Charlie's Laundry Powder
Charlie's Laundry Powder is a revolutionary approach to laundry care. It does not cover up stains and odors with scents and brighteners - it really cleans. It is made with a unique blend of biodegradable coconut-based detergents and high-grade, completely soluble, Green River washing soda. Front Loader/ HE compatible.

Directions

(For First Time Users) Run an empty load (or perhaps some old rags) with the recommended amount of Charlie's Soap Laundry Liquid or Powder.
This will clear your washing machine of any residue left by previously used detergents and keep them from redepositing on your clothes.
