Day-to-Day Cleaning
There are three types of Corian surfaces: matte/satin, semigloss and high-gloss. All Corian sinks have the matte/satin finish. Day-to-day cleaning of all three surface types can be done with soap and water or an ammonia-based cleaner. For tougher stains, each finish requires a slightly different type of care.
Stain Removal for Each Finish
For the matte/satin finish: use an abrasive cleaner and a green Scotch-Brite pad.
For the semigloss finish: use Soft Scrub or diluted bleach and a white Scotch-Brite pad.
For the high-gloss finish: use Soft Scrub or diluted bleach and a sponge.
Special Considerations
Removing hard water stains: To remove hard water stains, wipe with a clean, damp cloth and towel dry until the marks disappear.
Removing nail polish: To remove nail polish from Corian, use only non-acetone-based nail polish remover. Wash the area with soap and water to remove any residue.
Removing oil/grease from sinks: Partially fill the sink with hot (not boiling) water. Add 2 tsp. bleach. Be sure the room is well ventilated. Let sit for a few hours, then drain the sink. Rinse well.
Tea/coffee stains: To remove tea and coffee stains from Corian, make a thin paste of baking soda and water, then gently rub with a sponge onto the stain. Rinse well with clear water. This mild alkali solution should easily lift the oily residue from the surface.
