A fool proof way to remove small and large screws. The culprit in removing steel screws from aluminum is aluminum oxide. Aluminum oxide is like concrete, as we all know! To defeat this aluminum oxide you need a small torch and a block of beeswax. Heat the screw and melt beeswax into the screw joint. The heat breaks the aluminum oxide and draws the beeswax into the joint lubricating it and permitting removal of the screw. Use never seize on reassembly for a permanent solution
to an ever present PIA problem. This little trick hasn't failed me once in 35 years.
