I was taking photos of people playing Holi. Some of the powdered colour landed on the lens of my Canon Powershot S95, and in the groove of the flash housing. By lens, I mean the cylindrical part that retracts, not the glass.
Does the housing of the lens have some protection that wipes the lens as it retracts (i.e, a self-cleaning mechanism)? Or will I need to give the camera to a professional repair shop?
