If you have shower doors in your bathroom, you're well aware of the dirt, soap scum and mildew that can hide on the track beneath the doors. While you can slide the doors from side to side to clean the track, it's nearly impossible to reach the entirety of it. Removing the shower doors for cleaning is not too complicated; it only takes a couple of minutes.
Check the shower doors for a security brace and unscrew it. Typically, this is a bracket at the inside bottom of one door that stops the door from sliding. Not all shower doors will have this feature.
Open both doors so they are centred in the opening.
Grasp each side of the outer door, placing one hand at the centre of each side edge.
Lift the door upwards one half inch, and tilt the top of the door outward (toward your head). This will disengage the rollers that hang on the upper rail.
Lower the outside door slightly to clear the upper rail and lift the door away from the tub area.
Repeat the process with the inner door, but tilt the top edge inward toward the back wall of the tub. Lower and set aside as before.
Before beginning, decide where to place the shower doors once they've been removed. Shower doors are typically made of tempered glass. Because of their bulky size, place them in a secure area where there is no chance they will slip and break.
