Remove Sliding Glass Shower Doors

Sliding shower doors are a great improvement over a curtain, but what if you need to remove them for cleaning?

Steps

Look at the bottom track. It is an extruded aluminum rail. The edge that is inside of the shower is probably shorter than the outside edge of the track.
Look at the top track. The top of the door should have wheels that ride against the top shower rail.
Stand inside the shower.
Grasp the near door with both hands and lift the door. The bottom of the door will lift high enough to clear the inside edge of the track.
Lean the bottom of the door towards you as the top of the door remains in the top track.
Lower the door to clear the top track. You have removed the door.
