After you've brewed a cup of morning joe, don't toss the used grinds down the drain. Try soaking an old cotton T-shirt in cold coffee and wiping scratched tables to see the small nicks, dents and dings disappear. Or scrub your hands clean with old grinds and hand soap; the grinds will buff away dead skin, and the soap will make sure your hands are stain-free. Finally, try mixing old coffee grinds in the soil near acid-loving plants like dogwoods, hemlocks, blueberry bushes, hydrangeas and oak trees. The plants will thrive and love the extra jolt of nutrition.
