Automatic Toilet Tank Cleaning Capsule — Single
- Free US shipping over $40
- Tracked from the moment it ships
- 30 days to return it
One capsule for one toilet. Drop it into a corner of the tank and the mineral deposits that normally turn into rings and crust simply stop forming.
There is nothing to plug in and nothing to refill. The treatment is chemical-free, so the rubber and plastic parts inside the tank are left alone, and it carries a 10-year working life. For most households that means the toilet brush stops being part of the weekly routine.
Best choice if you want to try it on the one toilet that gives you the most trouble.

Start with the toilet that bothers you most
A single capsule for a single tank. If you want to see the difference before covering the whole house, this is the one to buy — it is the same unit as in the multi-packs, just on its own.
Why it works
The capsule keeps working for a decade with nothing to refill or replace.
Safe around children, pets and septic systems, and gentle on the parts inside the tank.
Lift the lid, place it in a corner, close the lid. That is all there is to it.

What customers say
-
Impressive
The bowl stays spotless and the water sitting in it looks clear, even after a couple of days without a flush. I will be buying another one to give away.
-
Bought one to test it
Started with a single capsule for the guest bathroom, which is the one that always looked worst. It worked, so the rest of the house is getting one too.
-
Does what it says
No smell, nothing to plug in, nothing to remember. The ring that used to come back every fortnight has not returned.
