Key word: Sealed /enclosed compartment silica gel /desiccant
To avoid moisture and fungus, we all know that we need to add silica gel or desiccant.
BUT, do we do it correctly??
A lot of people use a lot silica gel packs and jammed them into the camera carry case, thinking the more silica gel, the better, right?----Wrong!
When using the silica gel/desiccant, the most important thing is to make sure you store the lense or camera into an enclosed/sealed compartment together with the silica gel.
For desiccant /silica gel, it is a "local" climate control--it can only control the humidity of a very limited space, thus, to create such a space for desiccant to do its job and maximize its performance is imperative. This limited space is the enclosed/sealed compartment, plastic bag or a small box.
Try to place your lense or camera into the compartment with sufficient silica gel right after the use of the camera .
Sealed /enclosed compartment without silica gel has potential risks of growing fungus.
You can choose different size of silica gel to fit into the compartment or even a heavy duty self-sealed plastic bag.
Check the status of the silica gel regularily and alway have a unactivated silica gel pack standing by just in case.
Sauturated silica gel can be regenerated via oven baking
