What is a foaming toilet cleaner?
There are two kinds: spray foam from a can or bottle that you apply from above, and powder that foams up in the bowl water. Fuugu Power Foamer is the second kind: a pre-measured pouch goes into the water, and according to the vendor the foam climbs the sides up under the rim.
Why foam instead of gel?
A cleaner only works while it's in contact with the deposit. Gel slides off the rim within seconds. Foam clings and stays put. And a powder foam that grows from the bottom up reaches under the rim without you having to apply anything there.
How long do you leave toilet foam in?
That depends on the product. For Fuugu, the vendor says about 20 minutes – then you flush. Leaving it overnight isn't necessary, according to the vendor. For other products, follow the label.
How often should you use it?
For Fuugu, the vendor recommends one pouch per toilet per week. New deposits get removed before they can grow into a crust. Old, thick buildup will need several weekly rounds at first.

Frequently asked questions
Does toilet foam really reach under the rim?
Foam that forms in the water and rises reaches the rim from below. According to the vendor, Fuugu's foam collects under the rim; the height varies with bowl shape and water level.
Can I leave toilet foam in overnight?
With Fuugu that isn't necessary, according to the vendor – you flush after about 20 minutes. Follow the directions on the package.
Is a foaming toilet cleaner worth it?
Mainly when limescale and urine scale build up under the rim and you don't want to scrub. For a light ring at the waterline, a home remedy often does the job.
