Self Cleaning Toilet System Replacement Cartridge, 1.65 oz, Lasts Up to 3-5 Months Continuous Toilet Bowl Cleaning - 6 Pack

I have this cleaning system on four toilets in my house. Really keeps the bowl clean, reducing amount of times I have to do that chore. I like the way treated water bypasses tank as this also keeps chemicals from eroding the flapper valves.. Nice product and have been using for probably at least seven years with no ill effects... Recommended.

works good.

I have seven trolleys in my house and have been using this for years and it has been amazing!

This has worked better than any other product I have purchased for cleaning toilet bowls. You will occasionally need to scrub since no product is perfect, but it goes longer between cleanings than alternatives. Easy installation and then you can forget about it for weeks as it does its thing before you need to place a refill in when the crystals are used up. Very light bleach smell but most of the time I do not notice at all. I've been using this for years and have been happy with the performance.

This product works as well as advertised and in fact for me it seems to last much longer than advertised. Very easy to use (set it and forget it) and it just works. One nit-pick to me is that the odor may be off-putting to some (it does have a mild chemical smell that lingers a minute or two after flushing), but to me its not bad and worth the minor inconvenience considering the job it is doing.

I've been using NeverScrub! Self-Cleaning Toilet System for several years now, and I'd highly recommend it. Unlike the chlorine pucks that you put into the toilet tank which destroy all of the gaskets in the toilet tank, the chlorine from the NeverScrub NEVER goes into the tank. Instead, the water tube that sends water into the toilet bowl when you flush, runs though the NeverScrub chlorine and delivers it into the toilet bowl while the toilet tank fills with water! Truly a GENIOUS invention! I highly recommend this!!

I used NeverScrub about 10 years ago then we moved and the toilets were not set up to be able to use the NeverScrub. Well we changed the working in the tank of the toilet and am now able to use them again. I order the full set with the holder and installed them on the toilets and then one day I saw that the toilet was not clean and thought it was that the Neverscrub no longer worked like when I bought it 10 years ago, and I was so disappointed. Then I looked and realize it had been 6 months since I installed the Neverscrub. So I cleaned the toilets and refilled the neverscrub and I am now a very happy housewife. I will continue to use Neverscrub as long as I have toilets.

I have always been able to get this product in Publix, but for some reason they stopped carrying it. I was thrilled to find it on Amazon, and bought 12 refills right away. I don't know if I can live without this product. It does not sit in the toilet tank like other products, so it doesn't destroy the seals in the toilet. It keeps the toilets stain free, even ones that are not used very frequently, like the ones in our vacation home in Florida. If you live in Florida, you know how the toilets can get, especially if you are gone for a few weeks to months. The person that invented this product is a genius!!! You have got to try this product and keep them in business!
