What's Best Care for Piano Black Finish Speakers?

Hello- I just got a new pair of speakers in Piano Black finish. They look great. BUT, I know they need SPECIAL care, to prevent SWIRL marks from cleaning. Can anyone give me advice on the type of cloth to use and cleaners and/or polish for them? Thanks.
My wife has a high gloss finish Yamaha piano, and has followed these instructions for many years with great success:
"The best approach is the least aggressive approach."

High Polish Polyester Finishes:
• Everyday maintenance - lightly dampen cloth with water, carefully wipe piano and follow with dry cloth.

• Greasy Fingers & Dirt - lightly dampen cloth with dish water solution, carefully wipe piano and follow with dry cloth.

•Occasionally - use Yamaha’s Extra High Gloss Polish, do not spray near strings.
When cleaning, she first uses a feather duster to remove surface dust (since the dry dust is abrasive). A soft, clean cotton cloth is her cloth of choice, and she always uses straight strokes, not circular motions. For the "dish water solution" she uses a very light solution of of Ivory Liquid dishwashing liquid detergent and water. Applying the Yamaha Extra High Gloss Polish is something she does only once per year or so (this polish leaves very little to no residue).
My sugestion is similar to Rushton's.--Getting rid of the dry dust first---Then Glass Plus is as good as it gets. NO STREAKS.---Spray the soft cotton tee shirt; not the speaker.Turn the rag after doing one side to dry that side---This I find is much better than plain Windex. The tops are the only side where you have to worry about dry dust.You can blow that off with your breath.
I have used this product on my Definitive Piano black gloss caps to Kharma 3.1 speakers to the acrylic platform on my Basis turntable. Polish with "Zymol" which is made for clearcoat car finishes and will not scratch or leave swirl marks and actually removes them leaving the finish smooth to the point where dust does not settle and if it does can easily be removed. Plus it will bring back older finishes to near new and keep new finishes, well new . I put on a couple of coats maybe twice a year, cleaning between wax with a soft dry cloth or with windex for the flat surfaces where dust would settle.
I second George - Glass plus works great on my pioneer elite TV.
Feather duster
I do exactly as discribed in Rushton's Yamaha post. I use a clean cloth dampened with water. I go in straight lines across the surface and I follow with a clean, soft dry towel. If needed, I use a cloth dampened with a slightly soapy solution, then follow with a water dampened cloth, then dry with a clean, soft towel.


And, keep the humidity in the house at 40%, lest the wood crack.....which usually is not covered in the warranty.
The best type of soft cloth will most likely be a flannel one.You can find it in any material store,or do as I did,and cut up your old PJ's.Use a good fabric softener,and you have a great,soft polishing cloth.
Glass Plus and Windex have micro beads in them. That is why they should not be used on acrylic products or lacquer of any kind. This same reason is why you don't use these products on brass. All bright brass products, in general, are covered in lacquer which those products remove starting the tarnishing process. The fine micro beads actually scratch the surface. All auto polishes also have a similar formulation. Only car waxes fill in scratches. This eventually wears off, though, and leaves the scratches showing once again. Rushton has the correct answer to use water only. Most tap waters should not be used though because of the chlorine in the water. This doesn't say alot about the quality of our tap water unfortunately.
here ya go.....Cory Piano Cleaner....how 'pros' clean Steinways.

Cory Piano Cleaner

i just got my Piano Black Von Schweikert VR9SE's and this was recommended to me. there is also some sort of 3M cloth that is avalible at Auto Detailing shops that is ideal for applying Cory.
The cloth to which Mike refers is generically called "microfiber" - very soft, highly absorbant, no lint residue. It's also widely used for cleaning optics. I used microfibre for my glasses, my camera lenses, and my turntable (which has a gloss black gel coating and an air bearing arm which gets a wipe down periodically). Be aware that there are innumerable sources for microfiber cloth today, made from a variety of synthetic fibers for various applications, and some are better than others.
A microfiber cloth and Wizards Mist N Shine works great for me. It's not a wax per se, but a cleaner that removes fingerprints, dust and stuff, does not scratch or make swirl marks, and is anti-static. Does a really nice job.
