Good tip! If I recall one benefit of Corian is that it's non porous. I think Dupont suggests some pretty (comparatively) strong cleaners for regular maintenance.

I just bought some Bar Keepers Friend and I'm amazed at how it cleaned my porcelain sink. I have a white porcelain sink that I have "pads" on the bottom and for some reason they turn the sink yellow plus you know how any metal that hits the sides makes black scratch marks...well I just used BKF and the sink is as white as new. NOTHING, I MEAN NOTHING else I tried made a dent in the stains. Warning...whatever you do, don't have porcelain sinks put in your kitchen. I absolutely hate them! They stain like crazy, they break dishes(reason for pads in the bottom).
