This year, I spend more time at home, and my home is a boom in cleaning. Suddenly, I noticed a place I had never cleaned since I moved.


It's a toilet water tank. According to the investigation, the inside of the tank tends to become a hotbed of germs that cause bad odors such as water stains, black mold, and yellowing. Actually, the washlet-integrated toilet bowl at my house has a specification that "the toilet tank does not open", but I am anxious because I can not see it.

Therefore, I decided to try a detergent that would not damage the tank as much as possible. This time, we would like to introduce Kimura Soap's "Toilet Tank Cleaning Powder".


"Toilet tank cleaning powder" sold by Kimura Soap's "eco friend" series is a toilet cleaning agent that does not use synthetic surfactants and is friendly to people and the environment. Pure soap fatty acid sodium is the main ingredient, and oxygen-based ingredients such as percarbonate and carbonate are blended.

One dose of detergent is divided into small portions, and after draining the water from the tank once, simply add it to the water supply from the hand-washing drain. After that, leave it for 2 hours or more and drain it again to complete the process. The part of the tank that is not submerged in water cannot be washed, so if the tank can be opened, scrub it with a cleaning brush after adding this agent.



After cleaning, the first flushed water showed something like an oil slick, but from the second time onwards it has returned to normal. Since the toilet cannot be used during cleaning, it is necessary to put it in before going out or going to bed, but there is no unpleasant odor, so is it so easy? It's easy to beat. It is also a nice point that the inside of the toilet bowl and the water pipe are also cleaned at the same time.

The manufacturer recommends regular use of one packet per week as a guide, and one box can be used eight times. For tanks that do not have a hand-washing function, the lid must be opened. It can be purchased at online shops, etc., and the price at the time of purchase is 990 yen (tax included). If you don't know what to use because it's a part you don't usually wash, why not give it a try?
