How to Clean Corian Worktops

Corian is built to last. Follow our simple how to clean Corian worktops guidelines to help maintain the beauty of your Corian surfaces. Although Corian is completely non-porous, it is still advised that any spills are wiped-up immediately. A damp microfiber cloth is fit for this purpose; use a standard kitchen spray to remove any stains that occur.

Avoid using window cleaners on your Corian worktops, as they can leave a waxy residue that will dull the surface. For most substances, warm soapy water, an ammonia-based household cleaner, or a dedicated worktop cleaner will be enough for cleaning your Corian countertops. Always clean with a lint-free cloth, using a circular motion.

If water is left to dry on the surface, a film will build up and dull the surface. Over time, the finish will appear blemished and patchy. To prevent water marks, water should be wiped up immediately from the surface. Use a lint-free cloth in a circular motion to ensure the surface is polished dry.

Over time, your countertop will gain a sheen to its surface. Some Corian colours may require more frequent care and maintenance. Darker colours tend to require this frequency over lighter colours. Please note that dark colours can show light scratches more easily but rest assured —Corian countertops can be easily restored.

Corian® Sinks

Dealing with potent stains

In order to clean Corian worktops from household spills with more potent items, such as vinegar, lemon juice, coffee, tea, dyes, ketchup, red wine, potent spices etc. specific action should be taken. For information, refer to the table in our use and care guidelines.

Hard Water

Hard water can cause a limescale and staining on your Corian surfaces that will worsen over time. If you are experiencing the effects of living in a hard water area, to clean Corian worktops we recommend “Viakal” gel. Apply and leave “Viakal” gel to the affected area and leave for 2-4 minutes. After time has lapsed, remove the gel with a damp microfiber cloth. Using a clean microfiber cloth, rinse the area thoroughly with water. If any residues remain, use a a mild abrasive cleaning product and cloth to work on the area.

Preventing Damage

In most cases, if a Corian surface is damaged, it can be easily repaired. However, please make sure to follow these guidelines to help you prevent any permanent damage to your Corian countertop.



Corian is heat resistant but is not heat proof. As with all countertop materials, it is vital to avoid direct heat exposure to your surface. All heat as stated below, can and will cause damage to your Corian surface:

  • DO NOT place hot items (such as pans, kettles, oven pots etc.) directly on the countertop surface.
  • DO use the correct size pan for your hob and place centrally. An overhanging pan will scorch the surrounding surface.
  • DO use heat trivets when placing hot matters on any surface.
  • DO use heat protective items under portable heat-generating appliances, such as a toaster oven.


Boiling Water

  • DO Allow pots and pans to cool before placing into a Corian sink.
  • It is a recommended practice to run cold water from the faucet while pouring boiling water into the sink.
  • In every-day use, Corian will develop slight abrasion marks however, to avoid heavy damage, never cut directly onto a Corian surface. Always use a chopping board when preparing food
  • We do not recommend the use of instant boiling water taps with Corian sinks. boiling water from this type of tap may cause surface damage in and around the Corian sink. If a boiling water tap is installed with Corian, a container should be used within the sink to collect boiling water.



Please note: Dark and heavily pigmented colours will show scratches, dust and ordinary wear and tear more readily than lighter, textured colours.


Chemical Spillage

n order to clean Corian worktops if there is a spillage of any strong chemicals on your Corian surface, immediately wash the area with plenty of soapy water to avoid damage the countertop. These harsh chemicals include: paint stripper, spirits, metal cleaners, oven cleaners, cleaners containing methylene chloride, acid drain cleaners, acetone based nail varnish removers;but there are many others.

Varnish and paint spills, a non-acetone-based remover can be used. that then is flushed away with water. Unnoticed and lengthy exposure to chemicals will damage the surface.

Please note: Any damage to Corian surfaces caused by not adhering to the above guidelines would not be covered by the DuPont 10 Year Warranty.
