Probably a related compound to oil of wintergreen. "Rubber Renue" was another such stuff--basically OoWG and Xylene Smells nice. The biker community seems to like it to refurb rubber parts, either mixed with xylene, or hot water or isopropanol. Worth a little more experimenting. The rest of the drive is near-pristine, not even any dust inside. I'm driving it with a STM32F407 MCU. --Chuck
