There is definitely no alcohol in brake fluid.
Brake fluid attacks rubber compounds in plastic -- many models use ABS plastic resins (the AB is for these compounds) and can be damaged by brake fluid.
Brake fluid cleans up with dry gas or windshield washer fluid. Maybe that's why you thought it contains alcohol?
The old P2K models stripped easily with isopropyl alcohol. I don't know about Walther's newer models using the P2K tooling.
