How to get your dirty whites clean again... HOT HOT HOT water, 1 cap of laundry detergent, 1 cup powdered dish washer detergent, 1 cup bleach, 1/2 cup borax. Tell you what, you have to rewash it once to put softener in but it's the whitest you'll ever see your whites. If you omit the bleach it works great to get stains out of colors too (baby spit up is no longer a stain on OLD clothes)
Peroxide is great in the laundry! Here's how to whiten yellow shirt stains: Mix together 1 tbsp Dawn dish washing liquid, 2 tbsp hydrogen peroxide, and 2 tsp baking soda. Apply the mixture to the yellow area and scrub gently. Leave sit for two hours and launder as usual.

Love this refill recipe! I took a small (1 lb) box of Baking Soda, 2 Tablespoons of Dawn Dish soap, 1/4 Cup of water, 1/2 cup of bleach and stirred it together until mixed well. It filled the bottle to the top, and works as well, if not better for about 1/4 the cost!
