Water in your keys? I spent a month looking for the best material to dry pads and I found it. In Korea.
These soft, extremely thin microfiber pad dryer cloths are quite simply the fastest, most effective, durable and inexpensive I could find. So I bought a ton of this material, cut it into strips for you to use, and am selling it for next to nothing.
For $2, you get almost three feet (a meter for everyone not from ‘murica or brit’n) of this stuff, in two strips. Just cut them to the size you want, and you’re good to go.
Machine-washable. Imported, by me.
