Kitchen sink?

Real Corian shouldn’t have stained. So what is the nature of the stains? What color is it?

The scratches can be machined our by a licensed/certified fabricator.

call Corian and ask them for a licensed/certified fabricator.

if you want to clean the stains yourself, then use a nylon scrub pad with Ajax or Comet.

For lights cratches, a mild abrasive cleaner like Comet and a light scour pad.

I would contact the manufacturer for the best method for repairing and cleaning the countertop and sink.

I have an old acrylic sink (never again) and it gets some nasty stains. The easiest and best way I have found to clean it is with bleach and baking sods.

Make a paste (the thickness is up to you but it needs to be thick enough that it will cling to the sink).

I put the paste on the stains in the sink before I go to bed so it has all night to work.

This get out more stains then any other process I have tried and this is very cheap to do.

Hello MAS, hope this helps you out,

I used to have a Corian sink, and I used 2400 wet grit sand paper on it to get the stain out. Then would bleach the area. I got new granite and the sink was replaced. I made the mistake of getting a black granite sink. I know how to clean it, but what a job.

Try baking soda. Although it usually works it is temporary and has to be re applied regularly.

We've used Bon Ami, it's very gentle.
