Sorry to be at odds with you on this one, Geoff, but I would STRONGLY
recommend NOT doing this. These cleaner discs are generally of little use in
terms of actually cleaning lenses, and on several occasions, notably with
Panasonic DVD drives, I have seen them cause additional damage, when the
little bristles get caught in the lens suspension wires, and then tear the
top off the optical block.

I've never had that happen. Since live in a very dry, dusty climate, without
the cloud of hydrocarbons that surround most big cities, I don't get
the "sticky goo" type of dirt that you get on the lenses.

A light dusting off by a brush works wonders here.

Cleaning with isopropyl alcohol is a mistake, it makes mud out of the dust
and often leaves a residue. Ammonia based cleaners are illegal here.

I assume that if I lived in places like Philly (where I've lived) and London,
where I've visted, there would be a lot less dust due to the humidity
and a lot more "goo" due to the hydrocarbon cloud.

However, I've cleaned hundreds of CD-ROM drives and DVD players with them,
but have never come across one that was damaged by fibers breaking off.

YMMV.

Geoff.
