I don't know if it makes a difference in my laundry or not, but I put it in. I perfer bleach for the whites and clorox color safe for everything else. I have used a variety to spot treaters, but haven't found one I like.
I do LOVE oxiclean for keeping my stove clean. I soak those pans that are under the burners once a week, and they are sparkley and clean. It can remove the worst burnt on messes.
I bet it does the same thing in the laundry.
