How to Bring Shine Back to a Corian Countertop After Sanding

Jennifer Eblin

Corian countertops come in a variety of patterns and colors, including designs that resemble other materials, such as marble or stone. If you clean and maintain the counters properly, they may last for years. Sanding the counters removes the original shine from the Corian surface and leaves behind a dull and faded appearance. Cleaning your countertop the right way will help restore the shine that you want.

Step 1

Mix a few drops of mild dish washing detergent with warm water in a plastic bucket. Clean the Corian counters with the solution, wiping it on with a sponge. Rinse the countertop with fresh water and wipe it dry.

Step 2

Wipe down the surface of the counters with an ammonia-based cleaner designed for cleaning bathrooms. Go over the surface carefully, removing any dust or buildup left behind by the sanding. Dry off the counters with a soft cloth.

Step 3

Apply a small amount of Soft Scrub to a soft cloth. DuPont, the manufacturer of Corian countertops, recommends this product for scratches and scuffs. Move across the scratches, rubbing the cleanser on the counters in a circular motion, side-to-side then top-to-bottom. Rub a dry cloth across the counter to remove any excess product.

Step 4

Pour nonabrasive polish onto a soft cloth and rub it across the counters in a circular motion. Work from one corner of the counter to the opposite corner. Move down and keep rubbing, overlapping in circles as you polish the countertop.

Step 5

Buff the counters gently with a soft cloth. After the counters absorb some of the polish, gently rub a dry cloth across the Corian. The cloth absorbs any excess polish and gently buffs the countertop, bringing back its shine.
