Default Rusted in grub screw.

I had two small knobs both with rusted in grub screws, I filled the hole that the shaft fits into with wd 40 left it for an hour or so ,applied heat to the screw with my soldering iron tip , inserted a good fitting screw driver, managed to to turn it a little then with a rocking motion whilst giving it a squirt of wd got it free, this worked well on both knobs , Mick.
