Gather Your Cleaning Supplies

Choose a cleaning product that is recommended by your sink’s manufacturer. DuPont, the maker of Corian solid surface, says to use an ammonia-based cleaner. Other manufacturers may recommend Soft Scrub, bleach, hydrogen peroxide, a Mr. Clean Magic Eraser, or baking soda and salt.

Also gather a scrub sponge or a scouring pad, such as a Scotch-Brite Greener Clean pad, as well as a stiff-bristle nylon scrub brush.

Spread the Cleaner

Wet the sink and spread your cleaner all over the sink basins. Leave the cleaner on the surface for the maximum recommended period. Cleaners with bleach often can be left on overnight (not more than 16 hours).

Scrub With a Sponge

Scrub the sink surfaces with the abrasive side of a scrub sponge or a scouring pad. Apply more cleaner and scrub some more.

Scrub With a Brush

Scrub in and around the sink strainer and other hard-to-reach areas with a scrub brush, reapplying the cleaner as needed.

Sand Out Minor Scratches

Inspect the sink for scratches that were not removed by the scrubbing. Sand remaining fine scratches with 400-grit sandpaper, either sanding by hand or with a small power sander.

Buff and Rinse the Sink

Buff the sanded areas with the scrub sponge or scouring pad to blend them with the surrounding surface. Rinse the sink thoroughly.
