Hot and dusty where I live.. Vacuum with a brush attachment. If I see surrounds getting too dry I’ll treat them. I only use Silicone or BR surrounds so silicone is the best treatment on the surround, not the binder (glue). I apply the silicone with a lent free rag. I have 50 year old BR surrounds and 75+ on cloth/wire surrounds. They will last another 75 years.. The suns UV are the killers..
I quit dong the car wash thing.. Every time I let them dry out... :-)
