Is it possible to clean the sensor on a Point & Shoot?

Sorry,

I cant answer your question,but after having a similar experience with a cheap point,and shoot Camera I was very fond of for Digiscoping,I now have a couple of Golden Rules.
1 Always turn Camera on,with Lens pointing down.

2 Always turn Camera off with Lens pointing down,AFTER,blowing any foreign materials off the Lens area.

My reasoning,is, if anything has settled on the extended lens tube,Hopefully,it wont be drawn inside the Camera,if the Lens is pointed down when retracted.
