I hope this is the best forum to ask this question on:
Where we live, mould is basically inevitable on anything that we put into storage for more than a few weeks, esp. on sensitive things like shoes. Air-tight containers with as little oxygen as possible (can't call it vacuum... :)) help for clean clothes but it's of course near impossible to get leather to the same level of through-and-through cleanness.
Which led me to wonder: what if instead of storing things under some approximation of vacuum, we store under regular atmospheric pressure but with the air replaced by an inert gas that won't allow anything aerobic to grow? You can get your tyres inflated with nitrogen, so even if I've never seen a workshop where they offer the service I assume that means that it doesn't require industrial or research lab working conditions.
I haven't yet found anything suggesting that there exist consumer grade storage solutions of a kind where you stuff things in a container (rigid or not), connect it to your nitrogen container and "flush out" the air from the box to replace it with the inert gas before sealing it.
Would such a system be conceivable, and would it indeed help with preservation?
