do you have any uses for used coffee grounds?

Just throw it in the sink! Why? Because the coffee grounds help to get rid of fat residues in the plumbing. (like the scrubbing in cosmetics, mentioned before)

My mother always dumped coffee grounds on the ferns around her Maine cottage. The ferns were lush and thriving.

I got this Odd tip in an old magasin and it works with a french press

I either use them on my garden or toss them on the trash. I have always avoided putting coffee grounds in my garbage disposal because I was advised not to years ago. Here's what I found today on a plumbing website:
Avoid putting coffee grounds down the garbage disposal. They won’t harm the garbage disposal and they’ll actually help eliminate odors. However, they can accumulate in drains and pipes, causing clogs. Best to avoid.

Ever so often, my counter tops get sticky even though I give them a good cleaning daily. When that happens. I sprinkle used coffee grounds on the counter and scrub away. It is a gentle way to remove sticky stuff.

They're excellent in compost.

They're excellent in compost piles and worm bins- Pete's coffee stores give away large bags of exhausted grounds for this purpose. I use unbleached filters, and throw the whole thing in. They're also said to discourage snails, I think, but I haven't seen it myself. There's a hydrangea outside my kitchen door that more or less grew up on coffee grounds, and it didn't seem to keep the slugs away, at any rate.

Here's an interesting piece on using coffee grounds in your garden: http://www.gardensalive.com/product/using-coffee-grounds-correctly/you_bet_your_garden Be sure to link through to the whole article. Very informative! ;o) P.S. Occasionally I put them, in small quantities and scratched well into the soil, around my blueberry bushes and Meyer lemon. ;o)

I use it instead of baking soda in the fridge for air freshener - works like a charm. I've also heard it works as an ingredient in homemade body scrubs (like salt or sugar) but I haven't tried it myself - but Old Man Google can probably gin up some recipes for you!

I use them to make a DIY disposal freshener. It also sharpens the blades. It has coffee, baking soda, salt..I forget what else, but I can get the link for you if you'd like.
