Beginners Polo

soak it in ammonia - it worked on my seatpost once. Not sure of the princicple though - i think it needs to be two different types of metal that have bonded so if your pedal axle and crank is the same it might not work.

Oooo, Where do you get ammonia from? I have no idea what metals they each are but the pedals have rusted far more than anything else on the bike.
