I started to notice that my trash didn't reek of old banana peels, leftover dinner scraps, or that withered broccoli I never ate. Then I realized the ground coffees were my own DIY odor remover.
So now I scrape out the grounds from the k-cup and spoon them into a little container. The container sits nicely in between the funky smelling kimchi jar and onion-y salsa eliminating all that odor. Works like a charm.
