Best products and process to polish piano black KEF speakers

Scratch-X works for for superficial scratches and smudges. I tried it for the first time today on my Rel subs. It took a while but it worked.. 

I'm not sure what you mean by 'piano finish'.  Ask Kef what they recommend. I can tell you that many suggestions I read are just plain wrong.  I have a pair of speakers finished in Steinway black, which is a satin finish with a nitrocellulose lacquer paint. like a Steinway.  A dampened rag with water is all I ever use and is the recommended method from Steinway.  I grew up in a home with one and had the same finish done to my speakers.  The latest models might be using polyester paints, not sure though.  Don't use polish or car products.  

@vitussl101 If you look at the finish for KEF speakers they are high gloss hard finish similar to a so called Steinway piano in black.

however, they are showing light scratches and no microfiber cloth with water will polish that away. I’m not saying they are deep scratches, rather we commonly refer to as swirls on car paint surface. I went through today and was able to reduce some of the scratches using suggestions, not car polish! I will see if I can post the before and after once I am satisfied with the results.

I ended up trying 

@rayray57 I just looked at the photo of your KEF speaker, and the finish looks like it has some indentations in the finish besides the scratches.  Did you ever reach out to KEF about suggestions on how to approach improving its appearance?   Typically, piano finishes are quite hard and don't mar that way.  If you're going to experiment, maybe do it on the bottom of the speaker.  Good luck.

   On another note,  I see that you use custom-made DigitalDeckCovers.  I have had many made for my equipment in different colors, materials, and liners.
