Removing Old Thread Locker.?

heat!

 

Chloroethylene based brake cleaner should dissolve it.

 

Heat +1.
Then thread chaser for nut/female and wire brush for bolt thread to clean before reinserting with new thread lock.

 

Tap for holes, die for bolts

 

Doesn't acetone soften it up/dissolve it?

 

Hot, hot heat...

 

personally , i just add a drop or two of new thread lock and put it back in ,but i am sure you must have a reason for wanting to clean it off ?

 

Heat or “plus gas” if trying to loosen.
If removing from threads then brake or carb cleaner and wire brush.
