HOPE'S Perfect Countertop Cleaner and Polish 22-Ounce, Streak-Free Multi-Surface Cleaning Spray, Safe on Stone, Laminate, CORIAN, Granite, Quartz, Marble, Pack of 6

Very nice for Corian - in fact they recommend this... But you do have to use it like a polish and buff it in rather than just a quick spray and swipe... I don't mind that (buffing and polishing), but think my cleaning people would rather use something that's more of a quick spray and swipe. ;-)

This polish really works. Be prepared to use some elbow grease to buff it into a shine.
