Maintaince of our gear is really important, before, during, and AFTER our adventures! Most do the first two but it’s that last one, after, that seems to get pushed aside in the excitement of being home with our new images. My normal process is to clean all my gear before I board the plane to come home. Then once home all the gear is pulled out of the bags (inside to the bag gets vacuumed out) and laid out to come to room temp for 24hrs. Once that is done, I go through a deep and thorough cleaning which includes pulling off filters and getting all glass surfaces. Qtips in all the nooks and crevices around the camera prism and lens switches. I even go through the battery compartment. I’m talking thoroughly here right down to charging all batteries and cleaning lens/body caps. I even make sure the clock in the camera is set back to my time zone. This ensures my gear is ready to go on the next adventure, any booboos and repairs are dealt with, and nothing is missed. Knock on wood but doing this, I have never had an issue in the field where my gear left me unable to shoot. It’s a simple thing but important, that after adventure clean.
