Caring For Your Corian Countertops

DuPont_CorianCorian countertops are a solid surface material manufactured by DuPont. They are composed of acrylic polymer and alumina trihydrate (ATH), formed into sheets that are essentially seemless (source: Wikipedia). The countertops are even available with integrated sinks or backsplashes for even fewer seams in the kitchen.

Corian has been popular in kitchen and bathroom remodeling for several decades, probably because it is known for being extremely durable and stain resistant as it is a non-porous surface. It’s also said to resist bacteria, mildew and mold grow, with proper cleaning. This being said, it is important to take proper care of your countertops so that you can get the most out of them and to keep them looking their best.

Routine Cleaning
The DuPont website recommends basic care using a soft cloth or sponge along with warm, soapy water, an ammonia-based household cleaner, or a dedicated countertop cleaner and wiping the surface completely dry. They also recommend against using window cleaners and other products that can leave a build-up on the surface of your Corian. In cases where your countertop or sink needs to be disinfected, a 1:1 solution of water and bleach is recommended but must be rinsed off thoroughly with water and dried off.

DuPont stresses the importance of keeping Corian surfaces dry and wiping them immediately after cleaning or whenever spills occur. “Film will build up on countertops if water is left to dry on the surface. This film will dull the countertop surface, making the finish appear blotchy and uneven.

General Care
• Corian is heat resistant but you should still avoid placing hot pots and pans directly on the surface and your cookware should be allowed to cool off before you put it in a Corian sink to wash.
• To avoid scratches, do not cut directly on your solid surface countertop.
• Avoid getting harsh chemicals on your counter, including oven cleaners.

If your Corian countertop has been damaged, contact your professional installer about refinishing. Or, if you want to explore the possibilities of adding a solid surface countertop during your next home improvement, talk to your kitchen remodeler about the options that are available to you.
