Hi there,
I have a small problem. I was cleaning my SVS sub the other day because it was really dusty and I used a damp cloth. I notice now that I have three circle marks but I don't know if it was because I used a damp cloth or not. Perhaps it was raining and the window was slightly open. I don't know.
But it is noticeable.

Zoom in a bit and increase the brightness to see the three circle marks on the surface.
I tried cleaning it but they won't come out. If I try to clean it with a damp cloth or with cleaning solution, it looks fine, no marks whatsoever, but then as soon as it dries up, those three marks are still there.
Funny, those marks werent' there a few days ago which makes me worried how they got there in the first place. I am quite critical of these things.

So now this is bugging me to no end.
Please tell me that there is something I can use to rid these circle marks from the sub. There has to be something.
--Sincerely,
