It's starting to get warm around here, and with the warmth comes a sticky front door. When the sun heats up our front door it can be pretty hard to open because the paint on the door and jam like to stick together. I take a small amount of car wax and put it on the jam and on the edge of the door. This keeps the door from sticking to the jam and it opens much easier. The wax needs to be reapplied about every 30 days depending on how much we use the door.
