My favorite way of dealing with coffee grounds is to use disposable cotton tea bags like these: Amazon.com: 400 Pack Disposable Drawstring Tea Filter Bags Safe & Natural Unbleached Paper Tea Infuser Drawstring Empty Bag for Loose Leaf Tea (Natural Color One Size): Kitchen & Dining
2 of them loosely filled works great for an old percolator pot and makes clean up a snap.
