When I was a boy, an older man taught me to lubricate the ends of the sections of my fishing pole with a little grease from the sides of my nose before I assembled the sections. Believe it or not, I simply rub the sides of my nose with a thumb and forefinger and rub the valve a bit before fitting the pump. Works great. Not only that, I pretty nearly always have my nose with me when I need to pump up a tire.
