Did you know that you can clean and protect your manual can opener with simple wax paper? It’s that easy! Here’s how to do it:
Fold a sheet of wax paper a few times; then clamp the can opener onto an edge of the wax paper and turn the handle several times—the same action you would use to open a can. The stiff sheet will break off bits of food and grime from the wheels of the can opener, and the wax residue will lightly lubricate the parts at the same time for smoother operation.
You may need to pass the wax paper through the can opener a few times to remove really tough gunk.
