Are Corian sinks supposed to stain?!
I agree with you — it’s a sink, for goodness’ sake! It shouldn’t stain like that. I have stainless — I’ve always had stainless — and I have NEVER had a stain. I wash out paint brushes and craft stuff, make plenty of tomato sauce, and never a problem. The only back thing about stainless, IMO, is scratching. But you know, it’s a sink and I just don’t care all that much.
