Another baking soda fan here. You can get a big bag of the stuff in the laundry aisle at the store. It has a scoop in it, and directions for using with laundry. I got a 5 or 8 pound bag of the stuff for just a few bucks. I may have got it at Sams Club?? I don't really remember, since the bag has lasted me 2 seasons so far, and I wash my clothes in it about weekly. Depends on how many times I go out.
