Lens Cleaner

[C0ffin D0dger]

My Panasonic all in one Blu-Ray system has started getting a bit temperamental about reading BR discs. I suspect it's due to dust as we have no shortage of the stuff in our house.

Can anyone recommend a lens cleaner that will hopefully bring it back to life rather than screw it up further. Few options but the all seem to be some variety or another or a disc with small brushes poking out of it.

Thanks.
