MY EXPERIENCE:
This sh** works! 
(I am not affiliated with this product in any way)
I read all the articles from the experts on how to safely clean collectible chips. I have purchased every product ever mentioned and tried them all. Many of them worked, but still required a lot of careful scrubbing. Some cleaned my chips, but changed the color slightly (not good). And virtually everything would take off a foil hot stamp with the slightest rub across the face of the chip (also not good). I tried the pink goop that is supposed to be "Magic". Well, it cleaned 20 beige chips wonderfully until I realized it had also "magically" tinted them slightly
pink (not good).
So I read a discussion on The ChipBoard (where some of the collectors hang out and chat) about this cleaner with great interest. Someone on the board volunteered to "sacrifice" some of his chips to the experiment and then posted his results. They looked great and he was happy so I figured why not.
The manufacturer makes chip cleaning machines ($6k+) and this cleaner and some other products for casinos. Jim at The Chip Room is the only retail source I know of and he's a nice guy. (Even if his website plays what sounds to me like obnoxious porno music) Sorry Jim.
I have gone through 2 bottles of the stuff and continue to be amazed by the results. I have spent my time at the kitchen sink with a baby toothbrush trying to clean chips so I didn't believe really dirty chips would come clean without scrubbing after only a 10 minute soak. Well they do!
I'll let you click on the links above to read more about the product. But I will give you a couple tips:
I found a small piece of microfiber dishcloth or shop rag worked best for wiping off the chips. Maybe because it had a little tooth to it? I also seemed to get better results when I wet the cloth with water and then wrung it out before using it. As it got more and more dirty, I just rinsed it out and kept wiping.
I keep 2 trays going while I'm watching a movie. I lay out 50 chips in the solution and after 15 minutes I take them out one at a time and wipe them off. When I begin wiping off the chips in the first tray I lay out my next batch in the second tray. When I'm done with Tray #1, the chips in Tray #2 have soaked and are ready to be wiped off. Refill Tray #1 and Repeat, repeat, repeat.
I learned that good condition hot stamps were not changed or harmed by the solution. However, an already damaged hot stamp might be harmed. For instance if it was already peeling or flaking, then it might fade or come off while I was wiping off the chip. But good hot stamps didn't change a bit, whereas with other methods they would wipe off immediately no matter how careful I was.
Keep your used solution in a container with a lid and just keep using it until it stops working. (And keep it separate from fresh solution, don't pour it back in the bottle) Try to ignore the disgusting gunk floating around in there, it still works even when it doesn't look so good. I poured mine through a coffee filter when I couldn't stand looking at the chunks anymore. Still worked great!
I even tested it by leaving a couple different kinds of chips in the solution
overnight. No harm done to the chips, hot stamps or inlays. You may need to leave really, really soiled chips to soak longer than the 10 minutes. When I clean white chips, I leave them in for 30 minutes. The finger jam just melts off and they wipe clean on the first pass.
Here's a link to the orginal discussion about this product on The ChipBoard:

and the 2nd experiment:

Here's a scan of my before and after. I realize it looks like 2 different shades of yellow, but they are the same chips. I think the scanner adjusted the color to compensate for the incredible brightness of the freshly cleaned chips.
Bottom line, I'm one picky consumer and I give this product a big thumbs up.
