Corian countertops are popular among home and business owners due to their durability and affordability. Countertops made from Corian are more resistant to scratching and staining compared to countertops made from natural materials. Properly cleaning a Corian countertop, however, is necessary to preserve the quality and life of the counter. Using the proper cleaning materials will help avoid film buildup and will keep the Corian in good condition.
Use soapy water. Pour a few drops of dish soap into a tub of warm water. Use a nonabrasive cloth towel or sponge to wipe the countertop with the soapy water. Rinse thoroughly with warm water. Use a dry cloth towel to wipe up any excess moisture. The Corian countertop must be wiped completely dry to avoid forming a film.
Remove tough stains with an ammonia-based cleaner. Ammonia cleaners will also prevent streaks and residue buildup. Spray an ammonia-based cleaner on the countertop. Use a dry cloth towel to work the cleaner into the Corian countertop. Rinse the countertop thoroughly with warm water. Use a dry cloth towel to soak up any excess moisture until the counter is completely dry. Do not use window cleaner to clean the countertop. Window cleaner will cause the countertop's finish to break down.
Use a bleach solution to disinfect. Combine one part water to one part bleach in a spray bottle. Spray the Corian countertop with the bleach solution. Use a dry cloth towel to rub the bleach solution into the countertop. Rinse thoroughly with warm water. Use a dry cloth towel to wipe away any remaining moisture.
Remove hard water stains with a limescale remover, such as CLR or Lime-A-Way, to remove stains created by calcium and hard water buildup. Apply the cleaner according to the manufacturer's instructions. Rinse with warm water. Use a dry cloth towel to wipe away any excess moisture until the countertop is completely dry.
Remove minor scratches and film buildup. Apply a mildly abrasive bleach-based cleaner, such as Soft Scrub, to a damp nonabrasive sponge. Use small back and forth motions to gently rub the Soft Scrub into the countertop. Repeat the process making the motions in the opposite direction. Rinse thoroughly with warm water until the cleaner residue is washed away. Use a dry cloth towel to wipe away any excess moisture until the Corian countertop is completely dry.
