Fluidmaster Flush 'n Sparkle Automatic Toilet Bowl Cleaning System Bleach Refill Cartridges - White Finish, 2-Pack

When they first came out, I converted all my toilets to accommodate them and they were a lot cheaper. I could get them at Home Depot for a lot cheaper and they were always in stock. Now, they're hard to find and cost way more than they used to, but they work. It's the only safe way to introduce bleach into your toilets without harming your seals or causing any damage to your internals. It's the greatest invention since sliced bread, but now hard to find and costly.

So glad these exist. Keeps the ol' bowl clean and fresh without the hassle of those other, silly, drop-in tank jiggers. Slight bleach smell, but to me that's a positive.

Found this product a few years ago while buying new parts for a toilet that had been destroyed by other toilet tablets. This one was created by plumbers and does not corrode internal toilet parts. It keeps the toilet clean for literally months.

The worst thing about housekeeping is Cleaning the Toilets. This product does it for you! Best thing since sliced bread!! I prefer the Bleach type as the ‘blue' doesn't seem to clean as well.

Works perfectly and saves you from manually scrubbing your toilet!! Fresh bleach small and easy to assemble and replace every 3 months. You can even set-up for a refill reminder.

such an easy system %26 it does no harm to the mechanics of my commode unlike other tablets that go directly into the tank.

Once you get it in the tank this is by-far the easiest way to reduce iron/rust and other stains in your bowl, without soaking your rubber washers and flapper in harsh beach.

The bleach tablets that go into your tank will damage the plastics. I know because I came home on day to find the house with water soaked carpets. The bleach tablets I used in take eat thru the stand pipe .And it broke causing water to over fill toilet . I like clean toilets . So I found this Fluidmaster injector system #8300 Flush'nsparkle cleaning system. It is easy. Buy the kit. Takes 2 Minutes to install. Then when you flush the bleach injects into the bowl only. And keeps it very clean. Must clean first the just use these replacement cartridges every 34 months. Very easy to change. 30 seconds. A must use product. I don't like cleaning toilets This does it for me.

Have used "Flush 'n Sparkle" for several years, originally purchased at Lowes. However, Lowes has recently discontinued item along with refill cartridges. Thankfully, Walmart has item at similar cost available online. Product works well for 3 to 4 months without damaging internal tank parts like in the tank chlorine tablets.

Exactly what we needed and it works. Two fit well with the filter and two dribbled a bit. Two toilets are flush against the wall and I had to glue the filter to the tank.
