Anybody know how to get duct tape off glass windows?

[Chomskyite]

Mine is not coming off my windows at all, leaving scraps and film of hardened adhesive on the window. What can I do?

Seems like the near hundred degree heat (in September and early October!) we've had here in Hammond baked the duct tape onto the glass!

1. A hammer?

The same is true of good old masking tape, or just about any other kind we used back in teh bad old day.

Think razor blade, goo gone and a lot of elbow grease. You can eventually scrape it off with a razor. It's just lots of work.

2. citrasolve

concentrated citrus oil, found possibly in hardware store. It also smells like citrus oil (duh) which is rather nice.

4. Paint thinner (Mineral spirits) work for vinyl tile, sheeting adhesive,

I would think it would work for duct tape adhesive.
