Re: Removing dried duct tape residue from paint

quote jpatti75:

I’d be careful with ammonia … I know it will eat at lacquer paint. Not sure about enamel. Goo Be Gone or other kinds of orange cleaners are usually good with that stuff.

If you have strong ammonia (stronger than you can get in stores) and you leave it on for a mild amount of time it can break down paint. The stuff you can get in stores, especially if you dillute it with soapy water, won’t hurt the paint unless you soak the parts in it overnight.
I’ve used it to remove old fuel and grease on multiple motors, most successfully with my ’57 Fleetwin.
