cooking wise, they're so bitter/burnt. The water already took the good flavor out of them and left the crap behind.

From the previous answers, it seems that using coffee as an abrasive or any other way will require a clean up after using the grinds, which in my opinion makes them useless.

Kills ants...dump them on the ant colony and they will die.

You can put it in a small dish inside your refrigerator. It will kill bad smalls and leaves a nice coffee smell. Note: Baking powder also works fine but without leaving any smell.

Put it in your ashtray and it will eliminate the smell.

A friend of mine (who lived in a van) always used it as a replacement for soap when washing hands. Seemed to work quite well :)

For those who collect kitchen scraps for composting, used coffee grounds are a great deodorizer for your compost pail, especially in large quantities (like if you do a batch of cold brew).

It's supposed to keep cats from crapping in your yard. Just toss it on the ground and apparantly they'll take their business elsewhere.

It's an abrasive. As long as you don't mind the coffee smell/stain, you can use it to clean and polish surfaces.

I myself use it as a universal scrub. Coffee grounds are much softer than the mineral abrasive or crushed apricot seed scrubs, and (unlike the latter two) it does not cause skin irritation, at least for me.

I typically wash it to remove tiny particles (so that it does not stain the tub so much) and then soak it in diluted hydrogen peroxide in a refrigerator until I need it.

One thing you could reuse coffee grinds is as a roach deterrent, Roaches hate coffee grinds and if you take your coffee grinds and place them in areas you see roaches congregate..they will find another place, It even can get rid of them all together. Reason I know this is I am anti pesticide and herbicide. There are so many natural alternatives to bug spray..and coffee grinds is one of them !! I think re-brewing coffee grinds is not a good idea, as the coffee produced will be of very poor quality

A friend flushed them in the sink, he said that it cleans the pipes. But then I don't really know if it's true except his sink never got stuck. But that's not a proof!
