When we remodeled our kitchen about 18 months ago, I had a couple people warn me about corian sinks - that they stain, scratch, and require extra maintenance.
I do agree that they are higher maintenance, and I might go with stainless steel next time. But for this time, the corian sink was free with the countertop purchase - and both David's and my parents still have corian/ceramic sinks that look great in their kitchens! And also I like the gleaming white. Some people like white countertops, I have enjoyed a gleaming white sink.
So while the white sink does show coffee stains and marks if we wash our cast iron pots, I just attack it with some soft scrub with bleach every couple weeks! (It has to be a soft scrub that says "with bleach" in it. I accidentally bought one without bleach the other day and I couldn't believe its non-effect.)
This is the before. Not particularly terrible, but not shiny either. I have found the best combo to be my soft scrub with bleach + my earth friendly scrubber (I use the rough side on the sink, and if I need to scrub anything off the countertops I use the smoother side).
Let's zoom in so we can see those yucky spots.
Eesh. I swear I used the same white balance on all these photos!
So. Spread some soft scrub around and scrub with the rough side of sponge. Look at all the discolouration coming off!
Five minutes later: Done. Rinse out the sponge and save it for another day.
So simple. A year and a half into our kitchen and our sink looks brand new!
Best use for soft scrub (with bleach) ever. Also I like knowing the sink gets bleached out every couple weeks. Even though we almost never have meat in the kitchen, I still like bleaching the sink...maybe because of that Mythbusters' episode where they found more germs in the kitchen sink than the toilet?? Although I think the germs they found in the toilet were a worse kind than in the sink...
Bonuses: Soft scrub also does a great job cleaning settled grease and grime off our stove, and I use it occasionally to restore my teapot to its shiny self!
