I don't know what is in it, but there used to be a
spray surface cleaner
called Fantastik you could buy at any grocery store. I wouln't have
believed it if I hadn't seen it, but in grade-school my teacher used it to
remove the paint lines from our concrete basketball court.
From that experience, I wouldn't leave Fantastik to soak very long on
**any** surface you care about......
That was it's main selling point though, and what was
stressed in commercials for it. I've seen people use the military
version of 'Kool-aid' to clean vent screens and such and I used to
use colas, such as Coke and Pepsi, to remove rust from nuts and bolts.
