Default newb ?? - How do you remove old thread locker...

I'm sure this sounds like a dumb question but, I haven't worked with lock-tite before.

I'm wondering what you guys use to clean old gunk off threads before re-installing the fastner?

Thanks in advance for any and all suggestions.

Thanks,
Jason

One of those small wire brushes works for me.

i usually spray it down with solvent and wipe it with a rag. The new threadlocker you put on will work just the same over old stuff as it will on a clean surface.

You should always remove the old lock tite first as this will 'clog' the threads and add resistance that will result in an incorrect torque value.
Thread chaser ,tap and die, wire wheel (not do not use steel wire wheel on stainless Steel fasners) all work well. Follwo up with some solvent and a blow dry with compressed air will ensure good bond.

According to the tech rep at a Loc Tite seminar I attended a couple of years ago, it is not necessary to remove the old Loc Tite, especially if you are not mixing two different compounds.
If you only use the recommended amount there won't be much there to clean off anyway. I still can't help myself from not at least knocking off at least the loose stuff with a wire brush before installation. The liquid will provide lubrication during the torque process so that is not a concern.

I've read that loctite acts as its own solvent; If you have threads with dried compound and apply more, the liquid will quickly dissolve the solid.

But then, I read this information on the internet, so it's worth exactly what I paid for it!

OK this is a new one on me. Hows come you don't use a wire wheel on SS fasteners? I am a maniac when it comes to my wire wheels and cleaning parts.

Thanks, Harry
