Default Wet clean

On a trip and had some dust in the upper of my pictures. Noticeable in landscape. Abou 3 or 4. Rocketblower didn't work, had a lot of lens changes. Stupid, but I didn't have much choice so I used a qtip and lightly swiped it. Now it looks like I have a smear, but hopefully not a scratch. I ordered swabs. I've read the directions, how hard is this to use without making matters worse or much worse. I'm hoping to get the specks and the smear out. How fragile is the sensor cover? I'm hoping a very light pass with a qtip didn't scratch it.

A clean, damp Q-tip wouldn't have hurt it, but there's no telling until you successfully clean the sensor anyway. The Copper Hill products are very good and very easy to use, and you're not likely to do any damage when using them.

How do I avoid having to make 20 passes with th copper hill kit? I've read about streaking, leaving dust on the edges etc. I just want to have my head on my shoulders correctly and do this without having to use 10 pec pads. I appreciate all the help.

As you swipe from one side to the other, swing the handle so that a different portion of the swab is in contact with the sensor while you swipe. That will keep you from dragging some particle across the sensor. If you do it smoothly and evenly, you shouldn't get any streaks. The swabs are exactly wide enough to cover the sensor from edge to edge. If you try to go back and clean up something you think you missed, you're more likely to make it worse than make it better.

I understand. From my perspective, I'd say that you found a horror story among the may success stories. Horror stories always attract more attention and concern than they actually deserve, and rarely tell the whole story.

If you have reservations about cleaning your own sensor, pay someone else to do it. Take it to your local camera shop and ask them to do it for you. If something goes wrong, they're on the hook for it, not you.

I'm going to try it tomorrow when I receive it. I'm very handy and do all my own Maintenence on everything. But I think you're right, the Internet does have horror stories, like this, and it makes you recoil a bit:

So, it didn't work?

Is it better or worse?
