I have got a Logitech g9 for 6 years and it's works good but I have a problem with it's rubber coat because it's become sticky. I have the same problem with my qpad keyboard, keys aren't rubberized, but other parts are covered by rubber that's become sticky. Do you know a way to remove the rubber coat or at least the sticky part? And what can I use to safe cleaning rubberized mice and keyboards? I have always used antibacterial cleaner with microfiber wipes but someone says that isopropyl alcohol works better and doesn't ruin rubber.
