Dust sticking depends on where you live . I dont see as much dust on a
DVD lens but i have seen it . The climate is usualy very dry here and
dusty . Dust sticks to the sides if furniture etc. far worse than i saw
when i lived in a damper overall climate .
If someone has a dirty house with carpet and dogs or kids the dust is
un-controlable inside electronics here not to mention smokers film ,
poor cooking or fireplace or oil heat ventilation .
Here i have fixed several dvd by cleaning the lens . This inclused PS2
units which kids mostly keep on or near the floor that suck in all the
dirt .
