Angry Face

Hello, I'm an active member of another community about the spinning tops game, Beyblade. I was recently informed that a free-spinning part made out of polycarbonate and released exclusively by a particular brand might be coated in some kind of dry lubricant, possibly Teflon/PTFE. As such, I'd like to test the surface of this part for the presence of a dry lubricant, ideally without destroying the plastic. However, I have no idea how I might go about this process. I spoke with a friend about this and he recommended that I look to the Nerf community for assistance. With a little research, I found this forum, which, while being very informative on the effects of various types of lubricant on different plastics, I've been unable to locate any insight on how to determine the presence of dry lubrication, specifically Teflon/PTFE.

Please excuse me for posting a question rather unrelated to Nerf, but I was told that you guys are the most knowledgeable community when it comes to dry lubricants. Any and all help is very much appreciated, thank you.
