Phoenix Gold Phorum

Whats the best and safest way to clean the cone and surround of a woofer/speaker. i ask this because my Immortal came a little dusty and I took care of most of it with some air but I now want to clean the cone and the air comp. didnt really do anything and because its a 2-Layer Carbon Fiber / Kevlar Cone its kinda difficult to just wipe it off with a dry rag. I was going to use maybe a multi surface cleaner on a rag to clean it but I wasnt sure if I should use that or rag damped with water.

I have a few subs and speakers that I would like to clean up so a general cleaning tips would be great

I think using a very slightly moist lint-free cloth work well.

I guess that would be the best thing for them , but what about aluminum spun subs? How can you keep them polished? Aluminum polish? or would that be too harsh???
