Anyone have any ideas on how to get a stubborn decal to come off of my back window? It's one of those college logo stickers. Is there a special kind of scraper that won't scratch the glass? A certain chemical?

Thanks in advance for any help anyone can provide.

Sorry bro, I had a paragraph worth and I can't post it for some reason.
Lil' Evo can help with this if I can't post soon as it's similar to removing tint.

 

They make razor blades with a little handle on them. Works perfect.

 

Get the blades from any auto parts store. Comes with handle and spares. Heat with heat gun. Scrape WD-40 to remove remaining adhesive. Isopropyl alcohol to clean up WD-40.

 

Two tools will get the job done with no trace of the sticker ever being there. First get a straight razor from the hardware store and scrape it off. Then get a cleaner called Googone that's available at most hardware stores or Walmart and use it to scrub off any glue that remains.
