Is It Safe to Use Blue Tablets in My Toilet Tank?

We’ve all seen toilets with a vibrant pool of blue water — courtesy of tank-cleaning tablets. While they may seem like the perfect way to clean and sanitize your toilet, the reality is that they are quite harmful to it.

Those blue toilet tablets can cause corrosion to parts inside the tank and contain harmful chemicals that may be released into your home and the environment.

Here’s why we recommend skipping the blue tablet and what you can do instead.

Reason #1: Blue Toilet Tablets Can Wear Down the Flush Valve

One of the most important pieces of your toilet is the flush valve. Living up to its name, this part helps move water into your toilet. However, if you use blue cleaning tablets, the harsh chemicals they contain can corrode your toilet’s flush valve (as well as other internal parts) or get stuck inside it.

This will make flushing your toilet impossible and, if not repaired promptly, may cause a potential plumbing disaster.

Reason #2: Blue Toilet Tablets Emit Chemicals

When it’s time to clean your bathroom, you’d typically open the windows (if there are any) or turn on the exhaust fan to help get rid of any potentially harmful chemicals that may be emitted from your cleaning products. When you use a toilet tank tablet, the blue disc can emit chemicals non-stop, harming you and the environment.

Additionally, if you have a dog or cat that likes to drink from the toilet (despite your telling them not to), consuming this chemically treated water in excess may harm them.

Alternatives to Toilet Bowl Cleaner Tablets

If you’re still torn on whether or not to use toilet tablets, then the best solution is to avoid them. Sure, they boast that they can keep your toilet fresh after each flush, but the downsides aren’t worth it.

Of course, the best way to keep your toilet clean is to consider using green cleaning agents (or those with little-to-no chemicals in their composition). These agents will maintain a clean toilet and save your plumbing over time.
