Got a bunch of apple peels from making a few homemade apple pies? Use the peels to get your metal pots and pans sparkling clean. Caked-on grease, debris and other burnt-on messes can be released with the power of peels. Just toss a handful into the pan and add a few inches of tap water. Then simmer the mixture over low heat for about 30 minutes. The caked-on mess will begin to dissipate because the acid in apples peels will attack it, all without scrubbing or chemical cleaning products. And when you're done? You can compost the cooked peels.
