I saw an old topic discussing how to whiten clothes and notice that someone used thier Dad's old bluing soap. They didn't know where to find it. VermontCountrystore.com has a lot of the oldies but goodies and I have found it there. It is located in the Home section under Laundry. It is called Mrs. Stewarts Bluing and costs 9.90 for 2 z. bottles. I just orderd some so I will let you all know how it works.
