How do I open a stuck clean out valve?

Question: I can't remove my clean-out plug. How do I remove an old clean-out plug?

Answer: Use a steel chisel and a ball peen hammer on the face of the clean-out plug at a 45-degree pointing counter-clockwise. Increase the angle to get more turning force. If it's still stuck, chisel through the surface of the plug and cut the rest out with a sawzall. Use a heavy screw driver to pry out the threads.
