I can't believe nobody's said it yet so here you go....

wtf is wrong with your "friend" is she crazy????

 

+1 ^ and a more primitive approach, orange peel seems to work well. don't know if it'll work for duct tape, but it worked for paint on my driver's seat and it didn't smell to bad either..

 

Why not just use simple rubbing alcohol? Wipe the residue away with a cotton ball and then wipe the seat dry with a paper towel. Regardless, you've probably gotten rid of the issue by now, so that bring me to the question asked earlier: Why in the world did your friend put duct tape on your seat? Prank, joke?

 

Gently rub some peanut butter onto the affected area. Keep rubbing until you can see it come off, apply more and repeat if needed. My brother did an experiment on this and he was able to remove the sticky residue left on a plastic bottle after you remove the sticker/label. If you do it, let me know how it works, i know it works on other sticker residues but idk how it would work on duct tape residue. Couldn't hurt trying anyways.

 

Take a look at Optimum Power Clean. It can be diluted to 3:1 and is perfectly safe on leather (although I wouldnt let it sit there for extended periods)

Spray some on directly, let it dwell for a few seconds then scrub with a brush or terry towel. Come back with some water (spritzed on or using a damp towel) to make sure you get all the remaining stuff off.

Its an all purpose cleaner that is actually paint safe as well so you can use it for a ton of other things too. Very handy to have around.

 

The thought of rubbing peanut better on perforated leather and have it never to come out.....

 

When I read the title of this thread I had envisioned the post to be more like:

Hi guys, how do I remove duct tape residue and blood stain from my seats? I have some left over chloroform, would that work? <3

Hi, guys, your inputs are very helpful. Thank you very much!

by the way, my friend wasn't crazy. It was because some hater from San Francisco:

If you look at the aftermath photos, you will understand why i have duct tape residue on exterior door panel--we had to use duct tape to hold the mirror in place. She helped out too and kept the duct tape on the front seat carpet afterwards. She got a little on her seat when she was handling it. I don't blame her at all, instead, i appreciate her helping spirit.

 

haha ok that makes sense - at first it sounded like she intentionally put duct tape on your seat just for fun.... like Hey, there's duct tape on your seat HA HA!

Also, sorry for your loss (mirror).
