Is there any solvent/solution to help remove duct tape adhesive?

the right mirror on my car broke off in an unfortunate new year's eve charade and i've been keeping it on with duct tape (sad). unfortunately, i have a bunch of duct tape adhesive that doesn't completely come off with scraping alone.Is there any solvent/solution to help remove duct tape adhesive?
Ilike a product you can get at Wal Mart called oops. Use it in a well ventilated area though because it stinks very badly.Is there any solvent/solution to help remove duct tape adhesive?
Goof Off works great...http://www.valsparglobal.com/val/residen鈥?/a>





or my favorite:





Goo gone http://www.officedepot.com/ddSKU.do?leve鈥?/a>





just spray a little on the tape glue let it sit for a few seconds, best if you gently rub it in with your finger then wipe off. Nice thing it is smells like oranges.
WD 40 is awesome for this job. :-)
First rule is not to damage the paint, so avoild harsh stuff like nail polish remover or alcohol. The best thing to use is an oil. WD40 would work, but it has a lot of silicone, which isn't great for the paint. I'd suggest lemon or orange oil, which are sold as furniture polishes. Work them liberally into the goo until it comes off. Use dishwashing liquid and water to remove the oil residue.
Lighter fluid (naptha) works the best, buy it at Wal-Mart (Ronsonal, Zippo_
agree with everyone who said wd-40 or any kind of lubricating spray can be some cheap off brand one
bug and tar remover





nail polish remover





isipropyl alcahol





if none of that works, I don't know what will.
There's a product called Goo Gone that we used to use at a restaurant I worked at and it works miracles on sticky residue. I'm not sure where you can buy it but my guess would be maybe walmart, Lowes or Home Depot, or maybe a craft store.. or maybe even an automotive store. Just call around and ask, I'm sure you can get it and it's definitely worth it!
goo gone, wonderfull stuff, works great,smells like oranges.(citrus based) wont hurt your paint,or plastic,and ya wont smell like a nasty ol auto painter when yer done.
