Dupont Corian

Cleaning- All Finishes:

Most dirt & residue:
  • Use soapy water, ammonia based cleaner (not window cleaner), rinse and wipe completely dry. Commercially available solid surface cleaners, such as Clean EnCounters® will also work well.

Preventing hard water marks:
  • Rinse and wipe completely dry after cleaning; clean up spills before they dry.

Removing hard water marks:
  • Use a cleaner formulated for removing hard water marks such as CLR or Lime-A-Way.

Difficult residue:

  • Spray residue with Deep Cleaner for DuPont Corian® from Stone Care International. Follow instructions on the bottle. Wash area with soapy water, rinse and wipe completely dry. If residue persists, follow steps below for removing dulling film.

  • Occasionally, wipe surface with diluted household bleach (1 part water/1 part bleach). Rinse top thoroughly with water and wipe completely dry.

Sinks & Lavatories:

  • Follow procedures above or use Soft Scrub® and a green Scotch-Brite® pad to remove residue. Rub green Scotch-Brite® over entire sink to blend in finish. Note: Do not use Scotch-Brite® on countertop surface.

  • Fill your sink ¼ full with diluted household bleach (1 part water/1 part bleach). Be sure to get some of the solution into the overflow opening to disinfect. Let the solution stay in the sink for 15 minutes; then wash sides and bottom as solution drains. Rinse out the sink with water.

Preventing Heat Damage:
While Corian® is heat resistant, as with all countertop materials, it is important to minimize direct heat exposure to protect your surface and investment.


Always use heat trivets or hot pads when placing hot objects on any surface. Always use a trivet under portable heat generating appliances such as a toaster oven. Allow cookware to cool before placing it into a Corian® sink.

Preventing Other Damage:
In most cases Corian® can be repaired if damaged. Be sure to follow these guidelines to help you prevent any permanent damage to your Corian®.

Avoid getting strong chemicals, such as paint removers, oven cleaners, etc., on your Corian® countertop. If a spill does occur, promptly flush the surface with water to fully rinse off the chemical.

Do not cut directly on Corian® countertops. Use a cutting board.

Boiling water alone will not damage your Corian® sink, however, it is a recommended practice to run cold water from the faucet while pouring boiling water into the sink.
