Fluidmaster 8302P8 Flush 'n Sparkle Automatic Toilet Bowl Cleaning System Bleach Replacement Cartridge Refills, 2-Pack

With experience over the years trying many different products, I've found that the only toilet cleaning solutions that are effective are those where the cleaning solution actually passes through the flush system (i.e., through the holes around the rim). The types that just clip onto the edge of the bowl are cute, but ineffective at actually keeping the toilet clean.There are many products sold that go in the tank which are effective at cleaning, however, they are harmful to the internal components and cause premature failure that can lead to leaks, and possibly property damage.The Fluidmaster system cleans effectively, without causing any damage to the toilet components. Its design is simple, yet genius. It consists of a small unit that connects onto the refill line, between the fill value and refill tube. The unit accepts a replaceable bleach cartridge and is completely sealed. When the toilet is flushed, water passes through the cleaning system, directly into the refill tube. This water passes through the flush holes and into the bowl, allowing the cleaning solution to be evenly distributed without any of the solution entering the tank.With this system clean water from the tank is used to flush, followed by the water with cleaning solution as the toilet refills.They claim that the bleach cartridges last approximately 3 months and I imagine that depends upon the amount of use. Unlike the bleach tablets you put directly in the tank which will continue to dissolve even without use (and thus the bleach content gets stronger and stronger), the Fluidmaster cartridges only get used when the toilet is flushed.This is by far the best cleaning system I've seen. It's simple, affordable, and effective. If you hate constantly scrubbing toilets, you may want to get this. We tried it in one of our toilets and it worked so well we bought three more. Oh, and if you're worried about remembering to change the cartridges, Fluidmaster has a website where you can sign up for reminders (and I'm sure they'll be more than happy to sell you the refills as well.) You can also get these on Amazon Subscribe and Save at a good price. That's what I did, so when they show up, I know it's time to change them.Also, as a side note, I did try buying chlorine tablets and using them instead of buying the replacement cartridges, as many others have done. While this option may be slightly less expensive, I've found that not to be a good option for several reasons. First, the chlorine smell is unbearable, even if I used only 1 tablet instead of two. Using bromine tablets would probably be better for that issue. Secondly, the chlorine tablets continue dissolving inside the cleaning system, even when the toilet is not used much. I had put 1 tablet in one of the toilets that we do not use much and after a week or so I flushed it and the smell was at toxic levels. I removed the cartridge to inspect and it had mostly dissolved and the fumes nearly killed me. The Fluidmaster refills do not seem to have this problem, as I've inspected all 4 of our toilets regularly while using them over the past year and find that those that are not used much stay intact, while those used more often dissolve faster. This is better as they remain effective for much longer in most of our toilets and I only have to replace the ones that are used more every 2-3 months. I'm not sure what's different about the tablets in the refill cartridges, but I've found it better to just buy them less often than trying to keep up with the chlorine tablets.I can say that our toilets do stay much cleaner using this system, so it has been worth the investment.

Fluid master is the brand we repeatedly go to for quality tools in plumbing needs. We wanted to avoid the repeated changing out of toilet flapper valves and tank hardware caused by bleach tablets in the tank breaking down those components. This system works perfectly! The cartridges last 3-4 months each, the toilet bowl stays crystal clear clean w/o all the scrubbing you normally have to do. So easy to install, fits in any toilet. Pleasant clean smell with every flush. Protects from mold, toilet rings and I’ve never seen rust. Would recommend for everyone. Cartridge replace is easy: without flushing, simply unscrew out the old cartridge and drop in the new one screwing it down tight. They even supply you with a small ziplock bag for old cartridge disposal. We use in all our bathrooms now. 🙂

It's easy to install and does a good job keeping the pink stains from forming, however, it gives off an odder that I find objectionable. I bought the clear bleach version, perhaps the blue version doesn't have the same odder.

This is a great product for getting bleach into your bowl without ruining the parts inside your tank. It’s easy to install. The refill cartridges are expensive to me and waste plastic but chlorine pool tablets in the 1” diameter size fit inside. It’s a bit of work to get the bottom off to refill but the pool tabs last a long time and save plastic and money.

As a licensed plumber I had been looking for something for a long time to recommend to my customers to keep the ring in the bowl, so I tried the product at our house first myself to test it out before I decided to recommend it to my customers,.and I have to say it works really great and it does keep the ring out of the bowl. Now Fluidmaster recommends replacing the cartridge every 3 months, however it varies from household to to household, it all depends on how often the toilet is flushed. I wish they would have recommended the amount of flushes for each cartridge rather than months. if you're Flushing a lot more often than usual I would recommend replacing the cartridge every 1 1/2 to 2 months as it can run out before the third month. I replace ours every two months in my household. With that said you will just have to monitor it check the cartridge from time to time see how fast it's dissolving to determine when it needs to be change it out, but the product works really great and I do recommend it to my customers. (A little disclaimer) here, we personally have a water softener with a water conditioning system at our home. If you have really hard water and you don't have a softener or conditioning system at your home the results May very. I don't have enough data on that yet to make that determination vet. Another common question that a lot of my customers have about the product is, does the chlorine going to affect the parts in the toilet tank itself? and the question is NO the way it's set up in the toilet tank it diverts the chlorinated water into the filush valve tube and down into the bowl on each flush so the chlorinated water only goes into the bowl not the toilet tank itself. And this product is very easy to install. Another question I get will this work on any toilet and from what I can see it works on just about any toilet I haven't come across one yet that it didn't work on.
