[Histonet] Removing hematoxylin from clothing

I keep a little bottle of acid alcohol on the shelf above the washer.
Stronger than you would usually use on slides, 4% to 5% HCl in 70% ethanol.
I pour a litttle on the hematoxylin spot, rub it in a bit, let it sit a
minute or so, then drop it into the already running washer.  Works well on
other basic dyes too, like safranin, basic fuchsin, etc.  Of course on white
clothing, bleach will remove many such dyes.  But I use the acid alcohol on
colored clothing that I don't want to bleach, and I usually use it on whites
too, just as added insurance.
