Needless to say, the thermos brand "Thermos". The author is also indebted to the high heat retention all year round.

However, the drawback is that stainless steel bottles are difficult to wash. Often it's a hassle and you just have to wash it with water. Especially when you put tea-based drinks, isn't the inside brown without you noticing it?


From that Thermos, a washer for stainless steel bottles was released on August 21st. The price is 3,000 yen (excluding tax).


This product is a set of a cleaning device for stainless steel bottles and an oxygen-based bleach for trial use. Speaking of oxygen bleach , it is a natural detergent that I introduced in Enuchi before, but it took about 30 minutes to soak it when removing tea astringency. However, if you use this, you can wash it more powerfully in just 3 minutes! I would like to try it immediately using the brown bottle I mentioned earlier.


◆ What kind of mechanism is it?

The set includes a round device, a metal rod, oxygen bleach and a measuring spoon. Use a dry battery (sold separately) in the device.


There is a metal wire on the back side of the device, and by covering it with the mouth of the bottle, electric current is transmitted inside. Then, a chemical reaction occurs between the bottle and the dirt, and the oxygen-based bleach lifts the dirt from the root and peels it off!


First, add bleach according to the capacity of the bottle and pour water about 2 cm below the mouth of the bottle.



After stirring well, place the device with the metal rod in your mouth and push the rod to the bottom.



All you have to do is press the switch and wait 3 minutes. The lamp lights up, but there is no sound at all. I'm worried if it's really moving, but when I lift it, it stops, so I'm patient.


◆ Sewage like tea ...

When the lamp goes out, take out the contents ... What a brown!


On the other hand, if you rinse the bottle and look into it, it will be shiny! It's like new!


◆ Can it be used only for thermos?

My bottle washer is very convenient because it can be left for 3 minutes, so you can do household chores with just one hand. Not limited to thermos products, it seems that it can be used for products that meet the conditions of "capacity 800 ml or less", "caliber 7 cm or less", and "metal mouth". However, it cannot be used for those with fluorine or ceramic coating on the inside, or those made of resin. Also, since it cannot be washed with water alone, use it together with oxygen-based bleach such as "Bleach for Thermos My Bottle Washer".

By the way, according to the person in charge of thermos, the ideal care method is to wash with a sponge every day and bleach once a week. If you use "chlorine bleach" for thermos, it will cause rust, so be careful! Please use it properly for a long time and comfortably.
