When I clean on a 401, I use the piks a lot. I usually end up poking paper towel pieces in nasty places so that it will absorb the solvent when I'm using a toothbrush or something that is a less controlled application. It's easy to get the paper out with a dental pik. Also, I use them sometimes to get the end of a strip of t-shirt material around a shaft, so that I can clean the back side.
