for the sides peel off the tint n then use windex n a razor blade to scrape all the glue off ,as for the rear either pull it off n clean like mad with scouring pad n windex or oven cleaner ,another way is to use a steamer ,another way is the amonia on the tint then cover with a trash bag n leave in the sun ,either way it takes much elbow grease n windex to get the glue n shit off
