I would not want to sterilize all my C&S chips this way and do not even THINK about touching a "paste on" in this manor or disaster will be inevidable! The CC chips I bought in a very large lot and they were all very nasty and now they are very nice clean classic chips ready and worthy of any collection. This lot of Ridge mold inlaids were a disaster area and they are now very nice rare collectable antique chips.
