I’ll be jiggered! I mentioned mum probably shouldn’t toss the coffee grounds down the drain and she told me one of her aunt’s said it was a good thing to do. Well, I looked it up and she’s right! (To an extent.) It appears used coffee grounds are one of the world’s most useful waste products. There are places all over the web dedicated to ‘amazing uses for used coffee grounds’.
I scribbled down just a few of the ideas to share (and if you don’t have any of your own, some coffee vendors will give you free bags of used grounds.):
One of the more popular uses for grounds is in the garden. I didn’t know how versatile they actually were! They attract worms (curious to see how caffeinated worms might dangle on a hook!), they repel gastropods and some bugs, the grounds are great for growing carrots and mushrooms, and excellent for composting.
They can be used to deice walkways, can be added to shampoo as a flea bath for your pets (caffeinate your cat, not sure that is a good idea!), and to use as an air freshener (this is accomplished by putting used grounds into a bit of panty hose or with wax to make candles).
You can use the grounds for craft projects from dyes to paints and playdough. (I’ve made a lot of different kinds of ‘play dough’ for kids, but I never thought to use coffee grounds in the pliable toy. I’ve never been fond of caffeinated kids.) It is also useful as a cleanser for almost anything. There are recipes for body scrubs, soaps (caffeine can be absorbed thru the skin!), it is thought to help remove cellulite, using it before you shampoo helps strip the hair strands of yucky things, and somehow, if you paste the coffee grounds on the bags under your eyes, it is supposed to help remove them.
You can use the stuff to clean stubborn stains on dishes and anything which can handle light abrasives. It is supposed to be a wonder solution to clean a fireplace. They can be used in place of baking soda in the fridge (and then, eventually, used again when dumped in the garden). Coffee grounds can be used to help clear drains.
Directions are to dump the used coffee grounds down the drain followed with a couple of drops of dish soap (kinds vary, but I bet Dawn is the best choice) and a pot of hot water (weak sink coffee?). Sounds pretty simple, but I might just try it. At least til I can get a hold of the lye solution at the store. At any rate, if there is another sewage flood in the basement, it will smell different!
