How do I remove old shower doors?

You take doors of first then get a screw driver in the bottom track there is screws take all screws out on bottom sides then clean

You can lift up the outer shower door and the door should lift high enough that you can tilt the bottom of the door over and out of the bottom track. Then repeat for the inner door The track should have screws that go into the wall on both ends that you can remove. There will also be a silicone seal which you will need to score and remove to remove the track. Then clean/remove any remaining gunk, caulk, etc. from the wall and edge of the tub. Fill the screw holes in the wall with spackle or joint compound, let dry and you can then prime and paint when ready. Good luck.

Take the doors out of the channels. Remove the channels and the side and top supports. Clean it well. If it was caulked with silicone, there is a silicone remover on the market. Check your hardware store.

I had this same problem in the past. I took the doors out of the track as others have suggested. However, I wasn't up for removing the frame and track. Instead, I hung a shower curtain (I opted for a tension rod) above the frame. When the curtain is closed (which is all the time in my house unless someone is getting in or out of the shower) you can't see the door frame.
