Easy fixes for a finicky toilet:

1. Remove stains with Coca-Cola.
Get rid of stubborn toilet bowl stains with a 12-ounce can of Coca-Cola. Pour the full can around the rim of your toilet so it coats the toilet bowl and let the soda sit for an hour. The acid in the Coca-Cola will break down the stains. After an hour, scrub the bowl with a toilet brush and flush.

2. Clear a clog with boiling water.
To fix a clogged toilet with little-to-no fanfare, fill up a medium saucepan with water and bring it to a boil on the stovetop. Carefully take the pot with the boiling water to the bathroom and pour the water directly into the toilet bowl. This will help dissolve…whatever’s clogging the pipes.
3. Remove mineral deposits with vinegar.Mineral deposits from hard water aren’t dangerous, but they sure are ugly! To get rid of these unsightly beasts, simply soak toilet paper in white vinegar and then set the wet paper directly on top of the hard water stain. Let the vinegar-soaked toilet paper sit over night. The next morning, just flush – your hard water stains will be gone.
4. Disinfect with hydrogen peroxide.To kick bacteria to the curb, all you need is a bottle of hydrogen peroxide. Disinfect your toilet by pouring ½ a cup of hydrogen peroxide into the toilet bowl. Let it sit for half an hour, and then flush. It’s that easy! Tip: You can use a combination of hydrogen peroxide and vinegar as a general disinfectant.
