Most of the dishwashing liquids you can buy at drug stores are cap type. When you put it out, you need to hold it with the opposite hand to the sponge and turn it upside down, which is a little troublesome.
Some people may have transferred to a commercially available pump bottle, but I found an item that can be easily pumped at the 100-yen shop "Watts", so I will introduce it.
"Dishwashing liquid pump" developed by a manufacturer called Hoon. In addition to the pump and straw, two types of attachments are included, and one product is compatible with bottles with diameters of approximately 23 mm, 25 mm, and 27 mm.
When using, just cut the straw according to the size of the bottle, remove the original cap and replace it. When I tried it with three major manufacturers, "JOY", "Cucut", and "Charmy Magica", I was able to install them without any problems.
The annoying writer often pushes with a hand holding a sponge, so I got the impression that it would be easier to push if the top surface of the pump was a little flatter. Also, since the pump is white, you may notice the difference in color when you attach it to a colorful bottle.
However, it is convenient to use the same one even if you change the detergent. I want to hurry and change the current detergent bottle! Why don't you consider it?
