I have and find it works great. Everything I see and clean goes away.
Are you adjusting the focus on it? You should see a crisp clear image of the sensor.
I hate to ask this, but have you lifted your mirror for cleaning before you look? If not you are looking at your mirror, not at the sensor.
Keep in mind the image is upside down and backwards from what you see when looking directly at the sensor.

Also, when you look through the view finder of your full frame camera with lens attached and camera turned on, would you be able to see the spots that you see before you take the photo? Hope this makes sense!

I suggest no to that question. The spots on the sensor are not a part of the viewfinder system, so you will have to rely on the captured image to see what's on the sensor.

How do spots get on the sensor - during lens switching, inadequate lens/body connection. If dust, would not a squirt of air from rubber bulb do.

I might add that it is rare you need a "wet clean" of the sensor anyway unless you have the situation where you've glued dust to your sensor due to condensation (cold camera, warm room). You really should get it clean once, and try using the dust brush more often. It works great and picks up the majority of what would bug you. Wet clean once a year, and dust brush the rest.
F22 is highly overrated.

Your advice neglects to consider the increasing presence of camera lubricant on the sensor. Blowing will not remove it.

Copperhill is a great product. It will generally require several swipes but the result is usually an immaculate sensor. The loupe is worthless. Just use a bright light/lamp to examine it.

I didn't know that. Lubricant, like grease, oil and lots of it, like dripping off sone gears.

Yep. Something like that. If you Google it I think you will find that it is becoming more of a concern these days.

Very few zoom lenses are airtight. Every single time you adjust the focal length you suck air into the camera... and air contains dust.

Say Cholly, would that also include an IF zoom lens?

Thanks, I was thinking of the 70-200 where nothing moves except inside of the lens , more like a prime. I know that a 100-400mm zoom sucks air and lot of it too. I agree with your earlier statement that most all zoom lenses do have a problem with dust. Your reply did make me think. Thanks and have a good weekend.

Sometimes it helps. Always the first step to take.
Usually it doesn't remove spots on the sensor. They manage to get a grip somehow. But it does help clean out dust particles that are future spots.
I now find that the Arctic Butterfly works most of the time for most of spots. It is a brush that has a motor to rotate it and create a static charge to collect the dust and then to disperse what it collected. When it doesn't work I use the wet cleaning. And I always use the brush after wet cleaning because it often leaves pieces of the gauze.
If go for one an Arctic Butterfly and live in the U.S. buy from Adorama or another good camera dealer that has them: not from the company directly. Besides their higher prices they want exorbitant amounts to ship from CA to US.
