OK so let me get this straight- Steam removing window tint?

You open the door with the windows up, spray 100% ammonia onto window, cover in trash bag and seal with painters tap, and let sit for how long in hot sun?

No special tools or talent are necessary to remove old window film. All you need are a few common items and a sunny day.

This applies to all tinted windows, particularly ones that have defroster lines, which can be damaged by razor blades. As such, heat and chemicals are the best ways to proceed on this type of glass. This rear-windshield job took about an hour and a half.
Methodology

Old tint can be removed with fairly common items, including black rubbish bags, Isopropyl Alcohol, steel wool and a razor blade or knife.
Spray the window's exterior with soapy water, cover it with a black trash bag, smooth the plastic flat, and then trim the bag to fit the glass. This will absorb heat, which makes the film expand so that both layers will peel off together.
Inside, protect any close-by upholstered surfaces, and then spray the window film with undiluted Isopropyl Alcohol, ensure that the spray reaches all the way to the edge.
Trap the Isopropyl Alcohol against the tint with another trash bag or, for small windows, plastic wrap. Then let the window bake in the sun for about an hour to soften the tint's adhesive.
Lift a corner of the film with a fingernail or, failing that, a razor blade. Be careful not to nick the defroster lines. The film should peel off in whole pieces; keep the tint moist with ammonia as you strip. Use a razor blade to scrape off any tint that didn't peel.
Remove glue residue with 3M General Purpose Adhesive Cleaner (PN 08984) and 0000 (Super Fine) steel wool, wiping with paper towel as you go
Finish by removing the exterior trash bag and cleaning both sides of the window with glass cleaner.

I've removed this stuff several times and the best way I've found is to grab a corner and pull it off very, very, very slowly. If you go fast, it leaves the adhesive on the window, but if you go slow, the glue with roll off with the tint, leaving a pretty clean window left.

For removing adhesive, use razor blade and Goof Off (not Goo Gone) worked best for me.
