Remove the white felt washer, pour the desiccant into a small homemade aluminum foil pan and bake for about 20 minutes at around 200deg.
I use a toaster oven, a gas oven creates to much moisture. You'll notice they are a lot bluer than when you bought it.
Put your finger over the center post and fill the bowl back up, put the felt washer back, screw the top back on (hand tight) and you're good to go.
