Red threadlocker/loctite

[BTR69]

What's the most effective way to clean up threads, both bolts and holes, after removal when threadlocker has been used? I've used different solvents and brushes in the past, but it's been many years since I've dealt with it. I'm curious what's considered easiest or best practice for it now. I expect to reinstall the clutch sometime in the next few days and hope to avoid any potential hiccups. I didn't see evidence of threadlocker being used on the flywheel bolts when I removed them, but also know the folks at Ram say it should be used. I'll be cleaning them regardless, but curious when dealing with threadlocker products.

Thanks.
