In my hometown, it's cold enough to have frost columns every morning, but I can't skip it even in winter. In such a season when you don't want to touch the water too much, why not just soak it in the water for "cleaning"?

This time, I will introduce how to use "oxygen-based" detergent, which is also attracting attention as a natural cleaning, to surprisingly clean places that you do not usually do much.


We prepared "oxygen bleach" and "washing tub cleaner" from additive-free soap maker Shabondama Soap. It has a milder bleaching power than chlorine, but it does not have a peculiar pungent odor and is gentle on the hands and the environment because it does not use synthetic surfactants (gloves for those with weak skin). Also, I often drop chlorine bleach on a patterned cloth to make white stains, but I don't have to worry about that.

[Refreshing] Stainless steel bottles with seasons are in new condition!

The first thing I tried was the stainless steel tumbler that I have been using in the office for about 3 years. The inside is beautifully dyed brown because chlorine bleach cannot be used and it was only washed with dish detergent.



Put 30 to 50 degrees of hot water in a tumbler to the last minute, add about 10 g of oxygen bleach, and leave it for 15 to 30 minutes. If you look closely, bubbles of oxygen will come out.


Throw away the water and rub it with a sponge ... what! It gives off a beautiful shine of silver! The smell is gone and it looks like new. I was impressed that it was originally such a color, but I wanted to do this and it seems that it will accumulate dirt for a while.


Oxygen bleach can be used for a variety of purposes, from bleaching clothes to removing tea astringency and cleaning bath kettles, so I'll try to clean it every week.


[Pleasure or reading caution system] Be careful not to take too much of the washing tub if you haven't washed it for a while!

Next is the washing tub. It is a place where detergent, protein, and water stains collect on the back side during daily washing and tend to become a hotbed for black mold and bikin. … Do you guys wash it properly?

By the way, I just cleaned it with a chlorine-based detergent a month ago at my house. Maybe it's wasteful? I will try it while thinking.


First, supply water to the washing tub to a high water level (30-40 degrees is optimal), add the entire amount of washing tub cleaner, and run for 3-4 minutes to dissolve. Turn off the power switch and leave it for 3 to 4 hours. After that, the "standard course" is operated for one cycle at a high water level.

If you look into it while it's left unattended, you can see it between the swelling bubbles ... oh. Something like black trash. Needless to say, this is dirt such as black mold.


When I start driving further ... dirty! Please note the following! I personally feel that the sensation of being able to take a sneak peek is close to that of an earpick (?), But I'm honestly horrified that I was washing clothes in such a dirty washing tub. Let's wash it once every 1-2 months!


By the way, the true identity of the "oxygen-based" component is sodium percarbonate. When it dissolves in water, it is decomposed into hydrogen peroxide and sodium carbonate, and oxygen is generated in this process, exerting a bleaching effect. It is an image that dirt is peeled off with bubbles.

Although I was refreshed for spring, it is important to clean it frequently regardless of the season.
