When you press it, the detergent will come out from inside ♪ Introducing the brush "Push Wash" found at Daiso, a 100-yen shop.
A kitchen brush with a container on the top for holding liquid detergent. If you put the detergent inside, put the lid on, and press the button "PUSH", a hole on the bottom of the container will open so that the detergent will flow down.
When I used it to wash the frying pan, the detergent came out properly and I was able to wash it while whipping it well. Since the bristles of the brush are hard, it seems to be suitable for cleaning dishes and cooking utensils that are not easily damaged, as well as for cleaning tiles in sinks and bathrooms. There is also a bottleneck that it is difficult to determine the appropriate amount because the detergent comes out from directly under the brush. Be careful not to push the button too much until you get used to it so that you don't put it out too much.
The price is 108 yen (tax included). It's not essential, but it's a little useful item, so why not put it on standby in the kitchen or bathroom?
