You disassemble, you wipe it off the coil carefully with tissue paper, and then with harder paper you run inside and around the circular gap until no brownish residue is left to clear.

Thermal intake goes lower, main resonance gets higher Q. Some say the tweeter starts and stops on a dime without the fluid friction. If you use it with a strong amplifier better leave it as is. Crossover needs changes aswell because Z changes around resonance.
