I support 'going Green'...however, keep in mind, "Green" product companies are also in it to MAKE MONEY. Many of these things you can MAKE so much cheaper, with what you already have in your home. The investment in time to find them is well worth it.
How To Restore Stained & Yellowed Vintage Linens Put yellowed items in a large pot of water. Add 1/4 cup salt and 1/2 cup baking soda. (Alternatively you can do this same method using an oxygen bleach.) Bring to a boil and turn off the burner. The SECRET to cleaning linens is HOT water. Allow to soak (with occasional stirring) for as long as needed. It’s not uncommon for it to take 2 to 3 days.
ONLY use this and it leaves floor spotless. (Heavy duty floor cleaner recipe: cup white vinegar 1 tablespoon liquid dish soap cup baking soda 2 gallons tap water, very warm.) It leaves everything smelling amazing.
