In the Garden
Not only can you use your used coffee grounds to fertalize your garden (azaleas, hydrangeas, rhododendrons, camellias, roses and other acid-loving plants will love your used coffee) they can also be used in your compost bin as they make excellent "green" matter due to being rich in nitrogen. (Be careful not to throw of the balance by adding too much in)
Add water or coconut oil to your used coffee grounds for the perfect natural skin exfoliant and reduce cellulite!
It might not sound to great but before your shower massage the used coffee grounds into your hair to restore shine and boost your hair's health.
Your used coffee grounds can also be used as a cleaning abrasive.
Simply save up your coffee grounds and scoop some into your next dirty pot or pan before hand washing, the grounds are absorbent thus perfect for greasy pans and the small jegged edges of each ground helps in cleaning even the grossest of dishware.
If you love to burn candles and the smell of coffee, why not combine the two and make your own candles?
