I'm also trying to stabilize the refrigerator I will use this summer to store my coolidors. When not actively running, the humidity tends to climb higher then I think is safe. I found some Silica Gel re-chargeable desiccant beads at Hobby Lobby for $15. There is an online coupon for 40% off today. 5 lbs of beads cost me $9 no smell. I'm testing them now.
