Ever had tuning problems like stuck pegs or pegs that will not stay put. This clear odourless synthetic oil will fix most of these problems. One drop drop will free up any stuck peg. The bottle contains enough to do thousands of tunings. This product completely evaporates over a few hours and leaves no residue. It is also brilliant to use on Guitar nuts and other sticking problems. It is safe to use as a lubricant to push loose pegs into the peg box to get better friction contact to stop slipping, as the product  totally evaporates over time the pegs will stay in their tuned position. This oil is non toxic and will not harm the environment.
