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

These are very efficient. Tabs in the toilet tank deteriorate the tank seals. The tabs in the Kaboom never touch the tank water. The water that goes through these, goes directly into the bowl. If you have trouble finding replacement tabs, I've used 1" pool chlorinating tabs and I've taken a knife and hammer to any brand of toilet drop-in tabs. The latter, I cut up into quarters to fit into the Kaboom top. I've used these for many (10+) years and was very happy to find a two pack to replace the old brittle ones.

I have been using these for about 9 months and they work great. Definitely cut out the toilet ring that would start to form in 3 weeks to a month. Cleaning/scrubbing the toilet is not high on my fun list and I am as lazy as the next guy so any help with the toilet is very welcome. The install is super simple and easy. I bought tablets for pools/spas that are 1" and came in 1.5 lb container making the refills cheap. I bought choline ones so it can smell a bit but to me it helps make the bathroom seem cleaner. I guess you can buy Bromine tablets that have less of a scent.

Installation easy Have used for about a week and have not seen black water stains on toilet bowl since Hope works good over longer time

This is working well so far. I am only giving it 4 stars because I'm concerned about the durability. It seems a bit flimsy to withstand the water pressure it is subjected to while in use. I periodically check to be sure the tubes haven't popped off. They slide on/off easily and there are no ridges to "grab" the tubing. You can faintly smell chlorine/bleach smell when directly over the toilet. The product is clear when dispensed into the bowl. You have to start with a clean toilet. It seems like this is keeping it cleaner between scrubbings, but it will not replace a thorough scrub every so often. If you have pets, keep the lid closed - I'm sure it's not safe for them to drink!

We have finally found a product that keeps our toilets clean and the bathroom smelling fresh. Absolutely works great!!!

Bought 2 Kabooms for the toilets in mid December, 2025. Have used them for a month now. They keep the bowl clean, and there is NO chlorine smell as these do not contain chlorine. These are bromine tablets and are also used in spas and pools. I am buying generic tablets instead of the higher-priced Kaboom brand who another person recommended. They suggested Spa-Kem 267 and Tropiclear. I found Clearview tablets on Amazon at a good price. About .59 each tablet. They come in a 2# container.

Terrific product

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).
