Sprinkle baking soda onto a damp nylon mesh sponge and scrub the stained area. Let the baking soda sit on the stains for one minute. Rinse with water and dry with paper towels.
Clean remaining spaghetti sauce stains with a paper towel soaked in bleach. Lay the towel over the stain and press it so the bleach comes in contact with the sink. Leave the paper towel in place for two to three minutes. Remove and discard the towel in the trash. Rinse the Corian sink with water and dry it with another paper towel.
