"Cleaning clings Dust as needed. Use a cloth to clean over and around clings with a little water or windex. Do not soak in water. Removing clings Lift edge with fingernail, carfully working off from all sides. Avoid stretching of folding. A spritz of water or windex can be used to renew the flexibility to old clings that feel stiff. Humid days will make the clings more flexible also. On hot days, move clings when its cooler. In cold weather clings become stiff from the cold window, and need to be warmed a few seconds with a blow dryer to assure flexibility before removing."
