Advertisements I've been using a clamshell style DVD cleaner for a good while now. Bought it at Radio Shack, and it came with a bottle of cleaning fluid. I found that another RS product sold as A/V head cleaning fluid was apparently the same stuff, so I've been buying that ever since the original bottle ran out. Now, it looks like RS doesn't sell either the clamshell "machine" or the A/V head cleaning fluid any more. Anyone know a source I can go to for more disc cleaning fluid? Again, this is for the DVDs themselves, not for cleaning the lens on the machine. Help?
