What is the best way to clean the lens of my Canon Powershot 850 IS?

What is the best way to clean my camera lens? I noticed that there are a few dust specs on it and I don't want to compromise my picture quality. What is the best way to clean it? Thanks

First get a bulb-type blower brush to remove the dust. Then get a lens cloth at the camera store. You can breathe on the lens for stubborn smudges. If your lens accepts filters, buy a HAZE/UV filter or a Skylight filter - or both - and keep one of them on your lens at all times unless using a polarizer. The filter protects your lens from dust as well as the possibility of getting scratched or getting an acidic smudge or fingerprint on it. Plus, the HAZE/UV filter removes atmospheric haze in scenics; the Skylight removes the bluish tint seen in shaded mountains or snow.

If your lens doesn't accept filters, the manufacturer probably offers an adapter so that it can. Buy it and the filters.

You can get a blower brush to remove dust. To clean it more than that use clean lens tissue, wipe very gently.

You've gotten 2 excellent answers. I will add this, do not buy ANY liquid to put on lens as they tried to sell me at Best Buy.
