Worked better than I expected, but not instant
I tried FizzClean after seeing it mentioned a few times online and decided to give it a shot since my toilet had stubborn buildup that regular cleaners never fully removed.
The first thing I noticed was how much foam it produced once it hit the water. I let it sit longer than the instructions suggested and didn’t scrub right away. After flushing, the bowl already looked noticeably cleaner, especially around the water line.
It didn’t completely erase years of neglect in one use, but after a second application a few days later, the difference was clear. Less odor, fewer stains, and overall it just looks easier to maintain now.
I wouldn’t call it magic, but it does what it claims if you’re patient and follow the directions. For me, it worked well enough that I’ll keep using it instead of harsher cleaners.
