Barkeep’s Friend is one of the best and most cost-effective products for cleaning many surfaces, especially stainless steel. You can use it to clean pans/pots (not for use on non-stick ones) and for your stainless steel sink. Some people also use it on their stainless steel appliances. The key is to do your work quickly and then clean it off quickly. Who says you can’t buy your friends? And this one is cheap and a real “keep”er, too!
