extending DVD & CD Life Span

In the local second hand shops, the owners will spray "Pledge" or
some kind or aerosol wax onto a disk to mask defects and allow it to play
more smoothly. Obviously, it can't rectify skips, but it helps with disks
which are so badly scratched that they just stop in the player.
Currently we have a $100 CD set ruined because of bad scratching.
Does anyone know if this practice works? Could it be bad for the machine
which plays it?
