is corian porous
CorianÂ® is dishwasher safe. CorianÂ® is non-porous so food and most household stains wipe off with a sponge and soapy water. Stubborn stains like coffee, grape juice, ink, hair dye and food coloring rub off with an abrasive household cleanser and a Scotch-Brite pad. Even tougher stains disappear using fine grade (180-200 grit) sandpaper.
