Wax paper is a staple item in every serious baker's kitchen, since it helps out immensely with many pre- and post-baking tasks, and cooks love to use it too since it's cheap, non-stick and similarly handy during prep.
But that's not all you can do with wax paper in the kitchen- you can also rub it on your faucets to keep them spot free and shiny, and you can use wax paper to seal and buff your wooden utensils too.
Outside of the kitchen you can rub wax paper on zippers to prevent them from sticking, and you can rub it on the soleplate of your iron and on your curtain rods to keep them gliding smoothly. When it comes to wax paper smooth is the name of the game!
