How to Restore Corian Countertops. Corian is a brand name material DuPont manufactures. It is used for countertops in kitchens and bathrooms, comes in many different colors and is known for its durability. You can adapt it for many uses and design scenarios. Restore your Corian to its original beauty with these steps.
Look over the countertop. Examine scratches, cuts and burns. Determine if they are surface scratches or deeper scratches.
Wash countertops in the area that has normal surface scratches. Use a light, abrasive cleanser and a non-scratch pad such as Scotch-Brite. Use light circular motions, and then rinse off with a damp cloth. Apply pressure only lightly.
Restore with a 400-grit sandpaper on a wet surface when the cleanser doesn't get all surface scratches with light pressure only.
Use slightly heavier grit sandpaper and a small electric sander on Corian countertops to restore deeper cuts and burns.
Check the sanded area to make sure the edges of the area where you have sanded blend in with the rest of the countertop. Lightly sand the edges, if necessary.
Contact a company that is certified in Corian restoration. It has special equipment and products, if your do-it-yourself project doesn't produce results.
