We bought a new stainless steel sink, and to our dismay, it scratches and rusts at the smallest provocation. Set a glass cup in it? Scratch (I didn't even know that was possible). Leave a plastic tupperware container in the sink for two days? Rust ring. It's ridiculous.

The rust can be scrubbed away with a sponge, but the scratches really bother me. Is there something we can use to buff out the scratches? Or at least coat the sink with something so it doesn't scratch more?
