I've been using this product at least 20 years and it WORKS perfectly. YES, it will ruin rubber components in your tank IF you don't flush the toilet once a day---I learned this the hard way from personal experience. I will continue to use the product because it cleans effectively.

Clorox bleach tablets are a convenient and effective cleaning solution, particularly valued for their ease of storage and use. Each tablet dissolves quickly in water, making it simple to prepare a bleach solution for disinfecting surfaces, whitening laundry, or cleaning tough stains.

I was having to scrub my toilets every two weeks due to a brown ring that would form even in the unused bathroom. I dropped one of these in each toilet 6 weeks ago & the toilet rings stopped. I'm waiting to see how long it will actually last before I have to put another in. These things are great!

Clorox toilet bowl keeps your bowl fresh, however, it's not good for your toilet bowl Flush Valve. So, far I had to replace two of my Flush Valve because the bleach or additives in the ingredients is not good for equipment. It's best to clean under your toiler bowl, rather than thinking you're getting clean and fresh odor from inside. I did the repair myself, but if you don't catch in time, your toilet will be doing a Ghost Flush and you will be hit with a large water bill from the constant running of water into the bowl.

Really like that this product helps keep your toilet stain free and disinfected. I have little ones so the more germs I can kill the better. The after scent of bleach can be a bit much at times but I don't mind it cause I know that it means it works!

These are so simple to use. You lift off the lid of the toilet and place at the bottom of the tank. It takes less than a minute to set up and will help keep your toilet looking clean, its easy to keep a package under the sink or in a storage area. These are especially nice for powder rooms.

[This review was collected as part of a promotion.] I am a great fan of clorox products but this one is more disappointing. I hate cleaning the toilet. It says automatic toilet bowl cleaner for as long as the tablet lasts, you don't need to touch the inside of the bowl with a brush and it just stays clean all the time. I expected a lot.. It's been only two weeks and I am totally disappointed with this product. I followed the instructions and started using this but I didn't notice any difference in my toilet bowl. Planning to return and purchase a different one.

I used these in my new house and within 6 months all my toilets started having issues. The plumber came out and said that these type tablets eat away at the components in your tanks and cause so many problems. He said they don’t recommend using them at all and in fact will void your warranty.

I have been using Clorox bleach tablets on six toilets I have at my properties. The product kept clean the bowl, however they damaged the flush system in one of them (I have to replace the system) and in the others I am experiencing damages that have resulted on leaking water on the rest of my toilets. DO NOT USE THIS PRODUCT.

I was looking for a product to clean and disinfect my toilette bowl and none of the products I bought actually helped. Then i tried Clorox Automatic Toilet Bowl Cleaner and I was more then happy with it. My toilette is sparkling clean, fresh an bacteria free for over a month with only one tablet. Best product I have ever used.
