DIY Oven Cleaner: Mix up 5 T baking soda, 5 drops of Dawn, 4 T vinegar....mix into a paste & coat the paste everywhere with a sponge. Close the oven and let sit for about 15 minutes....come back and scrub. Can also put a few drops of dawn on a lemon & scrub for especially tough to clean spots.
My bathtub has never been whiter!! Works great on glass shower doors too- no more soap residue! Martha Stewart's Tub Scrub--works better than any other cleaning product to get off hard water and soap residue
