Generally speaking, we don’t recommend washing old coffee grounds down the sink – not only will this set you up for a nasty clog, it’s a total waste of an awesome resource.
The jury is still out on whether or not you should use coffee grounds in your garden. There are some studies indicating that coffee grounds actually deter plant growth for certain plants (yikes!) – so… maybe use it as a weed killer instead. In fact, there’s some pretty good evidence for the use of used coffee grounds as a weed killer. Your mileage may vary.
Where coffee grounds really shine is to help you with odor control. Dried, used coffee grounds can deodorize funky gym bags, closets, and shoes (just put the coffee grounds in a mesh bag first unless you like the feeling of sand in your shoes!) for about 24 hours. It may not be as effective as baking soda, but for something you’d normally throw out anyway, it’s a way to get a little extra mileage out of your beans.
One last one – and this is our favorite – old coffee grounds plus coconut oil make a gentle, awesome-smelling exfoliant. Mix in a smidge of cocoa powder for a chocolatey boost and you’ve got a DIY spa-quality facial!
