Using Fuugu in 4 steps
- Flush once. That clears loose dirt and brings the water to its normal level.
- Tear open a pouch and pour it in. Straight into the bowl water – no measuring, one pouch is one treatment.
- Close the lid and walk away. The foam forms right away and, according to the vendor, climbs the sides up under the rim.
- Flush after about 20 minutes. The loosened deposits go down with the water.

A plan for stubborn buildup
According to the vendor, heavy, years-old deposits may need a few weekly cycles. A realistic plan for a very dirty toilet:
| Week | What happens |
|---|---|
| 1 | First treatment. Thin films and discoloration come off; thick crusts start to loosen. |
| 2–3 | More treatments work on the deeper layers. Check under the rim with a hand mirror after flushing. |
| 4+ | One pouch a week as a routine, so nothing new can build up. |
How fast it goes depends on your water hardness and the type of deposit.

Fuugu Power Foamer: foam instead of scrubbing
According to the vendor, this foaming toilet cleaner dissolves limescale, urine scale and rust streaks all the way up under the rim – in about 20 minutes, no brush needed. Up to 70% off at the official store.
See the dealMore than one toilet?
One pouch covers one toilet for one week. Divide the number of pouches by the number of toilets: 8 pouches last two toilets a month, 12 pouches last three toilets a month.
What to avoid
- Don't mix Fuugu with other cleaners. If you just used another product, flush thoroughly first.
- Don't put it in the tank – Fuugu goes in the bowl.
- Keep pouches out of reach of children and pets, and follow the directions on the package.
- Don't rely on it to disinfect: according to the vendor, Fuugu is a cleaner, not a disinfectant.
Frequently asked questions
Do I need to brush afterwards?
According to the vendor, no – you simply flush after about 20 minutes. With very old crusts, take a quick look afterwards to see whether another round is needed.
Can I use the toilet while the foam works?
Better not. Give the foam its 20 minutes or so, then flush.
Does Fuugu work in cold water?
Yes. According to the vendor, the powder fully dissolves in cold and hard bowl water.
