Design Your Dream Countertops

Routine Maintenance of Your Corian® Countertop

All Corian® sinks are finished in either a matte or satin style. Soapy water,

ammonia based cleaners or other commercially available and solid surface specific cleaners will remove most of the dirt and residue that can accrue on your counters from all types of finishes. Certain stubborn residues will require a slightly stronger cleaner.

NOTE: Do not use window cleaners as they can leave a waxy build up that may dull the surface!!

Follow our recommendations below to learn how to care for Corian® countertops and sinks:


Common Dirt & Residue Use soapy water along with ammonia based cleaner (not window cleaner). Then rinse the surface and wipe it completely dry. Solid surface cleaners that are commercially available will also work effectively.
Preventing Hard Water Marks It is important to rinse and wipe the surface completely dry after cleaning it. You should also clean up spills immediately and before they get a chance to dry.
Removing Hard Water Marks If hard water marks do occur, we recommend that you use a cleaner specially formulated for the removal of hard water marks like CLR or Lime-A-Way.
Dealing With Difficult Residue Spray the residue with a Deep Cleaner made for DuPont Corian® from Stone Care International. Then follow the specific instructions on the bottle. You should then wash the area with soapy water, rinse and then wipe completely dry. If the residue persists, we recommend that you follow steps listed below for removing dulling film.
Disinfecting It is considered good practice to occasionally wipe the surface of your countertop with diluted household bleach. This is done by combining1 part water with 1 part bleach. Then rinse the solution off the surface top thoroughly with warm water and then wipe it completely dry.


Cleaning Follow the procedures that are listed above or simply use Soft Scrub® along side a green Scotch-Brite® pad to remove residues. Rub the green Scotch-Brite® pad on the entire surface of the sink to blend in its finish. NOTE: Do Not use the Scotch-Brite® on the countertop surface as it could scratch and mar its finish.
Disinfecting Fill your sink one quarter full with diluted household bleach, made up of 1 part water and 1 part bleach. Make sure that you get some of the bleach solution inside the overflow opening to disinfect it. Let the solution stay inside the sink for at least 15 minutes; then wash the sides and the bottom of the sink as the solution drains. Then rinse out the entire sink with warm water.

NOTE: Avoid letting the bleach solution contact your eyes and/or bare skin. You should always follow the strict bleach manufacturer’s safety instructions when dealing with the solution to avoid injury.

Preventing Heat Damage

When learning how to care for Corian® countertops, you should take special note of preventing heat damage. While Corian® is a heat resistant surface, as with all countertop materials, it is vital that you minimize all direct heat exposure to the surface in order to protect your investment.


It is recommended that you always use a heat trivet or hot pad when you place hot objects on any part of the countertops surface. As you learn how to care for Corian®, you should also always remember to use a trivet underneath portable heat-generating appliances like toaster ovens and also remember to allow all cookware to completely cool before placing it inside a Corian® sink.

Preventing Other Types Of Damage

In most cases, ifCorian®  is damaged, it can be repaired. However, we recommend that you follow these guidelines in order to help you prevent permanent damage to your Corian® countertops.

Another important note when learning how to care for Corian® Countertops is to avoid getting strong chemicals like paint removers and oven cleaners on the surface. If a spill of this nature does occur, you should promptly flush the surface with warm water and fully rinse off the spilled chemical.

You should not cut directly on top of your Corian® countertops. It is important to use a cutting board to prevent scratching and other damages. It should be noted that boiling water by itself will not harm your Corian® sink. Despite this, however, we still recommend that you run cold water from the faucet into the sink while pouring boiling water into it.

How to Remove Fine Scratches or a Blotchy Appearance

It is important to learn how to care for Corian® because without proper care you may begin to notice that the surface of your countertop will start to appear blotchy. This is typically caused by leaving hard water to dry up on top of the surface. This will, in turn,leave a film of minerals on your countertop.

In order to remove this type of film, follow the following instructions:

  1. Put some mild abrasive cleanser, like Soft Scrub®, onto a damp sponge or a damp cloth.
  2. Rub the affected area using small circular motions. Start front to the back and then move side to side. Make sure the circles overlap each other until the entire area has been completely cleaned.
  3. Thoroughly rinse the surface with clean warm water and WIPE IT COMPLETELY 100% DRY.
  4. Check the surface to see if if the blotchiness is gone. If it is not, repeat the above procedure and apply some more pressure on the sponge or the rag.
  5. Continue this process over all of the affected areas until the film is completely removed.

NOTE: While the application of this procedure may help to remove or even minimize the look of some very fine scratches, other deeper and more serious scratches may remain.

How to Remove Minor Cuts and Scratches

It is very important to learn how to care for Corian® when it is scratched because it can affect greatly its natural beauty and elegant appeal. Because the opulent beauty of Corian® counters extends all the way through the material, Corian® surfaces are in fact renewable. You are able to remove small, minor cuts and scratches yourself simply by following these easy instructions.

  1. First, you should wash the scratched area, as pertaining to the instructions found in this guide. You should also make sure to remove any film on the countertop surface as this film has the potential to clog the abrasive pads needed. With the surface still wet, start rubbing the affected area with the Peach colored side of the pad. It is important to use a light touch when scrubbing. Pressing too hard while scrubbing may actually leave deeper and more serious scratches. Rub over top of the scratch using a smooth straight line motion. Periodically switch the scrubbing direction ninety degrees to keep the pattern even. Rinse the cleaning pad periodically through out this process to ensure the removal of any built up residue. Make sure that the entire scratch is removed.
  2. Clean the top with warm water and then dry it thoroughly. Check to see if the newly sanded area blends cleanly with rest of the surface. Please note that after this process the sanded area might not perfectly match the remainder of the top. If you find it necessary, turn pad over and repeat the process. Rub over larger area in order to blend in sanding.
  3. If needed, continue with the sanding process utilizing the Aqua colored pad and if it is necessary, also the Gray colored pad. Do this until the desired gloss level is achieved. Finally, rinse out all of the pads that you used and allow them to dry before you put them away.
