Why dry your hands out with a solution that is made to remove grease

stuff can only remove just so much dirt before it becomes
Use a “foot file” (those files you find in the foot care section of
the drugstore that are meant for removing callouses on your feet) to
remove the polishing dirt from your fingers at the end of the day.
The noise they make is very likely harmful to our hearing. I’ve
encircled my ultrasonic with a barrier of thick rubber. It makes it
slightly difficult to get in and out of the thing but it helps with the noise.
