Cleaning the drive heads

[Puckdropper <puckdropper(at)yahoo(dot)com>]

Hello all,

I got a bunch of used games from a guy online, and have been working on 
testing them out.  These are old disks that haven't been used in a while, 
so I know a few of them are leaving junk all over the drive head.  When I 
put in a known working disk after using some of the unknown disks it 
doesn't work at all.

Last time cleaning the head fixed this, but I don't want to risk damaging 
the heads by cleaning them too much.  I've only got one drive.

Is there a safe way to clean the heads?  I've got a Unidisk 5 1/4 drive, so 
getting to the heads isn't too difficult, but it's not easy either.
