Blue Loctite Removal - Help Please!

Aug 06, 2008 3 Replies

Hello! How do you chemically remove 'Blue Loctite'?



I applied some to the terminals on my VDO dual terminal oil pressure sender to prevent the two round fastener nuts from coming loose.



I broke my other oil pressure sender when I tried to remove the same nuts. They had been overtightened.



I was thinking of using a few drops of carb cleaner to remove the Loctite and/or heat it first with a hot air gun before attempting removal of the round terminal fasteners.



I was thinking of doing this first on a small nut and bolt to see how it works.



TIA Any help is appreciated!


If the heat gun doesn't work, I would try a soldering iron/gun to apply localized heat to the brass nut.

A soldering gun could have the copper heating "loop" trimmed/shaped to fit in the tight space.

Hmmmm Blue Loctite should not be that hard to remove. Chemicals like maybe Acetone (fingernail polish remover) might work but getting it inbetween a stud and nut might require soaking. Yes a soldering gun heating up the nut should help. ;-)

WOW is that Speedy Jim back? One of your first posts that is always helpful! ;-) Welcome back and keep 'em coming!

I've used acetone to clean up blue loctite but it might not penetrate into the threads much.
