Removing Loctite from screws

While searching I couldn't find much on what to use to help remove locitite from screws. I tried cleaning up some scope ring screws that had an really excessive amount of purple Loctite 222 on them. I figured they were trashed but gave it a shot anyway. This stuff was really hard as it was on there for about 10 years. Loctite's website suggests methylene chloride to clean up but who knows were that can be found and don't know if it works on old hard adhesive. I tried soaking them in paint thinner and alcohol but that didn't do much to soften it. Tried a can of cyanoacrylate glue remover called "Goof Off". Got it at Lowe's for $4. Soaked the screws for 3-4 hours and to my suprise it softened that old hard loctite up really nice. Used a safety pin and cleaned the threads up pretty easy. Soaked them again and a nylon brush took off all the bits of residue in the threads. Oiled them up and they are like new. The cleaner had no effect on the bluing. It would probably work on the blue Loctite but I assume it would need a longer time to soak. There are probably other liquids that work but this worked well for me.

Thanks from XXIV Corps, RDS, Lruss and 2 others

I always use heat to break down the loc-tite and I use a thread tap to clean out the screw holes.


Thanks from High Hat and Hugh

I like acetone. You can get a small pot of it at any drug store that is used to remove fingernail polish. Drop the screws in there overnight and they ought to clean up pretty good.

I have had good luck using lighter fluid to remove the blue Loctite.

I just let some scope mount screws soak over night in some CLP and they cleaned up nice.

Thanks from Hugh
