Using bleach tablets to clean the toilet is one way to save time, not to mention avoiding the gloves, brush, and cleaner. But it turns out that bleach tablets can slowly cause damage to the rubber seals inside your toilet, causing unexpected leaks and repair bills.

Caustic Cleaners, Leaking Toilets

Bleach and other cleaning tablets are caustic, meaning they break down weaker materials, such as rubber, over time. Those bolts that hold the tank to the toilet bowl aren't very robust, nor are the the rubber gaskets. You may find yourself with rusted bolts and a leaking toilet in as little as six months. Then you'll have to replace all the inside components of the toilet. But hey! It'll be clean.

Cheap Tablets, Blocked Pipes

Another potential drawback to the bleach tablets comes from cheaper ones that can break apart over time. If a piece of the tablet breaks off, it can get sucked into the tiny passages inside the toilet and block the water flow. While it will eventually dissolve, you might notice that your toilet doesn't flush correctly for months. Water might be slow to fill the drain or can even slow to a trickle.

So what should you use to clean your toilet?

If you decide to use a cleaning tablet in your toilet, it should always be placed into the toilet bowl, not in the tank. While it might be a little unsightly, there aren't any parts in the bowl that can be damaged or blocked.

Don't want to use an in-bowl tablet? A good old fashioned toilet brush and a spray cleaner every week is a great alternative!
