How do I remove silicone caulking from plexiglass window?

Question

Caulking is in patches of very thin layer. Razor blade did it only for the thick parts. Being softer material the razor blade cannot be used as aggressively as with glass. I'm looking for more like a chemical that might do it.

Answer 1

I had a thin layer (streaks) of caulk on a plexiglass garage window that came off with Bestine rubber cement thinner. worked great.
