Features
- Continuous Automatic Cleaning & Freshness: Transform every flush into a powerful cleaning action. These blue tablets automatically scrub the bowl, preventing grime buildup and eliminating odors at the source. Experience a consistently sparkling bathroom with a refreshing "Fresh Rain" scent that lingers without being overpowering.
- 18-Pack Bulk Value & Ultra-Long Lasting: Designed for high-frequency households, this 18-count supply provides 6 months of maintenance-free cleaning. Each tablet features a slow-release formula that lasts significantly longer than standard alternatives, ensuring your tank remains effective and your bowl stays blue for up to 10-15 days per tablet.
- Advanced Descaling for Hard Water Areas: Specifically formulated to tackle the toughest bathroom challenges, including hard water stains, lime scale, and mineral deposits. The powerful descaling agents break down "invisible" buildup in the rim and jet holes, maintaining optimal flushing power and preventing future ring stains.
- Septic-Safe & Plumbing-Friendly Formula: Clean with peace of mind. Our non-corrosive formula has been rigorously tested to ensure it is safe for all septic systems and internal components. It effectively cleans and deodorizes without damaging rubber seals or metal valves, thereby extending the life of your piping equipment.
- Effortless "Drop-in" Maintenance: No scrubbing or heavy lifting required. Simply drop one tablet into the corner of the water tank away from the outlet. The tablet dissolves evenly to provide a professional-grade clean that reaches areas brushes can't, making it the ideal solution for busy families and commercial properties.

Easy to use—just drop it in the tank and it starts working. Keeps the bowl looking clean with a consistent light blue tint in the water. Helps reduce buildup and keeps things fresher between deeper cleans. Scent is light and not overpowering. Overall a convenient, good quality option.

I like that they are made of natural ingredients that supposedly will not ruin your plumbing. I was using tabs with chemicals and bleach and now one of my toilets the seal on the valve has started to leak and the toilet keeps running and I need to get it repaired. I was not using those on the toilet that I was not using a lot and now I am using that toilet all the time with these to test them out. I have only been using these for a month and they smell decent and do not seem to keep the toilet as clean as the ones with bleach at least not as long and they do get used up in 2 or 3 weeks. But the tabs I was using with bleach did not last 6 months like they say either, maybe a month and a half or 2 months and like these you still need to clean your toilets regularly but they do allow you to not have to clean as often.

Unfortunately, this product did not work out for me. They clumped up in the tank and the blue only last for a few flushes, each tablet does not last for days, let alone weeks. I don't think the cleaning power is there. The quality needs improvement. I missed the return window on the previous version which was really bad. This newer version works slightly better, but still needs some work. Had to return it, but thank you for the opportunity to try it out.

These work really well to keep the bowl clean in between scrubbings. They do get used up pretty fast depending on the amount of flushes or how busy the location used in is.

I bought these Automatic Toilet Bowl Cleaner Tablets because they looked decent and were reasonably priced. At first, like most people, I would just take a tablet out of its package, and drop it into the toilet tank. However, I got frustrated because the blue gel hardly came out into the toilet bowl. However, when it came out it came out in heavy, dark blue, and chunky quantities. I carefully examined the situation. I found that due to the position of the tablet being at the bottom of the tank and the gel which it releases is much heavier than water, the gel would usually be unevenly released and most of it stayed at the bottom of the tank. The colored water usually doesn’t come out until most of the tablet has been melted into the tank. To resolve this problem, I designed a simple device to reposition the tablet inside the tank. See the photos provided here. I took two used plastic food containers/cups, drilled or poke holes around them, both on the sides and the bottoms, then connected the two containers with a twister tie. And finally, I filled in the top cup with a few rocks, and placed the device into the toilet tank. Each time when I want to use an Automatic Toilet Bowl Cleaner Tablet, I’d just drop one into the top cup. Voila! This resolved my problem with the uneven release of the blue gel! And the end result is what you see in the first photo attached. In my experience, since I’ve started to use my homemade device, each tablet has lasted between 7 to 10 days (in a 3-person household). I would buy these Automatic Toilet Bowl Cleaner Tablets again and recommend them to other customers.
