I also tried the grocery bag idea (got from Arlene) this year. It is certainly no worse that several other methods I have tried and was much less work and less expensive. I think I should have brought a spray bottle downstairs when I did my bag check a day or so ago. But I just don't have the umph to go down there again. I am not unhappy with the results thus far. I think the ones I did lose were probably going to be goners no matter what I did. And I am really impressed with the clumps. I did wash knock a lot of dirt off of them before bagging. Maybe I should have just left the dirt on.
