How to Restore a High Gloss Corian Countertop

DuPont Corian surface material comes in three levels of gloss. All sinks and most counter tops have a matte finish, while some counters have a semi-gloss or even a high-gloss finish. Although Dupont designed Corian to be long-lasting and easy-care, soap residues can dull a high-gloss Corian finish over time. Hard water deposits can also create blotches and dullness. However, proper care can restore the shine to your Corian counters.
