About Flush Frog
Flush Frog started with a plumbing question, not a cleaning slogan: why put cleaner in the entire toilet tank when the part you are trying to keep clean is the bowl?
The small tube that changed the idea
Inside most gravity-toilet tanks is a thin refill tube. After a flush, that tube sends a small stream of water into the overflow pipe. The water does not stay in the tank. It travels through the toilet’s internal passages and refills the bowl.
That means a standard toilet already has a dedicated water path from the fill valve to the bowl. Once I understood that path, the product idea became much simpler: use the bowl-refill stream as the delivery route.
Why I invented it
I was looking at ordinary drop-in toilet cleaners and kept coming back to the same mismatch. The visible problem is usually at the bowl waterline, but a tank tablet spends its time dissolved around the working parts inside the tank. I wanted a way to automate bowl maintenance without making the whole tank the dosing chamber.
Flush Frog clips onto the overflow pipe and routes refill water through a small dispenser. After a flush, the same water that was already headed toward the bowl picks up cleaner on the way.
What Flush Frog is, and what it is not
- It is a clip-on dispenser for compatible gravity toilets.
- It uses the existing refill tube and overflow-pipe path.
- It is not a tablet dropped into the tank.
- It is not a hanging bowl puck.
- Cleaning tablets are sold separately.

The approach
The goal of this site is to explain the mechanism plainly, show the limitations, and help you decide whether the product fits your toilet before you buy it. That includes telling you when Flush Frog is not the right answer.
