Theres no option for `as often as i feel necessary' . If my mirrors collect dust from a lot traveling I would wash as often as monthly. Many mirrors based around cities and bushy areas have a grease film from pollution and eucalyptus oil that is pretty tenacious, and cause quite a bit of glow around brighter stars. Breathe on the mirror edge and if the breath pattern comes up blotchy then you have grease to remove.
