You sound very apprehensive after so many replies hehe...as I say before...if you don't feel confidence doing it...send it to the shop to get it done. Thousand plus dollar investment is alot of cash...it is not that hard to justify spending at least $59 a year to get it clean by the professionals. At least if they damage it..they will have to compensate you eheheh.
I am more concern you might be too nervous to carry out the cleaning. You don't have to do it like right now...or this week or this month. Here's a tip: Try using those cotton bud, or whatever material that has been suggested here and try to clean the front element of your lens or handphone screen. Get something that has dirt or fingerprint on it. Make sure it is a small piece so you know what it is like to work on a small space. If you can clean your lens or phone screen nice and clean, you are more or less ready to do the real thing.
