If it is relevant for someone else, the best way to remove the pedal is while you have both crank arms on the bike. Take a piece of rope and wrap the opposite crank arm together with chain stay tube (many turns). Then a good wrench and a pipe, if needed, and the pedal will go off. This method never failed in my life and I have removed hundreds of stuck pedals. The downside is that most of the time thread in aluminium crank is damaged. But this will get your pedals off.
