Best way to clean speakers

What material are the drivers cones made of?
What are the surrounds made of?
These two will make the descion on how to and what to use easier.
Cheers

Swifter Duster is impregnated with chemicals, and is oily. I would not use it on a speaker cone.

Driver cones are magnesium , tweeter is aluminum alloy , it dose not look like it , it's black , tweeters have been modified . I'm not sure about surround material . I wonder if epoxy like that used with Vandersteens could be added , I can always find one or two loose bolts . I don't think i'll give the elbow grease a try , not even sure where to buy elbow grease . Soft brush on a vacuum cleaner makes sense . The swifters we use around the house seem to have a type of oil or something on them , likely to help pickup dust , i doubt it's good for driver cones or surrounds . I also use cans of compressed air to clean nooks and crannies , but it seems to have a lot of moisture with it . Regards Tim

Gravity does wonders. It's automatic and free.

The cans of air your using wont eject moisture if you don't shake it around to much. Keep the can upright and use the small straw-like thingy to angle up, down, sideways.
