Bartender’s Friend

I use all nontoxic cleaning products for my normal routines. But sometimes there are just hard problems that only a more commercial grade cleaner can get. Bartender’s Friend, a cleanser sold in many supermarkets and hardware stores, is not a green product (though it’s lower in toxicity than many others) but is unrivaled in getting out rust and black marks from bathroom fixtures and kitchen counters. It’s a very good resource of last resort for some of those hard-to-get issues.
