If you are smart enough to know the word "halogen"
then you should be smart enough to know what
chlorine bleach is. There may be some products
with bromine or iodine, but I wouldn't want to use
them on my clothes. And certainly, none have
fluorine in them.
Actually, "Whink" rust stain remover, usually found either in the
laundry aisle or in the bathroom cleaners section, is hydrofluoric
acid in a plastic squeeze bottle. Strong enough concentration to
etch many porcelain fixtures, but it does remove rust stains quite
well. Just avoid those nasty HF burns....
(And people say bleach would be hard on your skin ;-)
I have never seen that product and couldn't
believe it contain HF, so I googled. That is just
unbelievable that a commercial product like that
contains HF.
I can see how you looked for a product that
contains fluorine from my statement. But, my
statement was directed at bleaches and HF is not a
bleach. I would think that any compound
considered a bleach with fluorine in it would be
highly unstable.
Yep HF would get rid of iron stains, by dissolving
it, but excepting some waxes (which HF used to be
shipped in wax bottles) and plastics, it dissolves
just about everything including what the rust
stain was on and you. This HF must be pretty dilute.
