Preparing to clean the toilet tank

House cleaning, especially toilet cleaning, is nobody's idea of a good time. While the toilet bowl might get weekly love, do you think about cleaning the toilet tank? The toilet tank holds that water that flushes everything down and doesn't get the love it deserves. Learn how to clean your toilet tank with vinegar to reduce algae, rust and mold.

How to Clean the Toilet Tank

Before you can clean the toilet tank, you need to get the water out. Pouring vinegar in the tank won't get rid of that grime, rust and mold without draining the water first. You'll want to shut off the water valve somewhere around the base of the tank. You'll see the water line under the tank, just follow it until you reach the valve. Then, you'll give it a few good flushes until the tank is completely empty. With an empty tank, it's time to grab your tools.
