8102P8 Flush 'n Sparkle Automatic Toilet Bowl Cleaning System Refills, Blue 2-Pack, Upgraded Version

Great toilet bowl cleaner.

Have been using for years, does work.

This product can last up to a few months depending on how often the toilet is flushed. Not sure of the consistency of the product because sometimes it looks like it is purple. This product won't completely clean your toilet, but it will definitely help you scrub the toilet less. I prefer the blue look over the clear look, since I will know when it stops working. And this product won't damage the toilet parts since the cleaning product is funneled into the water supply line as opposed to sitting in the tank.

I only ordered these because the title strongly suggests that these are a new and upgraded version. No, they are not. They still only offer an extremely limited life and don't work well either. The blue contents become gooey and will clog the tubing. Wear gloves when you go to throw these out! I was going to try to recycle these and put come cut up bromine tablets in mine (as I usually do), but these are just too damn messy. If you get a sharp and extremely thin knife, you can use the blade to pry off the bottom cap and refill with your own tablets. I don't know how many times you can reuse/refill these until the washer needs to be replaced, but it can be done and may be worth some savings for you.

I have been using the Fluidmaster Flush 'n Sparkle Cleaning system for about four years to help control black mold and mildew that tends to grow under the rim and in the bowl. The chlorine bleach cartridges have definitely helped control the excessive mold and mildew buildup but I still needed to manually clean the bowl every week or two to keep the problem under control. I recently decided to try out the blue cartridges to see how well they worked and see if there was any difference. To my surprise it seems as though the blue detergent cartridges are doing a better job at controlling the mildew under the rim of my toilet than the white chlorine cartridges were. My water supply tends to be heavy in minerals (particularly calcium) and it is treated strongly with chlorine/chloramine. It seems both the white and blue cartridge work well but their effectiveness might depend on how chlorinated your water supply already is and what type of growth or deposits you are getting in your toilet bowl. Conclusion: I recommend that users of the Fluidmaster system test both types or try alternating both types of cleaning cartridges and see which works best for your particular situation. As a plus the blue detergent cartridges are less expensive but unfortunately they do need to be replaced more often than the bleach ones which for me last up to four months. I would also suggest installing a fill valve with a system to control the flow of wasted excess water from overfilling the bowl. I am using the HydroClean HC660 fill valve with a built in water bowl overflow control but Fluidmaster also sells a good system that can be added on to an existing fill valve and adapted with an adjustable pinch roller with pressure clamps that slide on tubing between the fill valve and the Flush and Sparkle system (or use the complete kit, Fluidmaster 400ARHR High Performance Toilet Fill Valve). These help control how much water flows through the cartridge cleaning system so that your cleaner and water mixture doesn't just flow down the drain along with excess wasted water.

This is going to be a long review. First off, let me say i have been using this product for years. I actually stockpiled several refills years ago when my local hardware store decided to stop selling them. I relied on these very heavily because my water is very hard and it helped keep my bowl clean between manual cleanings so I don't need to spend as much time cleaning calcified deposits out of the bowl. I really liked them, even though they were expensive and never got the amount of time out of a cartridge that i hoped. This year i used up the last of my stockpiled cartridges and ordered these (same model number). Immediately i could tell a difference. Previously, when i first installed a cartridge, the water would be so blue it would be almost opaque. The cleaning action was good too. When i installed this new one, the blue dye was faint, almost at the level of 4 weeks use on the old ones. The blue dye is cosmetic, so i figured there was a formula change and waited to see how well it worked. After only a month there was very little color left, and it definitely wasn't doing the cleaning job well (was back to alot of manual labor to clean the bowel). I contacted the company. They said there was no change in the product formula, and sent me two replacement cartridges and a prepaid box to return the one unused cartridge from the box that I had a bad experience with. When I tried to remove the new cartridge from the dispenser (no longer any blue color and not working for cleaning) i found the dispenser was full of thick gooey blue sludge which was not dissolving easily. I removed the dispenser and rinsed it clean in the kitchen sink (took a long time). The new cartridge that the company sent me was better, but also CLEARLY different. The blue tint was again not anywhere near as dark as the older ones that i ran out of, but it was much better than the last one. So clearly, despite what the company says, the formulation HAS changed. This new one was helping to clean, unlike the last one. Today the blue dye was almost gone again, so i went to replace the cartridge. I pulled it out and found that it wasn't empty, and again the dispenser was full of blue sludge (but not as bad as the last cartridge). Removing it and re-inserting it seems to have displaced the sludge enough that the cleaner is coming out with strong color again. I'm going to try this trick for the next few weeks when the dye fades again. It seems pretty clear that the formulation of this has changed, and the stuff turns into blue sludge (at least in hard water). I'm not sure what I'm going to do, because, as i said, I really rely on these things. Maybe I'll try the bleach cartridges instead.

Always have a sparkling toilet bowl as long as I have these installed! They really work so very good!! Will always buy these!!

This works exactly as described. Installation was quick and simple, and it fits nicely inside the tank without getting in the way. Once installed, it automatically cleans and freshens the toilet with every flush, which is super convenient. I like that the cleaner is hidden inside the tank, so there’s no bulky device hanging in the bowl. It keeps the toilet smelling fresh and helps prevent buildup between regular cleanings.

Purchased this from Amazon US as they are not available in Australia even tho Fluidmaster toilet cistern spares are,I spoke with Fluidmaster here in Australia told him i had a Coroma float in my cistern and he told me how to make it work for the Fluidmaster device. It works as is described in the brochure/ add but the colour/cleaner cartridge seems to clog up and doesn't allow the product to dispense. Searching through my shed i found a Fluidmaster valve and float assembly purchased as a replacement along time back but never got around to using it, I will install this in my cistern although the operation appears to be the same hookup as the Coroma float, If it works I will modify this review to reflect same.

Love these but a bit expensive for just 2 refills.

I bought the starter kit with the white chlorine version. It worked well; the chlorine starter insert did a great job and lasted 3 months. I bought the blue refills afterward. The blue inserts last about 2-3 weeks. They do work well for 3 weeks. Although 35 dollars for 6 weeks of clean toilets seems a bit outlandish. I will go back to the white chlorine version as they are fantastic.

Have purchased the clear refills in the past. First time purchasing the blue tinted refill. The price offered from this supplier was more economical than the clear. Keeps the bowl clean and free of stains. Note these are refills only and require the fluidmaster toilet bowl cleaning system.

These work great but they can vary in time they last depending on frequency of flushes; obviously. However, if you have several toilets in your house and you leave one for several days without flushing, the water will be concentrated with this cleaner and may be clumpy or gel like. Just flush several times and it will clear. It has left blue stains on the toilet bowl but it can easily wipe off.
