go 220,320,500,1000 abralon in order and it should come back to life, or even the sanding discs for cab in same grits work well. I have both but like the abralon look much better than the sanding discs for me use lots of water through your abralon pads and you will be good to go.
Ps the good part about worn out abralon pads is you get finer grits that are not available as they wear out more, i have a nice wore out 1000 pad that is pretty close 1500 now. The 4000 pad is pretty worthless but shines a ball without any polish on the ball, one of my favorite trick is high speed on a spinner with 2000 abralon lots of water and stand on the ball. It burns it nicely and you have no polish on the ball at all, clears the heads booms turn on the backend hard.
