I've heard a lot about people using 'bluing' a long time ago. My Grandma owned and operated a small hotel years ago. They used bluing in their laundry. My uncle told a hilarious story about how he was fooling around with a wringing or rolling device they had in the laundry room.

I don't know what it was. Anyway, it had this 'bluing' stuff in it. He was fooling with this thing, and the 'bluing' came spashing out all over the place. That is one of the few times when Grandma really got after him!

"Bluing" is used to offset "yellowing".

It makes the whites whiter.
