Hi all,

I've got a few bags of this silica gel stuff in with my scopes. Some of which is a few years old. I've heard about 'recharging' them by heating, but I'm just not sure how or where to do this. Out in the sun, or a warm oven (<70*), and for how long to dry them out for.

Any one have more of an idea?

Cheers,

Mental.
