My favorite camera flings OIL...so when I clean its sensor, it usually takes FOUR swabs. Other cameras I have had never flung oil, so they could be neatly done with one, or two swabs. Congratulations on your act of having taken this bull right by the horns and wrassling it into submission! You've now got the camera back to working order and have not sunk 300 pounds Sterling into it. Way to go Zoe!
