What do you use to keep high gloss speakers clean?

I found a damp chamois to produce less shine but resulted in a more clear and neutral sound while Turtle Wax left a nice and sounded warmer but slowed the music’s pace down significantly.  Never tried Meguiars

I use my cat.

He spends most of the day sleeping, so I thought he should contribute something to our relationship.

He is a domestic short hair (tuxedo cat), but I don't think it matters.

Pledge and a microfiber cloth. Money 

I don't use wax/polish or cleaners, as my speakers are kept indoors and are not exposed to the outside elements like a car.

LOL!

There are also some very good ceramic automotive products out there that, if applied when the speakers are new, should last the lifetime of the speakers if kept inside, and will create a hard, shiny barrier against scratches and swirls. As always, test the product in an inconspicuous area.
