DuPont describes its Corian countertops as providing a "renewable" surface. Indeed if you have dropped a hard object like a glass or a Dutch oven that leaves a minor scratch or abrasion, repairing your Corian countertop takes little time or effort. By doing some light sanding or using some mild abrasive liquid cleaner, the blemishes disappear in 15 minutes or less, and your countertop regains the appearance it had on the day it was installed.

Repair your Corian countertop by lightly sanding any minor abrasions.

Step 1

Clean the countertop area that you want to repair with a sponge dampened with warm water. Put a 180- or 220-grit fine sandpaper on a sanding block when dealing with cuts and scratches on matte or satin Corian finish. Use 400-grit sandpaper on semi-gloss or high-gloss surfaces.

Step 2

Sand lightly in a circular fashion until the blemishes are gone. Wipe away the dust with a damp sponge. Apply a mild liquid abrasive cleaner over a slightly larger area, blending the sanded area with the rest of your countertop.

Step 3

Use a low-speed polisher to rub in white polishing compound on high-gloss surfaces. Complete the repair by putting a clean wool pad on your polisher and applying a countertop wax to the surface.
