What is an easy way to remove old hardened pipe dope from black pipe threads so that I can install new fittings? A wire brush is not working very well. I have some solvents around the house I could try?
Thanks,
Todd

The best tool for straight, splinter-free cuts is made even better without a cord.

If it's hardened, how about a wire wheel on an angle grinder?
Dont pay it any attention. I doubt there is any left where the threads were used . If it is it will break loose easily.

Propane torch. Warm it and then wire brush it. It will clean up like new. DanT
I considered using a heat gun, but I want to be safe. The pipe is part of the house system, which will be shut off and permitted to vent for 15 minutes or so, but I am still weary of using an open flame.

I just gently chase the threads with a die. It'll clean up little nicks and burrs in addition to the hardened gunk.

Angle grinder? A bigger mess than I was hoping for.Leave it alone? I like it, anyone concur?Torch? Maybe on a bench top, but I am weary about using it on a pipe that is already a part of the system.Die? Don't have one, and I don't think I could turn one in the limited space that it is currently installed.

No die? no biggie
Use a coupling to chase the threads.
Personally I just leave it on there & put more on when joining the to pieces.
All pipe dope is, is a lubricant so the tapered threads don't bind when tightening.No Veterans = No USA-----Bumper Sticker
Dies are 2" square for 1" and under NPT. Turning by hand is all it takes.
