My shower door is 7 years old. The door was getting stuck when I tried opening it from the inside and noticed that the sweep was warped. It's held in place by three metal screws (screwed into a metal strip). They seem to be hopelessly stuck. I've tried cleaning off the hard water build up and have sprayed the screws with WD-40 and let it sit overnight.
I've tried placing a rubber band between the screw & screwdriver and have tried using a hammer and screwdriver to loosen the screws but they refuse to budge and I'm afraid of stripping the screws. So far I've only used a manual screw driver but it's hard to apply hard pressure when the shower door is still hanging on the hinges. Does anyone have experience with this sort of issue or can offer some good suggestions?
Thanks
