Any abrasive will remove the polished layer.
Most times it's safest to sand with the grit level of the underlying grit level, unless you used an abrasive which will have changed the underlying base.
If it was 600 grit + polish, sand with a 600 grit sandpaper or a green nylon pad.
If it was 2000 grit Abralon + polish, sand with a 2000 grit abralon pad.
If it was 4000 grit Abralon .... etc.
