I was given a used set of white Corelle dishes yesterday and I put them in the dishwasher and let them run through. So when I took them out, the first thing I did was inspect the reddish brown rusty stains that I had already noticed on them to see if the dishwasher had helped get them out. well, they didn't, the rusty stains remained. So I tried something. I put a little pile of baking soda right on the stain, wet a sponge and scubbed for a few seconds, and the rusty stains came right out.
Baking soda is cheap, and I think sometimes we overlook how good of a cleaner it really is. It saved my corelle from the garbage, but it can also be used to clean coffee pots, stainless steel (for getting the stuck on stuff off without scratching the metal, toilets, tubs, sinks, ovens, etc, etc. AND it does it all without harming the environment, an asthmatics breathing, an allergy sufferers allergies or your wallet.
Now polish away the cheap and friendly way!
