i just sprayed window cleaner with ammonia on the window from the inside, and taped black plastic bag from outside and parked in the driveway and now im waiting...Am i doing this right? Or any other ways to do it? Thanks

 

You spray the tint with ammonia, and put the plastic bag on the INSIDE of the car, so taht it trapps all the moisture in with the tint. Make sure its bright and sunny outside, its called sweating the tint off. Loosens it up, but good luck.
