Beginners who have a problem remembering which way to turn the wrench when removing pedals should remember the saying "back off". No matter what side of the bike you are working on, right or left, you mount your wrench on the top side of the pedal bolt and then turn the wrench toward the back of the bike to remove the pedal ---"back off". Then just remember when replacing the pedal or adding a new pedal to turn the wrench forward to tighten. Make sure you mount the wrench from the top of the pedal or you will be working in the opposite direction. So remember 1) mount the wrench on top of the pedal bolt and 2) "back off"

Great tip, thanks!
