When traveling, once every week or two I clean the front, at least the mask part, headlights, mirror backs, etc., and apply a simple spray-and-wipe silicone or wax treatment. If more ambitious, I get up and do the brow once in awhile. I do it during a leisurely period of the stay and when the sun isn't hard shining on it, so it is relatively quick and easy. Cleaning off the bugs then becomes a heck of a lot less work.
