This is how i recently cleaned a rack of paulson chips.
I used two small containers, one i filled about 2 inches of water and put enough "BON-AMI" cleanser in it so that the bottom of the container had sort of a paste laying on the bottom, then just put so many chips in there, about ten or so, let them soak for a few minutes, then using an old tooth brush started to scrub away and it worked great, when i was satisfied it was clean i then used the second container for the rinse off.
On a side note, the concentric circle, i used a miniature utility knife which is very tiny and the blade fit perfectly to go around the edge and get the crud out of this area of the chip.
