we should have a sticky concerning label removal, most commonly used techniques ect... Maybe it could also include adhesion methods, I learned the milk trick on here, my personal favorite. So, a "labels; an off and on relationship" would be great.
Just for the record
Labels off=Oxo-brite (oxyclean type cleanser made by EFP, Earth Friendly Products)
Labels on=Milk (usually 1% or 2%, 1/2 and 1/2 is hard(er) to get off)
just a suggestion
