Discoloration on back of Martin Logan Quest speakers


I have a pair of 30 year old Quest speakers.  They work great, but the back of the base is covered with a whitish discoloration.  Any ideas how to tidy this up?

Probably dust from the panels being energized. You can clean the panels and other areas without too much work. For areas other than the panels a dish rag with warm water will do it.
