Re: Cloth diapers and which laundry detergents to use/avoid - a wonderful chart!
The optical brightner issue is a relatively new one that prolly isn't reflected on the charts yet. It's a dye in the blue spectrum that attaches itself to the fibers to make it appear brighter, without necessarily removing the stain. A particular detergent held the patent on it and just let it run out late last year or early this year. Now anyone can use it. So if the bottle says "brightens whites" or something like that right on the front, be leary of the optical brightners.
