What's the best speaker polisher/cleaner

I agree with Gs5556. In my case, I use a different material. It's a cloth made by 3M that works by the principles of statics. It will pickup the dust, but will not damage the surface. For more info, go to the Martin Logan website(They're selling it there). You can actually order this from stores(mostly paper or office supplies stores)that carries the 3M brands.

guitar polish. for black my favorite is gibson. it really brings out the deep hughs. guitar polishes are usually the safest because they don't leave a film like standard furniture polishes.

Hrley Davidson makes a product called Harley Gloss "Quick Detailer" No abrasives. Goes on easy wipes off easy and SHINES!!!!!!!!

thanks for your comments guys.I like the mirofiber towel idea. However, will my speaker crack over time if I don't use any polish? I live in Colorado, and it's very dry here.
