Corian© Care & Maintenance
CORIAN IS A LIFETIME MATERIAL SINCE YOU CARE AND MAINTAIN IT!
Corian® solid surfaces meet the demanding needs of today’s commercial surfacing applications. As a solid, non-porous
surface, like Corian®, it can be maintained with minimum care to retain the original appearance. Because it can be repaired, Corian® will
still look and perform like a new installation, while other surfacing materials will often need to be replaced. With proper care the
CCorian® surfaces in your commercial / residential building will stay looking like new.
Routine Care
Our type of Corian® Solid Surface finish is matte/satin. Soapy water, ammonia-based cleaners or commercially available solid surface
cleaners will remove most dirt and residue from all types of finishes. Stubborn residue will require a little stronger cleaner. Follow
the recommendations below to properly clean your Corian® Solid Surface.
Conventional Cleaning Techniques
* Washing with soap and water is usually sufficient to remove surface dirt or stains.
* Ammonia based liquid cleaner (not window cleaner) may also be used. Always rinse surface thoroughly and wipe dry.
* Drying is an important step, preventing a build-up of soap film or cleaning residue, which can
create the appearance of light scratches over time.
* Stubborn soap film or cleaning residue build-up on Corian® is easily removed with abrasive cleanser
and a white Scotch-Brite® pad or a sponge.
* For darker colors, a polish may be used to enhance the shine. For areas where there may be food contact, always use a polish
formulated for food contact areas, such as Countertop Magic®. Where food contact is not a possibility, a simple furniture polish
may be used. Always follow the manufacturer’s instructions for using the polish and for safety concerns.
Cleaning Agents
Corian® is unaffected by common household and commercial cleaners such as:
* Powdered abrasive cleansers (like Comet®)
* Ammonia
* Strong detergents
* Oxalic acid solutions
* Dilute hydrochloric acid solutions
* Dilute trisodium phosphate solutions
Acid drain cleaners may cause surface damage and should not be used on Corian® solid surfaces.
Preventing Damage
Cigarette Burns, Stubborn Stains
Unlike other surface materials stains or marks caused by cigarettes, alcohol, food, lipstick, hair dye, shoe polish, iodine, marking
pens, etc. can be removed by using an abrasive cleanser and a green Scotch-Brite® pad.
This type of maintenance will not harm the Corian® surface, and will restore it to “like new” condition.
Repairs
Surfaces of Corian® can be repaired with no permanent damage. Tough to remove stains, fine scratches, and small cuts can be
removed using standard repair techniques.
Making your own repairs
* To restore a matte finish - use 220 grit sandpaper followed by hard buffing with a green Scotch-Brite® pad in a circular motion.
* To restore a semi-gloss - use the 220 grit sandpaper, followed by 320 grit, followed by 400 grit. Then blend the finish in by using
abrasive cleanser and a sponge or rag.
* A high gloss finish is best restored by a professional. Contact your supplier or DuPont.
* If the damage is particularly deep, use a random orbital sander equipped with vacuum dust collection. Start with 120 grit
sandpaper first, followed by 180-220 grit. After sanding, a uniform matte finish can be obtained by buffing with a green
Scotch-Brite® buffing pad. For a semi-gloss, continue sanding with 320 followed by 400 grit. Then buff with a gray Scotch-Brite® pad.
The impact resistance of Corian® allows it to withstand harsh use without chipping, breaking, or cracking. However, if damaged due
to extreme abuse, satisfactory repairs can often be made. Contact us for guidance.
Preventing Damage
Avoid Strong Chemicals / Some chemicals are not compatible with Corian®. Avoid surface contact with:
* Strong chlorinated solvents
* Chloroform
* Ketones
* Methylene chloride (paint removers)
* Very strong acids such as concentrated sulfuric and hydrochloric acids
* Acid drain cleaners should not be used.
Surfaces exposed to these agents should be promptly flushed with water. Contact for even a short period of time can cause surface
damage, spots, or staining. Follow the recommended repair procedures described above as needed to repair and/or restore the
surface to its original condition. Severe damage caused by incompatible chemical contact will require professional repair.
