Soundbar cleaning and maintenance.

Hi everyone. I have a question: how do you clean your soundbars, or what kind of cleaning maintenance do you perform?.

I’ve seen some people recommend Pledge furniture polish spray, while others suggest using only dry cloths.

What do you recommend?

I have a Samsung Q930H soundbar. With this model, the subwoofer is the most exposed to dust and the environment; the casing is the easiest part to clean, but what should I use? The soundbar unit and the satellite speakers would be the trickiest parts.
