Heat is what breaks the bound on loctite! If you go to there site you will see this is how they recommend to break the bound. I all so mostly use purple Loctite as it is made for small fasteners and is much easier to take apart. If you have really good servos they should be moister resistant and I rarely take mine out when cleaning unless I am doing a major clean up and service. Now I do not recommend submerging or socking. I use either Wild Cat extreme cleaner or denatured alcohol.

This is what I use to heat up screws with loctite on them.
