How to Get Rid of Black Stuff That Adheres to Toilet Tanks

Mold, lime and calcium deposits can form in any toilet tank that is left sitting for too long. If left untreated, this material will dirty the toilet water. This isn't a dangerous problem, as no one is going to be using toilet water, but it can lead to an unsightly color when you flush. Luckily, it's pretty simple to do a quick cleaning of the inside of a toilet tank, which should resolve the issue.

Things You'll Need

• Vinegar
• Scrub brush

Instructions

1. Pour vinegar into the toilet tank and let sit for a number of hours. This will loosen and dissolve the mold or calcium buildup and make it easier to scrub off. Flush the toilet a few times until the vinegar is cleared from the system.

2. Take a scrub brush and scrub the insides of the tank to remove the rest of the buildup. Be careful not to hit the mechanical parts inside the toilet tank, because you might bend or break them. When you've finished scrubbing, give the toilet a few more flushes to clear the tank of buildup.

3. Pour bleach into the tank, if you're still having problems with buildup after the vinegar and scrubbing. If this doesn't do the trick, give your local plumber a call and set up an appointment for them to look at the tank. It could be that you have a larger problem or need to have your toilet replaced.
