Why don't you call Corian and ask for cleaning instructions. If I remember correctly, stains are sanded off with a super super fine sanding paper. No bleach or any other harsh chemicals.

I went to DuPont Corian and got their advise and link for a product that they said would work. Their link was to the wrong site. When I googled the name of the product they advised I found that Amazon.com sold it. When I went there, I read the consumer reviews. Many said the product didn't work for their stains and was useless. A few said they tried Bar Keepers Friend and it worked wonderfully. So that is what I am going to do. Thanks anyway.

There was a discussion on Corian just today on the Kitchens site.

Note this comment " I have been refinishing Corian for over 20 years and have not met a "stain" that I couldn't remove with a green Scotch Brite pad" (Trebruchet)

I had it an a bathroom 25 yrs, I didn't have so much of a problem with stains as little white marks, dropped items....

The discussion is kitchen counters but cleaning wouldn't be remarkably different...
