Do OBA's wash out?
Let me first say this place is addicting. Sine being here, I've probably bought more detergents than since I've started doing laundry in college....
So far I've been trying Vaska and other non OBA detergents after thinking that maybe the OBA laden Sears Ultra we've been using may be responsible for some of the fading in certain darks. From reading here it seems this may not be fading of the dye rather than OBA contamination over the years.
Now that I've used Vaska + Oxygen bleach for a round some of our blacks and dark parts in some shirts seem to be coming back. Definitely looking less faded.
Could this be my imagination or do the OBA ingredients wash out?
