Oh, and my stain remover of choice....Felz Naptha soap. It's a bar soap you can buy on the laundry aisle. It's about a buck a bar (so it's cheap) and it will remove even the toughest of stains. (When my boys slide into home in this Georgia red clay - I ain't worried!)
It's easy to use, too. Just use hot water, rub the soap on the clothes, let sit for about 5 minutes, and the dirt rinses right out! Snap!
