When we re-installed our front window, there was (of course) some squeeze-out of butyl tape residue. I used a small plastic putty knife to remove most of it, but (of course) there's always some that sticks to the fiberglass around the frame.
I went to the hardware store to buy mineral spirits, which I had read would remove the butyl tape residue. But right next to the mineral spirits was a bottle of Goo Gone in a "Surface Safe" version. I figured I'd give that a try โ the Goo Gone had a pump spray applicator, which would make it easier to target the residue. (Mineral spirits have a tendency to drip.) Plus I figured that even if the Goo Gone did not work for this application, I often need to remove sticky gunk from various surfaces around the house and in my shop.
I was pleasantly surprised by the Goo Gone. It did the job well. I sprayed a little bit on each smear of residue and then wiped the area with a rag. The butyl came right off.
I then tried the Goo Gone on some baked-on patches of duct tape adhesive. (Note to self โ do not apply duct tape directly to the skin of the trailer unless it is absolutely necessary to do so. It does not come off cleanly. And don't let the adhesive residue sit there for two weeks baking in the sun.)
The duct tape residue took a lot more elbow grease than the butyl did, but I was still pleased by the results.
The only downside of Goo Gone is that it is pretty expensive on a cost per ounce basis. It's fine for smaller jobs, but I am not sure it would pencil out for a larger job (or for industrial use).
