Desicant can

[Grute Man]

I have a desicant can for my gun safe.  It's got the little beads inside a can which is completely preforated.  The direections said to bake it at 250 degrees for an hour and the beads are supposed to turn blue.  Well not even 10% turned blue.  I turned it up and tried it for a bit more but nothing was getting blue that wasn't already starting to turn blue.

Do I need a new can?  Should I turn it up more?  Does it need more time??   
Thanks y'all

I have heard mixed reviews on the can systems for safes.  I got a "Golden Rod" last year from Santa.  You plug it in and it heats up, keeping the inside of the safe warm. It doesn't blow warm air, just keeps an even temp year round.  I have yet to have ANY rust or imperfections show up on any gun since I put it in.  Costs pennies to run too.

The only way to go

If you want a cheap way to go try using a low watt light bulb like a appliance bulb.  It should give off just enough heat to get rid of moisture plus you can see what is in the safe.
