I use this product in both bathrooms in my house (soon to be three) and I have never had an issue. I see people complaining about this product causing damage to rubber parts after two weeks or miraculously removing blue rings in toilets from previous owners then eating the rubber. Having problems after two weeks is a coincidence. Blaming this product is scapegoating for either using inferior replacement parts or for a part that failed because its time had come. And if you need to remove blue ring stains from a toilet bowl what quality of parts were used by all previous owners? The manufacturers of replacement parts for toilets know what’s being used and use chlorine resistant rubber or equivalent compounds to eliminate the hazard. The use of OEM parts is so important. Stop trying to save 30c and purchase quality brand name manufacturer replacement parts. Knockoffs are called knockoffs for a reason. This blame game is unnecessary and you can return to your regularly scheduled program and flush with confidence! Clorox is on the job after you’ve done yours.

I have been using this superior product for years. This is one of those items you are willing to pay a little more for to get the most desirable results from. Having a clean commode is a must. I trust the cleanliness of mine to Clorox® in between cleanings. Each flush is a blast of cleanliness and freshness. My family and company always comment on the fresh smell and appearance of my restroom. I clean the entire room with the fine family of Clorox® products as they compliment each other in a way no other cleaners can!

[This review was collected as part of a promotion.] I had constant iron issues with all four of the toilets in the house, and was seriously considering purchasing an expensive iron filter. The toilet rims and bowls required cleaning every several days due to the iron levels. I happened to see these tablets and thought I would give them a try, and so happy that I did. It is night and day!! There are no further issues with the iron flakes in the rim and the bowls stay nice and clean. THANK YOU -- THANK YOU!!

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.

[This review was collected as part of a promotion.] I am an avid Clorox product user and am typically happy with the products. However, I purchased a faulty tablet as it did not dissolve and it got stuck underneath the boot of the tank causing the toilet not to flush properly until the plumber removed the toilet to find the undissolved tablet. I will not be purchasing this product anymore. I'm pretty disappointed.

We have been using this product for a couple of years. Today I noticed an issue with one of our toilets. I removed the cover on the tank. The tank was full of a yellow glue like substance that covered the tank, float, and flapper valve. The float was stuck causing the water to run continuously. The other toilet had the same issue just not as bad. After extensive time consuming cleanup, I was able to get the toilets working again. I don't recommend buying this product!

Bleach corrodes the components in your tank. Do some research online. Yes the cleaning power of bleach is great, but at what cost? If you don’t mind a leaking toilet and replacing it ever few years, this is for you. Otherwise just clean your toilet regularly.

[This review was collected as part of a promotion.] I love this product, I have been using them for years. It does mess with rubber in tank only after a very long time but that is cheap and easy to replace considering how clean the toilet bowl and nice smelling it is at all times. I love the 6 pack, I buy it in bulk that way. Phyllis in New Orleans

I have been using the for over a year. I had been taking a record of how long they last. well it was only 18 -to 20 days. not good. says it works up to 3 mo., well that is true. last time for me. I want all my money back. for over a year. we have bought at least 12 or more over the years time. sad...…...

I recently decided to try the Automatic Toilet Bowl Cleaner since I was unable to keep my toilet from staining and not from my own doing. I think it has something to do w the water. So far so good. I will continue to purchase this. Makes my weekly cleaning so much faster.
