I've had my Panasonic Dvd player for a year, and would like to clean it since my house collects dust (must be the insulation since it's a new house built in 1998). i was reading an earlier thread about someone using one of those dvd drive cleaners with the brushes that fixed a problem with their dvd drive not recognizing discs. im probably over-reacting, but im concerned that maybe the brushes on the cleaner disc could possibly scratch the lens, or maybe mess with the alignment of the lens. could that really happen? tia!
