Hi John,
It was in a poker mag(Card Player or Bluff?) back around JanuaryI believe.I read it when I was in Vegas at that time.I am sure that there are other members who may have read the same article.
If I remember correctly,the Wynn had the cleanest chips and all of the others had gross disgusting bacteria on them.Hmmmm....just went to the net and found the link.
Read it and then go buy some chip cleaner:
