Pros: eco-friendly, 100% natural, effective, inexpensive per load of wash
I love these Soap Nuts -- I use them on everything from smelly gym socks to more delicate nightgowns. Each package comes with a small cloth bag in which you put about 3 nuts, then just throw the bag in with the laundry. Clothes come out clean and NO TOXINS or PERFUMES! A family size box gave me about 55 loads. For stain removing power I sometimes add Meyer's Oxygen powder, too, but for most laundry loads all you need are the soap nuts.
Also you can get a trial size for $2.99. All on eZoetic.com.
