I finished typing about this in another thread. You might be surprised by how much good the steaming will do - I was! Just be patient - do a few "treatments," rewetting your cloth each time. When I was researching my own repair, my search of TB indicated if steam doesn't get you there, CA glue and sandpaper was probably the next step. In my case, steam was all it took.
Can't say I know what CA glue is, though.
