I just read your "Chip Cleaning Tips" article (twice) on the board, thanks to Doug.

When I first started collecting in 1999 and started selling on I used to clean chips with the ArmorAll cleaner you mentioned in your article. Then I started reading and haven't cleaned a trader or a chip for sale since.
The exception is Chipco. I read here recently that Chipco says you can send them through the dishwasher.
(No I won't do that).

Thanks again.
