Clean Sliding Patio Door Tracks

If your sliding glass patio doors aren't gliding as easily as they used to, start with a bucket of soapy water and a rag. Clean as much of the debris out of the patio door tracks as you can, then wipe them dry with a dry rag. Wait until the next day (to make sure the tracks are dry) and then spray the insides of the tracks with WD40. Slide the doors back and forth a few times to make sure the tracks get well lubricated.
