For preservation should I leave minifig hands in torso or remove them for long term storage?

[Mistresspaige7120]

I have a few older figs I’m looking to store away and preserve and was wondering what’s the best method to store them? I’ve disassembled the head, torso and legs but should I also remove the hands too? Or am I doing more harm than good since they arnt supposed to be removed due to how they’re designed. Ie. Like you shouldn’t remove the arms since it can damage figs overtime. 
 

Im assuming leave them in since all torsos are manufactured with them in and really old sealed sets would still have them in the arms of the Minifigs anyway and they’re usually fine.
