Corian countertops are a solid surface countertop, sort of like a mix of laminate and stone countertops. Unlike laminate countertops, Corian countertops have the same look all the way through, so it's possible to refinish them should they get stained or scratched. Some stains can be removed with a little scrubbing, while other stains or scratches may make it so the countertop needs to be refinished by sanding it. Those who don't know how to refinish Corian countertops or don't want to take the time and effort to do it themselves can hire a professional to do the job, but the job isn't that complicated.

Cleaning Water Spots or Blotches

If water isn't wiped up right away, it can leave spots or blotches. Usually all it takes to remove these is a little elbow grease, cleaner and a sponge.

  1. Rub a mild abrasive cleanser over the spots with a damp rag or sponge. Move the cloth over the counter in small circles, starting in the front and moving toward the back from one side to the other until the whole area is cleaned. Lysol spray or an ammonia-based window cleaner may also work for this purpose.
  2. If this doesn't remove the splotches, you can try a more abrasive cleaner, such as Comet or Ajax, but you'll have to wash the counter multiple times afterward to remove the residue these cleaners will leave behind.
  3. Rinse off the cleanser with water and then dry the countertop.

Refinishing to Removing Scratches

A mild cleaner may not remove all scratches; this usually takes a few more steps. You can purchase special abrasive pads that are color coded for removing scratches from Corian countertops, in which case you use the peach pad, followed by the aqua and gray pads, if needed, to get the counter to the level of gloss you want. Otherwise, you can use more common household items as follows:

  1. In some cases, the green scratchy side of an abrasive pad may be enough to get rid of scratches. Rub lightly in the same direction as the scratch, then in the opposite direction.
  2. Clean off the dust on the counter and the pad.
  3. If the pad doesn't do the job, try using 800-grit sandpaper, followed by 1,000-grit sandpaper. Wet the countertop before sanding and wet it periodically as you go.
  4. Once the scratches have been removed, rinse the counter off with clean water and dry it.
  5. Rubbing a sponge over the entire counter after sanding can help restore a matte finish, while a sander fitted with finishing pads used with polishing paste will be necessary to give the counter a glossy finish.
  6. When you're all finished, use of mix of half water and half bleach to disinfect the counter, then rinse it off with water and dry it thoroughly.
