try a good car wax. They are designed for such things!

I had a piano finish Kharma speaker, they can be easily cleaned, but if they get damaged, the repair is astronomical! Of course they are one of the best looking finishes available.

Rainman,

The best way to remove hairline scratches/swirls on a black piano finish is with some 3M products basically made for the auto industry. I would start with the Imperial Microfinishing Compound and finish with the Foam Polishing Pad Glaze. You can apply these by hand using a very soft cotton cloth and some muscle or get a orbital polishing machine. Be sure to use a different cloth or pad for each product and work fast. If you still have scratches after that you may want to step down to the Super Duty Rubbing Compound and then work your way back up the the Polishing Glaze. Any supplier to the auto or wood finishing industry will carry these products. A coat of Rain Dance car wax after the polishing will help retard further scratching, but nothing will prevent it unless one never dusts/cleans the surface.

Best,

Zymol "HD Cleanse" followed up with Zymol "Vintage" wax.

to apply the HD...use a soft hand polishing pad and to remove use microfiber towels (wal mart has them) that have been washed...and then rinsed MULTIPLE times as the soap will leave a haze. Trust me on the multiple rinses.

do a small area at a time and don't let the product dry before removal.

the Vintage wax is just icing on the cake as you really aren't exposing the speakers to the elements that a car is exposed to, but the shine you'll get....ohhhhh yeah.

I may not know stereos like many people on this site...but when it comes to waxing a car...I'm OCD...and the Dr's I detail for won't go anywhere else if that says anything.

No...I don't sell zymol...but I swear by it...and so do lots of people that show their cars at the Pebble Beach Concours.

Hi guys,

thanks for the reply to the post. With what it takes to maintain the balck piano finish I t would be the walnut finish for me.

Thanks again. This forum is the best.
