How to loosen a stuck ball joint on an articulating arm

I use an articulating arm like this Smallrig one to mount some random accessories to my laptop station when I’m out in the field at work. But lately both of the ball joints have gotten a bit “sticky” due to the ocean breeze and water occasionally coming into contact with the joints. Short of buying a new arm which isn’t that expensive, I wanted to see if lock lube or metal lubricant would work to loosen the ball joint without losing the ability to later have the ball joint lock precisely in place.

Well, good news. The lock lube works! I picked up a small spray bottle of lock lube metal lubricant and sprayed the tiniest amount into the metal ball joints of my articulating arm and it instantly loosened it up when unlocked. It was like new! And more importantly, when I lock the articulating arm, the lube does not make the ball joint slip at all.
