Maintenance before Storage Replicator 5th generation and Mini plus

I have a maker bot replicator 5th generation as well as a Mini plus, and will need to store them away for a few months. Besides usual maintenance, as well as removing the filament, is there anything I should do before putting them away. They will be stored in a dry, moderately temp. environment.

stick them in bin bags to keep out the dust and critters.
I'd probably put some silicon sachets in with them - can't hurt right :-)

Fix the printheads in place - just in case.
