If your fibers are dusty or dirty, you can clean them with a rag and some silicone lubricant. The silicone lubricant also helps prevent tangling and keeps FiberFlies playing smoothy. Put a small dab on a clean rag, and wipe it along the fibers from the base to the tips several times while simultaneously combing them with your fingers.
Make sure you use silicone & not another type of lubricant, e.g. glycerin-based lubricants can get sticky over time. Silicone lubricant also acts as a mild cleaner for the fibers, and we suggest using personal lubricant for the best results. We checked with the folks at FiberFlies LLC, and coconut oil should work as well.
Here is a link to our preferred lubricant, which you can order through Amazon.
