Treatment for rubber speaker surrounds?

See that's the problem with all these Mdf speaker enclosures with Dupont Automobile clear-coat finishes. First it starts with waxing, then moving to the trim with the Armor-All. Boy do I ever miss the good ol'e days of particle board with walnut contact paper. ;0)~

Seriously, I wouldn't use anything on the surrounds. Stop worring, & just enjoy your speakers. As the only issues I have heard of are during lack of use when in storage.

I second Audiobugged, use nothing especially not Armor All.

I third (is there such a thing) the motion above. Leave the surrounds alone -- or, dust them with a soft cloth or duster fm tie to time.
