Anyone have luck removing window tint from rear glass with defrost grid?

The PO heavily tinted the side and rear glass. This doesn't work well with my old eyes. I'd like to remove the tint from the rear glass but it has a working defrost grid.

Anyone have luck removing or have ideas?

Thanks

Well they probably make something that might remove it. But what I have read before is to cut a trash bag or the like that fits the window size and tape it tight to the glass around the outside edge. Place a little household ammonia inside the plastic before you tape the last shut. Let it set for some time. It's suppose to make it come loose. Might help to put some nicks in the tint inbetween the defrost traces.

I'm sure others have ideas.

There are also Youtube videos on doing it. Just search.

Thanks. I wonder if that will also loosen the defrost grid.

Some of the web searches seem to indicate it does not hurt the lines. 1 Link added above.

I had a friend that worked for me tinting windows when I owned a stereo shop, we would use the old liner and put it over the glass and park it in the sun for a while
(called sweating the film) but the best and easiest way to remove film is with a steamer...

If you can get one corner up, it may peel off in one sheet. The glue residue can be removed by spraying with cloudy ammonia and dish soap. Spray it on and let it soak. If it doesnt peel off in one sheet, spray with the mixture and put newspaper over it and let it soak, respraying the newspaper until the film looks milky. It should come right off.
