When you have desiccant packs that have some age or find them sitting on the counter they will have absorbed moisture. Most have a color indicator built in. If it is blue then they are ok but if they are pink they will need to be dried. It is easy to "recharge or dry" them. Place them on a metal cookie sheet or something similar then put them in the over with the temp at 250 degrees. Leave them for a couple of hours or see if they change color back to blue. You may have to leave them in the oven all night to get them dry. This will allow you to use them over and over while saving a lot of money. Good luck
