How do I safely clean the LCD screen of my new Canon Powershot A4000 IS camera? It appears that this model does not have an LCD intended for touch such as the A3400 IS. Someone at either the store from which it was purchased, or a factory worker, left a few skin oil fingerprint smudge marks on it. How can I determine if such touching has adversely affected the screen? If there's no reason to fuss with it, and no harm in leaving fingerprints on it, perhaps it would be better to just leave it alone. Then again the presence of such oil might affect any coating on the LCD screen. Also, if I want to purchase some suitable plastic protective film to place over it to prevent future scratches, (I can't see the existence of any scratches as of now), it seems that it might be a good idea to clean it up first. But I could be wrong. I'm a new user, and I looked all over the place for guidance on this issue, both online and in the manual, but I could not find anything relevant other than the admonishment that for general camera cleaning purposes one should steer clear from the use of any cleaners containing organic solvents. I viewed one suggestion for another product to use a drop or two of water on a soft lense cloth, but I don't know if this is reasonable in my situation with my particular product. Any knowledgeable and appropriately correct reasonable response offering guidance on this subject would be very much greatly appreciated. Thanks in advance.
