Best thing to do with debadging and not worry about the glue is to get a heat gun or hair dryer to heat up the glue and then quickly take fishing line (a little more taught, it's slightly thicker than floss, and probably won't break) and pull it behind the lettering before the glue cools down.

That's how I would do it. If there's any left over, I would just use various cleaners or a scrubbie that you would use to wash your car. Just be sure once you start to take it off that you continue until all of it's off because the glue will harden and it'll be a lot harder to take off the next time you try.
