I've been brewing with cheesecloth to great success. However cleaning this this is kind of a nightmare. The best solution I've found is putting it in the washing machine, however I wouldn't put it in with anything else. I had grain bits in my pants pocket for a week after I washed my jeans in the same load. Any other ideas for cleaning your bag? The other draw back of the washing machine is how long it takes, so if you wanted to do back to back brews you'd need more than one bag.
