Small circular stains are dotted on the inside bottom of my stainless steel saucepans after cooking vegetables; there also is a "cloud" on the bottom that is difficult to remove. Should I use a coarse scrubber or chemicals? The saucepans are new.
Try pouring a can of tomatoes into the pan and bring it to a boil. The acid in tomatoes ususally removes any stains from stainless steel. We have enough chemicals in our water treatement plants. . .
