LocTite Solvent?

I'm trying to remove old, dried-up LocTite from some scope mounting screws. I've tried acetone and rubbing alcohol, with no luck. Any ideas what will cut/desolve the dried-up LocTite? Thanks is advance, Bill.

The best LocTite solvent is propane and a lighter.

However, running the screw in and out of a threaded hole will help. Or soak them in Acetone.

Thanks, guys, but I didn't ask the question clearly. I've got the screws out; I'm trying to clean them off, and the threaded screw holes out, before I apply new LocTite to reinstall them. Sorry for the confusion. Bill.

I chase the screw holes with a tap. But you can run the screws in and out of the holes to remove what you can. Hit the screws with some acetone and use a "Q" tip and acetone to swab the hole. After that the new LocTite will work just fine. If you need it.

Actually Loctite doesn't "melt" is decomposes at 400F

Though some of the high strength bearing retaining compunds will hold on to 450-475.

I'll second (or fourth or fifth) the recommendation for a propane torch.

Sounds about right! I just removed my LocTited on muzzle break. I thought the stuff was supposed to decompose at lower temps. I'll be machining off the next one!

While you bicker over the word melt

Loctite makes a solvent for removal of the residue. It is composed mostly of nitromethane.

Hoppes #9 used to contain nitromethane. I don;t know if it still does but it cleans my Loctite coated screws.

You won't want to be using a propane torch around Nitro-methane, that barreled action will set a new quarter mile world record!

Hoppe's #9 use to contain Benzine. Of course that was back when the stuff smelled good!

Torch and then a dental pick.. My best friends dad is a retired dentist and those things are good for lots of stuff!! Also, after the heat is applied blast with brake cleaner ---that gets most of it..

Later formulations of Hoppes contained Trichloroethane (commonly called "TCE" or "Trike") but that too is gone from the formulation.

Acetone is a "silver bullet" for cyanoacrylate ("super glue"), but loctite isn't cyanoacrylate.

and nobody here is "bickering" and if you use that word again don't do so before posting a definition to PROVE you've read the definition.

I was "quibbling" which is NOT the same thing
