Cleaning with metho is fine. Do it first though. Then, a good quality car wax is excellent for bearings. It is the stuff recommended by the Obsession mob too. It is applied to the laminate surface of the bearings, not the Teflon. It will help disolve and clean oils and dirt that the metho alone just can't. Any more specialized polish isn't worth the expense as good car waxes HAVE this silicon material in them. You can then easily justify the expense of a $30+ bottle of car wax to the missus,
, even if the car doesn't even get a whiff of the stuff.
Give the Teflon pad a clean too with metho. No wax on these!
I just did this to the altitude bearings of my 17.5" scope. It had been one year since the last touch up with the car wax - what a difference! I'll be doing the azimuth bearing this weekend.
Take your time with the cleaning with both the metho and the wax. The result is worth a little more time and effort.
I use the Turtle wax that comes in a small tub, and is scooped out. Just a little is needed.
