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?

If it's any area you are afraid of touching a soft painter's brush will work.

Make sure if it's near panels to de-energize the speakers long before dusting.
