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

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.

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.

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.

Never received this item.. Will reorder

Minor issue with getting it to hang on the back of the tank. It was conflicting with the lid, but I had the slot on tank to put it in.

Great product works wonderfully!

It doesn't quite last 3 months as advertised but close. Don't buy the blue alternative, that's garbage that clogs up and creates a mess.

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.
