1. BATHTUB SCRUB

Formula: Grapefruit + Salt

How-To: You can always use baking soda and vinegar, but we prefer this fresh-smelling citrus combo for a spa-like vibe. Just sprinkle half a grapefruit liberally with salt, then wet your bathtub and sprinkle another ¼ cup salt around the perimeter. Use the grapefruit to scrub the tub, making sure to squeeze a little juice over your drain and faucet. Rinse away with lukewarm water.

How-To: In a bowl, mix ¼ cup olive oil with a few drops of apple cider vinegar. Dip a rag into the mixture and wipe down your furniture. The vinegar draws the dirt out, while the oil ensures the wood doesn’t get too dry.
