Dennis, It took me 10 repetitions with the Copper Hill kit to get my sensor clean. The main reason, I think, was that I was not getting enough of the cleaning fluid to the end of the swab on both cleaning sides. I ended up using 4 drops total. I put 2 on right near the end on one side, then 2 on the reverse. Then, it is important to wait a few seconds before swabbing. Also, I had to swab horizontally, then vertically, alternately. So I ended up swabbing 5 times horizontally, and 5 vertically, following the Copper Hill instructions exactly.
It is important not to use the dirty part of the swab more than once, so angle the swab as it says in the instructions. Here is a link to the tutorial page--it may help you:
