Of course, somehow you need some "magic" in the stuff ;-)
But as you might have seen, the weight in weight is 10% maximum. And when
sprayed on the surface (only a small spot) it generates a nice solid foam.
It hasn't dissolved the binder/oxide for now, not even on Wabash floppies
(that in my experience aren't too horrible, some noname stuff is much
worse).
If I'm afraid that it might dissolve the media I can always test it
first on the inner side next to the hub hole. And I don't rub the
media with high pressure, only gently. It is important to extract the
floppy from its sleeve for cleaning, though.

I use Screen 99 for cleaning floppies
