I have a Canon 300D that is now in need of a cleaning of the focus plate, mirror and sensor plate. The instructions to the camera doesn't show how to clean the mirror and focus plate but I assume compressed air will suffice.
For the sensor plate... This worries me a lot. The instructions says to lock the mirror up and then blow it with a rubber blower. My local photo shop (www.henrys.ca) suggest using compressed air. Does this sound good? They also suggested sending it to them for service.... they send it to Canon and it will be gone for no less than A MONTH .
I will buy a bottle of compressed air (made for camera cleaning) and give it a go unless anyone suggest not to.
Any suggestions for safe cleaning? |

I would not use compressed air except for on the out side of the camera, use the rubber bulb blower for the inside of the camera.

this is by far the best method I have seen for sensor cleaning. I would not use a blower inside the camera, as it just tends to move the dust around.
I bought the Walmart Spatulas and made my own tool, then just bought Pecpads to wrap it. Works great.
As far as cleaning fluids, unless you have a source of ultra-pure methanol with <5ppm residue (<1ppm is even better!) the eclipse is the way to go. Adorama will ship it by ground only, it cannot ship by air. Non-US buyers would have to source it in their own region, or find an alternate.
As far as alternatives, look for lab chemical suppliers, and ask for Ultra-pure Methanol. Specify <5ppm residue. Should run about $30 US for 0.5 liter.

I usually use an inexpensive rubber bulb blower to clean dust from the sensor and the inside of the mirror box. If there is something that I can’t get off with the rubber bulb I usually take my camera in to work and blow it off with nitrogen. We have a scrubbed/dried nitrogen system that I can set the pressure on that works very well for cleaning sensors. I usually blow the nitrogen from a 1/16’’ piece of PFA tubing with the nitrogen set to about 75 psig. Back when I had my D30 I was trying to clean it with a can of compressed air and some liquid came from the can and made some spots on my sensor. They were extremely difficult to get rid of so I would recommend not using compressed air unless you have it going through some sort of dryer.
The bulb I use I bought at Wal Mart for less than $3 in the baby section and it works 99% of the time.
