What should I use, if anything, to lube the teeth and gears on the underside of my 2 big slideouts? The smallest slide-out (bedroom) has no exposed gearing so I guess I can't do much with that one.
After brushing the teeth of the gears clean I spray on Teflon lube. In actuality, though, you don't have to lube at all. Just keep the teeth clean. I believe I read somewhere in the instructions that lube isn't necessary. I still spray some on because I feel it can't hurt and may be beneficial to a small extent. Just don't use anything that will attract dirt.
