cleansing pad such as a green Scotch-Brite* pad. And, if damage does occur, Corian can be repaired on site, saving both downtime and aggravation.

If it's specifically coffee, you might try "Squeak n' Clean" or equivalent. Linens and Things, Bed and Bath maybe even your grocery might have a specific cleaner for coffeepots that could be tried.

Coffee Stains on Beige Corian Sink

Coffee stains on beige corian sinks can be removed fast and easy with a product called "Bar Keeper's Friend." It's found in the cleaning aisle and is along the lines of a Comet or Ajax cleanser, but oh, so much better. It's my favorite household product. How do I know this works on a Corian (beige) sink? I too have a Corian beige sink. Blessings. (08/04/2008)

If you are certain the sink is Dupont Corian, we recommend Clorox Cleanup with Bleach. You can also dilute household bleach by adding a couple capfuls of bleach to your filled sink. Once the sink is filled with this solution, you can use a Scotchbrite pad (the green one on the back of a sponge) and lightly buff out the stains. We do not recommend this for the surface of the tops as you may scratch the surface if you use too much force with the ScotchBrite pad. (10/08/2008)
