Patrick Norton gives this tip to clean your camera lens.
1. Clean off your lens with a brush or air.
2. Use 90% Isopropol alchohol and a 5 to 10 mixture with water.
3. Put it onto your microfiber rag and twist it until it stops dripping.
4. Then rub it against the lens lightly to remove any spots.
He also recommends using the LensPen as an alternative.
