Bunch,
I decided to apply a little knowledge of chemistry and found the
solution.
The green stuff is a metal oxide, so we need some sort of reducing
agent. In the US, at least, there is a product called "Lime Away",
which is used to remove water deposits and rust from sinks and
plumbing fixtures--its active ingredient is dilute phosphoric acid.
In theory, this should do the trick.
In practice, it indeed does work.
I squirted some of this onto one of the shirts, plus some of the
concentrated laundry stain product Shout (though you could probably
use anything similar or just some liquid detergent) to remove any
residual grease, and everything was fine this morning. Note that it
doesn't remove the stain immediately--you need to let it soak for a
while.
Note that your mileage may vary depending on what you are using as
your slide grease. That is to say, the Lime Away will take care of
the metal oxide, but you may also need a good grease remover.
A better life through chemistry!
Regards,
Carlisle

Hornfolk,
I played a couple of concerts a while ago where the concert attire
was the usual white shirt and black pants.
I hadn't cleaned my horn for a while, so the slides were a bit,
well, messy. You know, that little bit of black gunk on the
slides, the combination of slide grease and a little bit of metal
oxide. I managed to get that on onto shirts I was wearing.
The question is: How do you get rid of the stain that stuff leaves?
Thanks,
Carlisle
