We installed a nice Kohler porcelainized cast iron sink many years ago in our previous home. It was a very nice sink. We also bought the rubber footed stainless grate that went in the bottom of the sink to protect it. We left the grate in the sink all of the time. We were on city water, which I think was not very hard, but a little hard.

WHere the feet of the grate were got "stained". Thinking about it now, I think that's because having them in the sink 24x7x365 allowed some hard water build up and the build up stained. Back when we had it, I thought it had been scratched by having grit get between the rubber feet and porcelain, but now I'm thinking that's not the case.

I know that I've seen my grandmother keep a plastic tub in the sink that she used when washing dishes to protect it.

What methods do you guys use to protect a porcelain sink and keep it looking nice?
