4. Cleans Toilet
After you try this you’ll never use that blue toilet bowl cleaner again. All you need to do is fill your toilet bowl with a 2-liter of coke and let it sit for a few hours. Once you flush, not only will the stains be removed, but the bowl will blind you with how gleaming white it is. That’s a good $1.99 well spent versus $5.99 for a bottle of toilet bowl cleaner that’s not guaranteed to work.
