here is the easiest way... there is something called a degasser... you can get them at the auto parts store... it is something that you can use to magnetize the end of your screwdriver... if you turn it one way... it magnetizes and the other way demagnetizes... this will remove the magnetism and should come off real easy... I have one in my toolbox if you need to borrow it...:-) However some of the other ideas sound fun...:-)
