Have you ever noticed some toilets get more moldy than others? Even if you clean your toilet weekly, that black mold in your toilet tank keeps coming back!
What Causes Black Mold in Toilet Bowl?
Mold spores thrive in dark, damp places so it’s only natural to find mold in your toilet. However, some toilets can become moldier than others depending on your water or if you have calcium deposits built up in your toilet.
I’ve even heard that if your body has higher glucose levels from diabetes, your excrement can cause additional toilet mold!

While cleaning your toilet is a necessary part of life, there are several hacks that can help eliminate a few of the common causes of mold.
Before you do anything, clean your bowl like usual. I try to avoid chemicals as much as I can so I like to use natural cleaners, like Lemi Shine or this one.
Be sure to thoroughly flush the cleaner out of the toilet since you don’t want it to react with the next product.
Next, check to see if there is black mold in the toilet tank, the area behind the toilet bowl. If you notice mold in there you will need to treat it first since that is probably what is causing your chronic moldy toilet.
I’ve had a few friends tell me they’ve had success using Lime-A-Way Toilet Bowl Cleaner to your toilet tank in order to eliminate any mold buildup within the hidden recesses of your toilet. This way every time you flush a little Lime-A-Away is sent swirling through your toilet bowl to keep black mold from growing in the toilet. But keep in mind, it is a toxic chemical product and should be used as a last result to stop moldy toilets.
If you don’t see any mold buildup in the toilet tank, try using a Fluidmaster automatic toilet bowl cleaner. It’s made for the toilet tank (that way you avoid causing any damage to your toilet).
Natural Solutions for Toilet Mold
Looking for a more natural solution to moldy toilets? Try adding the Better Life toilet bowl cleaner to the toilet tank. It’s not as effective as the others mentioned above but it does slow the growth down.
Warning: Do NOT scrub your toilets with a metal or steel wool pad!
When we first moved into our house, I gave our toilets a good scrub but just couldn’t get a hard water line off of the toilet bowl so I used an SOS pad– BAD IDEA! It turned the inside of the toilet bowl grey!
Instead use this pumice stone to get any hard water stains off your toilets.

Cover the bowl with plastic wrap, pour muriatic acid down the stand pipe, and cover the tank with the same plastic after you pour it in, as the vapors are quite toxic. Open some windows. This will take care of the hardest of calcification. I live in an area with awful water and even with an acid wash I can only get two months or so out of my toilet before it’s got hard buildup and grime inside of it. DO NOT DO THIS IF YOU HAVE SEPTIC. Wait 15 minutes or so, flush, and scrub. Flush a few more times to dilute the acid. Works better than anything I’ve tried if you’re in a place with awful water like me (San Marcos, Texas). We have heavy metals, calcium, lead, magnesium, and really high amounts of chlorine (more than some public pools since they don’t use flouride here).
What’s the clever hack? Or am I just not clever enough to see the hack in this post?
Hey Jackie, The point is to put the solution into the backend of the toilet (vs just in the toilet bowl). That way it keeps it cleaner for longer.
