Yeah well, that works sometimes; but you never can tell. If it's old and sticky there's no guarantee that it won't get gummed up again quickly. Face it, the lens is old and whatever lubricants in there have lost their volatile compounds. A little bit of heat from friction can loosen things up a bit, but the gunk will start to congeal again once it cools down. Then there's the issue of years of accumulated dust and other crap that has probably worked its way into the mix. Best to get it cleand up professionally. It shouldn't cost much, and you'll have a more reliable piece of gear in the end.
