When I had my business I decided to try to build a chip cleaning machine. It was air powered and worked pretty well. Of course I needed a liquid cleaner for the machine so I tested lots of products. The one that worked the best was the daily shower cleaner. Did a great job and did not seem to hurt the hot stamps. My machine was a very crude version of what I hoped to produce but never did. It would automatically get a chip from the stack and take it to the cleaning station where the chip was cleaned then ejected from the machine.
