I remember 1 thing from a short photography class I took in high school. If you ever get sand in your camera you will not get it out. We took our camera to the beach and were not very careful to keep the sand away and guess what - it's dead now. By some miracle it died right after I photographed my last piece of jewelry for yesterday's giveaway and restocking the shop.
Since I knew my camera was ruined, I decided to try taking it apart to see if I could get into the lens (the sand got into the lens somehow and it wouldn't zoom right or focus). Guess what - I couldn't fix it. A new camera is already on it's way, but I'm still sad. I LOVE that little camera.
