Coffee grounds in the garbage disposal

[snopes]

Comment: I have heard that coffee grounds are good for a garbage disposal
as they freshen and sharpen the blades of the disposal. Is this true?

They just clog ours. I put ice and citrus in the disposal sometimes to freshen it up, but have never had a problem with the sharpness of the blades. However, a quick google search advised just that (ice and citrus) to sharpen the blades as well:

I wouldn't put them in the garbage disposal, but they're great on compost piles.

I used to put them in the garbage disposal until I saw a PSA from the local utility saying not to. They didn't say why, but I would assume they must be bad for the sewer pipes or something. I've got a compost pile now anyway, so that's where they go now.

Its because the only think worse than aligators in the sewer is aligators jazzed up on cafeine in the sewer.

I'm pretty sure coffee grounds are not good for plumbing because of the oil they contain.

Good one, Beach!
