When lids are stuck, follow these steps prior to using the lid lifter

  • spray perimeter of lid with penetrating oil
  • allow to sit for the period recommended by the manufacturer of the oil
  • using the blunt end of a heavy duty crowbar or heavy sledgehammer, strike the edge of the lid sharply at various points around the lid. This jarring action can help to break the seal
  • on a very stuck lid, do not attempt to lever up the lid with the lid lifter until the seal is broken
