I've been using this "recipe" a lot lately to whiten up and brighten up our clothes. It's great for making the sparkly whiteness come back. With child number four on the way, I've been getting out the onesies and found this to be a great way to remove years-old spit up stains (and other stains!). Even tried it on a few colored clothes and found they did not bleach out.
White Clothes Cleaner
1/4 cup bleach
1 cup Cascade dishwashing detergent
1 gallon hot water
Mix well in plastic tub (I use my dishpan). Soak clothes for 30 minutes then wash the usual way in the washing machine.
