If you're short on cleaning supplies, or don't want to spend the money on them, look no further than your refrigerator to get your toilet sparkling clean. Just pour a can of Coke over the yucky stains inside your toilet and let it sit for at least an hour. The acids in the soda will break down the grime. If your toilet is super grimey, use a couple of cans of Coke, and let it sit for several hours or overnight. Then, just use a toilet brush to loosen the filth from the bowl and flush! Your toilet will look like new. Fini! Who knew?
