Instructions
Remove the pewter lid from your ceramic beer stein with a screwdriver or awl, depending upon whether it is held to the lid bracket with a screw or a pin. Fill a small cooking pot or saucepan about halfway with water and boil the water.
Immerse the pewter lid in the water and allow it to remain immersed for about 20 minutes. Remove the lid with your gloved hands and place it on a flat work surface.
Try to straighten the bent lid with your gloved hands. This should be possible if the bend is around the rim of the lid.
Wrap leather or heavy fabric around the end of a metal rod if you are unable to remove the dent by hand. Lay the wrapped end against the inside of the bent surface if it is bent inward, or the outside if it is bent outward. Tap the wrapped end of the rod lightly with a ball peen hammer and check your progress after a couple of taps. Continue to tap the bend out of the lid as you see progress, but do not tap too hard or too many times.
Cover one end of a wooden block, about the width of the lid, with leather or a heavy fabric. Place the lid on the covered end with the bend facing up. Place leather or heavy fabric on top of the bend and tap gently with a ball peen hammer to finish straightening the bend.
Polish and buff the pewter lid with "all-metal" or pewter polish according to the instructions on the product package. Re-attach the lid to the beer stein.
