Why are they paper? they should be marine style, non paper, i dont think you can do anything to clean them, but maybe just get new marine type speakers.
paper was the wrong description. Not sure of the type of material they are made out of but they are marine grade Polk Momo's 6 inch riound tower speakers. I will try to get some pics up later
Kevin, I would dilute it. Straight is a tough customer, and I wouldn't want to damage the speakers. Better yet, call a stereo shop and ask them. I use Jon over at Radioactive 909-464-1010. Good luck.
GD.. funny you mention speaker sox. I have had them on for 3 years and was kinda wondering if that was some of the reason I had the residue on the speakers. The Sox keep the cans clean, But do they hold in some of the moisture causing the blackness of the cones?
