See what Eric said. And, sometimes if you're lucky and the stars are lined
up just right, you can avoid scarring the pipe by wrapping it with a damp
cloth and then grabbing it with the wrench. I use a piece of pond liner
(thick rubber) for this, but you're not likely to go looking for a pond
supply store. Got anything similar, like rubber mats that people sometimes
put in the bottom of the kitchen sink to grow mold as a hobby, or an old
rubber bath mat you can cut a piece from?

Or rubber strap wrenches. Cheap and sold a few places.

BTW, I doubt anything is glued on. It's screwed on.

He may be seeing cruddy residue of teflon tape combined with soap, minerals
and who knows what else.
