First try: Any high performance penetrating oil will work. However it may take some time. Take out the Bottom Bracket and with the bike inverted, pour a "large" quantity of the penetrating liquid into the seat tube. This will attack the problem from the bottom. Let it work for a while; this may take days.
Second try : gets progressively more physical but depending on frame and your experience may be better to get someone else to do it for you.
