i been doing that and my cloth that came with my spy sunglasses, but its still oily like and seems to just be rubbing around now not actually coming off.
I pu some rubbing alcohol on tp and clean it with that. Then I follow up with the micro cloth.

Pretty much the same method I use. It works well, but you have to make sure that its not soaking wet, or that you don't push hard enough to squeeze out the alcohol because it can get under your screen. I figured that one out the hard way of course
