"Apple cider vinegar is my do-it-all," Mitchell said. (You can score this one from Bragg on Amazon for a cool $7.) "I'll use it to clean and I'll also put it in my water with a lemon. I've used it before on blemishes, but honestly, only when I've needed to get creative. It's a lot safer to use proper skincare products than to put household ingredients on your skin. But it is great for cleaning your house."
