DuPont CORIAN® Care And Maintenance Tips
CORIAN® was created for a lifetime of easy care.
Just follow the simple guidelines listed here to keep your CORIAN®
surfaces looking as fresh as they looked the day they were installed.
Also be sure to ask your dealer about the CORIAN® Care and Maintenance Video.
Routine Care
There are three types of countertop finishes: matte/satin, semi-gloss and high-gloss.* All CORIAN® sinks and bowls have the matte/satin 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. Follow the recommendations in the following charts to properly care for your finish type.
 
Preventing heat damage
CORIAN® withstands heat better than ordinary surface materials. However, hot pans, as well as some heat generating appliances, like frying pans or crockpots, can damage the surface. To prevent heat damage, always use a hot pad or a trivet with rubber feet to protect your CORIAN®
 
Removing cuts and scratches
Because the solid beauty of CORIAN® goes all the way through, CORIAN® surfaces are completely renewable. You can remove minor cuts and scratches yourself by following the instructions in the chart below.
 
REMOVING CUTS AND SCRATCHES
Finishes
Matte/Satin Semi-gloss High-gloss
Sand with 180- or 200-grit fine sand paper until cut is gone. Sand with 400-grit sandpaper. Sand with 400-grit sandpaper.
Restore finish with an abrasive cleanser and a green Scotch-Brite* pad. Restore finish with a non-abrasive cleanser and a white Scotch-Brite* pad. Wipe the surface and continue with 600-grit sandpaper.
Buff with white polishing compound and a low speed (1,500-2,000 rpm) polisher equipped with a wool pad. Finish with a countertop wax.

Preventing other damage
In most cases, CORIAN® can be repaired if accidentally damaged. However, be sure to follow the guidelines here 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 nail polish remover and flush with water.
  • Do not cut directly on CORIAN® countertops.
  • Run cold water when pouring boiling water into sinks.
