Get a can of compressed air and a swifter use both with care. Anti static wipes are also a good choice. Good luck!
How to go about cleaning my speakers?
I own B&W 805S's and always have the grilles off. I've owned them for about 8 months, and haven't cleaned the actual drivers, just the cabinents and the tweeter with the supplied cleaning cloth. Do I need to clean the drivers? If so, what is the safest way to do it?
