The author cleans the washbasin once a week. The drain pipe is cleaned with a brush within reach, but what's happening in the back? I imagined that it would be very dirty, but I didn't take any measures because of the invisible things.
At that time, I saw a cleaning item called "Raku Hapi Mach Bubble Bubbleoon Washbasin Drainage Pipe " (Earth Pharmaceutical Co., Ltd.). It seems easy to use, so I decided to give it a try.
"Raku Hapi Mach Foam Bubbleoon Washbasin Drainage Pipe" is a cleaning agent (neutral) for the drainage pipe of the washbasin that says "New concept Mach foam cleaning!". It is explained that Mach foam can be used to wash away dirt and clogging, and to wash, deodorize, and sterilize deep inside the washbasin.
Very easy to use. First, shake the can well and turn the nozzle in the direction of OPEN to unlock. Turn it upside down and press it against the drain with the faucet removed. Then a large amount of bubbles gushes out. While I was sick, the bubbles reached the overflow hole and flowed out with the dirt. The guideline for injection is about 3 to 7 seconds. The unfamiliar writer has sprayed a little too much.
You can flush it as it is to finish cleaning, but if you want to thoroughly clean, deodorize, and sterilize by penetrating, leave it for about 30 minutes without flushing it. Although it is necessary to ventilate, there is a sense of security because it does not use chlorine and does not have a strong odor.
Well, after 30 minutes, if you look closely at the place where the bubbles of Mokomoko are crushed ... I noticed that a huge black sludge mass was coming out and pulled it. It seems that it was steadily accumulating in the back of the drainage pipe that could not be cleaned. It was really nice to be able to get rid of such dirt! It was easy and I got a visible effect, and it was a very satisfying cleaning.
It's a very simple "Raku Hapi Mach Bubble Bubbleoon washbasin drain pipe", but there is one caveat. When you press it against the drain and spray it, the bottom of the can and the faucet may hit each other and you may not be able to do it well. The height of the can is about 201 mm. Before you buy, it's a good idea to make sure there is enough distance between the faucet and the drain.
Each bottle contains 200 mL and can be used 2 to 3 times. It is available at supermarkets and mail-order sites, and the selling price is around 650-700 yen. Why don't you use it for cleaning the drain pipe of the washbasin, which you are curious about but cannot easily do? There may be awesome chunks that you don't even know what they are made of.
