Best home remedy for paper cone woofers cleaning the dust off?

I might wipe them every once in a while with a clean sponge, barely damp with water. No cleaner. No conditioner. Won't do any good. The ozone that is responsible for most of the degradation of rubber or foam is generated inside the cabinet by the electric field of the voice coil. It ain't much. But it has nowhere to go. 

If you're really into it though you would use a nice brush and vacuum. Griot's Garage probably sells a whole kit for this. Lol!

Agree to ’let sleeping dogs lie’ in the rubber-surround dept (unless perhaps you are in the desert and there’s never any humidity) and second the idea of a gentle vacuum brush. I understand the rationale for paper cones but they can definitely be fragile in use.

I use a simple soft dust wand to clean my speakers so no damage easy on the surfaces and takes the dust off. just don't press too hard. If you do it regularly there is no need to cleaners or water. The car cleaning industry has many very good dusting ideas to consider as they are designed to not scratch the painted surfaces of a car.
