Better to open the lens up and clean the lens properly. I've also tried similar trickery you use, but it never seems to do the job well enough, especially since the back element is critical for image quality.
If opening is not an option, then I'd first blow the dirt away, then maybe vacuum the dirt gently and finally use a largish diameter soft object, wrap disposable cleaning paper over it, put a drop or two of very quicly vaporizing cleaning agent on it and then slowly and gently clean the lens, repeating with a new clean tissue (or a clean part of the old one). Eve if the tissue looks clean, it will be greasy and it's not a good idea to spread the grease, so after each swipe it is a good idea to use a clean portition of the paper (with a new drop of the cleaning liquid). |

It s a bit controverse tool, not everyone agrees on it s utility, after i clean such lens elements by blowing away any dust and other particles, i use Lens Pen. It proved a good handy tool to reach those deep lens elements, not perfect for everything of course, but wich tool is, anyway?

The usual tools: blower, soft artists brush, long q-tip (ear bud), eclipse, naptha, distilled water, pec-pad.
One lens I decided to do it right. The rear tube joint was under the tripod mount. After removing the tube, the rear element was well exposed for cleaning. Perfect. I didn't touch it. Since then I check with flashlight before going to the trouble. So far blower & brush have been enough, even for very dusty lens that had been sat end up without a cap! _________________ ☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮ like attracts like! ☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮

One word of caution - Acetone is a solvent to most plastics, and most q-tips (at least in my area) have plastic sticks. If you are using acetone, make sure you buy the expensive q-tips with the paper sticks. _________________ Sigma DP1, Nikon D40 (hers ), Polaroid x530, Pentax P30t, Pentax P50, (P30t/P50 K-A to Nikon F body mount conversion)
