They smell like chlorine, but you get use to the smell, now it doesn't bother me anymore. I gave some to my son and he likes the as well.It just makes it easier not to have to scrub the toilet every week.

These small bleach tablets for the toilet are great. They help clean my toilet and keeps it nice and clean and fresh smelling Thank you.

It does work well. It took awhile before it worked. We have hard water so it was very brown deep down.However, it has a very strong odor. It bothered my eyes. I could smell it even when out of the room. Now that it is spring I will try again when I can keep the window open.

I use these with another cleaning system I already had. I just needed these tablets. With this system no bleach touches the parts in the tank but goes directly into the bowl with each flush. It does smell of bleach when you first flush, but goes away pretty quick. Seems to be working!

I recently tried using chlorine tabs in my toilet tanks, expecting a quick and easy solution to brighten stains, but I ended up with significant issues. Upon opening the package, I noticed that these tabs emitted strong chlorine vapors, very similar to the fumes from pool chlorine tablets. While they did help to clean and brighten the stains inside the toilet bowls, I quickly realized that the product’s effects went beyond what I had anticipated.The real problem began after using these tabs for a few weeks. I started to notice a greenish layer forming on the metal parts inside the toilet water tanks. This corrosion spread to components like levers, handles, and other metal fixtures. It looked similar to the green patina that develops on copper over time. At this point, I recognized the issue as chlorine corrosion. As a pool owner, I’ve experienced firsthand how chlorine can corrode metal, especially when stored in a confined space. This is why I always keep my pool tabs in an open area, so they don’t corrode nearby metal objects.Unfortunately, the chlorine in these toilet tabs had the same effect. Within a month of using them, I was forced to clean off the corrosion and replace several parts in my toilet tanks. The damage wasn’t just cosmetic—it led to extra costs and time spent repairing the toilets.I would caution anyone considering using these chlorine tabs in their toilet tanks. While they may help with cleaning, they pose a significant risk to the longevity of your toilet’s internal components. The corrosive effects of chlorine on metal are real, and in a confined space like a toilet tank, the damage can happen faster than you might expect. Buyer beware—if you value your toilet’s parts, I would strongly advise against using these products.

I love these but the bleach smell is so strong that it’s horrible.

This product cleans perfectly my toilet.

Use these all the time, but the effective time is short
