Problem with black finish - ML Quest Z speakers


Hi all, I am new to this board so pardon me if this has been asked before.

The rubberised black matt finish on my ML Quest speakers seems to have "melted" perhaps because of the humidity or temperature. When I touch it, it feels sticky and comes off black on the hands. Has this happened to anyone else before? How do I remove it or clean it? I have tried window cleaner with some success but the finger prints and hand prints are clearly visible. thanks.

I too have had problems with 5 of the 8 pair of martin logans over 16 years I was into M/L.Cosmetic problems, pannel problems ,dammaged drivers,power supplys that would no turn off ,Missing parts,more. These where all in new speakers .I truely think martin logan needs to spend more time on quality control.
