maybe WD-40 and a heat source should be recommended with an abundance of caution. (and a heap of common sense).SMF said: I would think a wd-40 soaking, followed by a heat gun, followed by the razor blade is the hot ticket.
WD-40® aerosol is considered flammable for other reasons beyond flashpoint.
WD-40® does not have flashback, but can carry a flame forward, so it is categorized as flammable.
