The dos and don’ts of caring for a Corian ® surface

Looked after properly, Corian ® surfaces will outlive the rest of a kitchen. A Corian ® surface that has been professionally fabricated and installed is completely sealed and non-porous, meaning it creates a durable barrier without having to be sealed.

As members of the DuPont Quality Network, every Corian ® work surface we install comes with a 10-year manufacturer-backed guarantee. And with a small amount of care and maintenance, your worktop will reach – if not exceed – this ripe old age.


Correctly treating a Corian ® surface comes down to proper care and avoiding a few key practices that can cause damage. We’ve summarised them in this handy list of dos and don’ts:

DO: Clean the surface regularly using a microfiber cloth and household kitchen cleaning spray.

DO: Wipe up spills when they occur, wherever possible.

DO: Apply Viakal gel to prevent discolouring caused by exposure to hard water.

DO: Apply household cleaner to a Corian ® sink overnight each week to prevent the build-up of grease.

DO: Use the correct treatment method for particular spills. These include:

  • Citrus and vegetable juice, tea, coffee, vinegar, dyes and perfume, pollen, polish and ink, blood, wine and mildew – use a damp microfiber cloth and a mild abrasive cleaning product (except on high gloss or dark surfaces).
  • Grease, fat and oil – use a small amount of dilute bleach and rub with a microfiber cloth. Make sure you rinse the area thoroughly with warm water afterwards to prevent staining.
  • Minerals, lime scale and hard water – apply lime scale remover or vinegar with a microfiber cloth and leave for a few minute before rinsing.
  • Nail varnish – use non-acetone nail varnish remover and rinse several times after.
  • Chemical spills – (e.g. paint stripper, metal cleaners, cleaners containing methylene chloride and acid) should be washed away immediately with soapy water

Corian repair in progress

DON’T: Cut or chop directly onto a Corian ® surface as small scores and abrasions can appear.

DON’T: Place hot objects directly onto the surface as this can result in small cracks. Always place pans and other hot implements on a heat protection pad or raised rack.

DON’T: Let your surface come into contact with water from an instant boiling tap. Direct exposure to boiling water can cause damage.

DON’T: Panic! Corian ® is a solid surface that’s renewable. Small surface scrapes and stains can simply be sanded away and more significant damage can be repaired. During a repair, a replacement piece of Corian ® is fitted and blended with the rest of the surface. (Take a look at the repair process in action in our blog, ‘Can you spot this Corian® repair?’)
