White vinegar and baking soda make an effective, inexpensive cleanser for sinks, countertops and toilets.
In a pinch, create your own buttermilk by adding a few tablespoons of lemon juice or vinegar to a cup of room temperature milk or cream. (stir after thickening)
When mixing cornbread, use the leftover batter as a beauty treatment. Scrape the inside of your mixing bowl. With your hands over the sink, scrub the cornbread batter onto your hands and wrists, then rinse. The cornmeal is a natural exfoliate and the milk, eggs, and oil are moisturizing to the skin.
