clean you oven with 3-4 drops of Dawn, 4 T. of Baking Soda, 5 T. of Vinegar, Juice of a lemon or lime. (Pour in vinegar SLOWLY!) Wipe paste onto the surfaces in the oven. Let it set for a couple of hours. Wipe out with a sponge or warm cloth.
"That’s right, a lemon! I just cut it in half and use the actual lemon to scrub the hard water stains on any fixture. I’ve even used it to remove rust stains from a bobby pin I left sitting in the shower. Like I said, just rub the lemon on the fixture and rinse. The spots will magically disappear before your eyes and you’ll be left with this!"
