Hi! A thorough cleaning of my folders, including full/partial disassembly, is something I do maybe three times/year, let’s say as “planned maintenance”. Based on circumstances (e.g. working with some particularly “nasty” food prep), I can decide to go for “reactive maintenance”

.
Normally I clean my folders under running warm/hot water, mild soap and a tooth brush or, when really needed, with interdental brushes. Then I blow them dry with compressed air (same I use for my laptop) or, sometimes, with my wife’s hair dryer

. Before storing them away I put a drop of food contact grade oil on the edge and, if disassembled completely, I lube with the same oil (FYI, it’s a WÜRTH product, used in maintenance for food processing industries) the different parts/components.
Taking folders apart it’s fun for me and it’s something I occasionally like to do when I have time and I’m in the right mood. Thinking about doing this always and compulsorily every time I use one might soon become an annoyance

. About hygiene and cleanliness, yes, it’s very important but, as usual, est modus in rebus
