Digital sensor cleaning, my way

After reading a lot of  "horror" stories about this issue on the internet I postponed this as long as possible and a bit more. The only thing I had been doing this first year was occasionally blowing with a CO2 blower. After more than one year,  10000+ exposures and countless lens changes with my Canon EOS 20D it was no way to avoid the big cleaning anymore. After through investigation of various internet sites, I bought this equipment:

 

Pec-Pad (100 wipes) or E-Wipe (25 wipes)

Eclipse cleaning solvent

14 mm Sensor Wand

Refill cartridges for American Recorder CO2 blower

Arctic Butterfly
 

 
The Pec-Pads are not approved by the producer for sensor cleaning, but the Norwegian importer sell it for this purpose too. I have seen on the internet that others have been using it without problems. It looks to me that it is possible that the    Pec-Pad wipes can loose a fibre or two, but I don't see this this as a problem. You can just blow it away.

How to do it, my way: 
If you want to see the difference cleaning makes, take a picture of a bright surface (i.e. the sky) before and after. Overexpose with about one stop.

1. Find a place with minimum dust. I did it outside. It is winter and very little particles in the air.
2. Use the blower on the inside of camera , including the sensor. You can use a hand blower instead of CO2.
3. Wrap the Pek-Pad wipe around the Sensor Wand and fasten it with tape. Use a good amount of solvent on the wipe. It shall not be dripping wet. If so, fluid can find it's way into places you don't want it to go, even though the Eclipse solvent evaporates quickly. Drag it across the sensor, and back again, using the other side. Change wipe and do this as many times as you find necessary. You can apply a bit more pressure each time, but still always light pressure.

I used tree wipes for cleaning the sensor. I did not get all the spots, but more than 99%. If I had used more wipes and rested the Sensor Wand with the wet wipe directly on the location of the remaining few spots, I think I would have been able to get the sensor 100% clean. I will try this next time I clean the sensor.

This is a very economical way to clean sensors. All you really need are Pec-Pads, Sensor Wand (this you can make your self from a rubber spatula), Eclipse cleaning fluid (or other cleaning agent you trust) and a blower. All together I think it is possible to get this for less than USD 25-30, if you make your own sensor wand and buy a cheap hand blower from your pharmacist. You can clean your camera MANY times with this equipment.
 If you decide to use E-Wipes it will be a somewhat more expensive since 100 Pec-Pads are USD 7,25 and 25 E-Wipes are USD 25.  I have not tried E-Wipes.  

The Arctic Butterfly I bought mainly for keeping the sensor clean in the future. Will report how this works as well.
Will add a few more pictures from the cleaning procedure later.
