Mosquito Spray - worth a try. Pinner says, "I was at a deck party awhile back, and the bugs were having a ball biting everyone. A man at the party sprayed the lawn and deck floor with Listerine, and the little demons disappeared. The next year I filled a 4-ounce spray bottle and used it around my seat whenever I saw mosquitoes. And voila! That worked as well."
To clean a cast iron skillet, scrub it with coarse salt and a soft sponge. The salt, a natural abrasive, absorbs oil and lifts away bits of food while preserving the pans seasoning. Rinse away salt and wipe dry.
