While you may not think you have to clean your can opener often, rust and gunk on the can opener can prevent its gears from working properly. Fix a dirty can opener by soaking it in white vinegar to loosen all the dirt and rust. Then, scrub it with a toothbrush to remove gunk from the gears. If you have an electric can opener, then detach the blade bracket and soak it in white vinegar as well. Prevent further rust buildups by using a stainless steel can opener and drying it after every use.
