Exploring ways to reuse coffee grounds is a hobby of some coffee drinkers. Adding coffee to gardens or compost piles is a common use for these remnants of the energy intensive process that delivers the exquisite tastes and aromas enjoyed by coffee connoisseurs. However, what if you’re not a gardener or you only have so much garden space? I tested a few other things you can do with used coffee grounds, to help remedy this problem. All the uses mentioned were done with ordinary brand name used grounds.
You can simply brew them again. Wait until they dry, and you will need to alter your usual grounds to water ratio, but it works well with a little experimentation.
Coffee is a natural deodorizer. Dry out coffee grounds, place in a small fabric bag or satchel, and then hang in a spot, such as a car, that need deodorizing.
I made a marinade using used coffee grounds and olive oil for my traditional Memorial Day lamb steak, using coffee grounds from a dark roast brew. I let the steak marinate in the fridge for a day. It resulted in a hint of coffee flavor and a very tender steak. Read about similar uses over at the recipe section of Talk about coffee.
Perhaps the most useful thing I found you could do with used coffee grounds is keep the fleas off pets A friend told me of this method and I admit, I was skeptical. That is, until I tried it. I can personally attest to this method only for cats. I bathed the cat, an experience in itself, and then rubbed the used coffee grounds in its coat while it was still wet. I did this three times a week for two weeks on a cat that had been plagued half the summer. After the second application, fleas seemed to run from my formerly bewildered feline. The only drawback was some coffee grounds turning up in places like the cats’ favorite chair. This was a small trade off for a flea free, sweet smelling cat.
Not everything works like it should
One use I heard of that did not work for me was keeping rodents out of a garden. Specifically, I had a huge problem with groundhogs. I first sprinkled used coffee grounds around the potato plants they liked so much. This did not work. So, I tried mounds of the grounds around the plants. The groundhogs seemed not only undeterred, but I even witnessed one munching on the mounds as an appetizer to the prized potatoes!
With some investigating, you will discover many other ways to reuse coffee grounds coffee grounds. These are just a few that I tried. Good luck with finding of your own, after all, re-using, next to not using, is one of the greenest things we can do.
