Church And Dwight 35113" kaboom Scrub Free Toilet Cleaning System (Pack of 2)

They work like a charm. I have used these before in the past and cannot sing their praises enough. good bye to any buildup around the fill/drain holes in the bowl and good bye to any intense scrubbing. The power of the chlorine tablets used by the system ensures no staining to porcelain while also reducing the amount of any residue build up on the toilet bowl itself. They are not a substitute for regular bowl cleaning but they drastically reduce the amount of work involved.

So I like this design because it doesn't have tablet sitting in the water dissolving. This hooks up to the line inside the tank and only pushes water across the tablet when the tank is filling so the tablets last longer. We have had it installed for about 6 weeks no and there are not any black lines or rings forming, so this will keep us from scrubbing the toilet more often.

be aware that each box in the 3 pack only has one pouch ( 3 months supply) . when you get single, it comes with 2 pouches ( 6 months supply)

Works great.

Helps keep the potty bowl clean. Been using these for years. Love the product. The tabs last a long time.

I bought 4 and it really works! It keeps all the toilet clean. I add tablets every 2 to 3 months.

First off, for refills just buy brominator tablets, the cheapest you can find at a big box store. I've used Kaboom's for a long while. The tubing included is cheap but adequate, the filler valve 'hanger' included will rust and crack out so get a decent plastic one from somewhere else. However, this does what it says and keeps the bromine/chlorine away from the tank flapper valve so you don't destroy it as you would with just dropping a tablet in the tank. This bypasses that problem.

Had a written my review a few months ago, I probably would have given it 5 stars. I installed them in 2 toilets, one of which I scrubbed clean beforehand (as per the instructions). I chose not to scrub the other so I'd have a control, as it were. I'd read in other reviews about water leaking from the screw on lid, so I made sure to screw them on as tightly as I could, and never had any problems with that. A few weeks later, I made the following observations: 1. The pre-scrubbed toilet still looked surprisingly clean. Something about the water here causes a toilet bowl to quickly become discolored after cleaning; with the kaboom installed, that really didn't happen. 2. It's best to follow the instructions. The unscrubbed toilet didn't magically become sparklingly clean, though it did a good job of staying clean once I scrubbed it. 3. One of the toilets has lower water pressure for whatever reason. In this toilet, the kaboom lowered the water level in the bowl by at least .5 inches. There was no noticeable difference in the other toilet. 4. Of course the product is Scrub Free: it doesn't scrub, and it doesn't force you to scrub either. Depending on your standards of 'clean', however, you may still have to scrub. 5. There may have been a slight scent at the very beginning, but if there was, it either went away or I quickly got used to it.Over the next few months, some discoloration gradually built up, though nowhere near as quickly. The clear plastic tubes attaching the kabooms to the fill pipe became very cloudy, though water still passed through just fine. At about 3 months, the states of the toilets quickly worsened and it was clear that the tablets were gone. That seemed fair enough, since that was the advertised approximate lifespan of the tablets.Fast forward another 3 months. I finally decided to remove the kabooms from the toilets (since they weren't doing anything). With the water drained from the kabooms, I was surprised to find that both still had parts of a tablet remaining in them. I had been convinced (based on the state of the toilets) that there had been one left for 3 months. Whether or not it contains any of the 'active ingredient', it certainly hasn't been helping my toilets (or at least not noticeably).
