Conservation of a bass guitar

Is there a way to protect a bass against deteriorating? My main concern is
rust. and other unwanted stuff on the metal.
I've played bouble bass exclusively for last few months. and can't see
myself playing a bass guitar in the near future.
I have a pretty good bass guitar tho. But it's a Korean J-bass copy. and has
really low resale value. For me. that bass is as worth as a brand new Mexi
Jazz or even better. So. if I sell it for half the price. I'd probably
regret it the next day.

Keep it in a stable environment...even temperature
and humidity. Scatter a few of those little bags of
absorbent silica in the case if you have very variable
humidity. Under your bed is good!

Under your bed in northern Florida. or south Louisiana is bad. Trust me on
this. Not so much the wood and metal. but the case. Nylon and leather turn
to solid fuzzy mold in no time at all. Had stuff to prove it.
