Don't spray anything on it to clean it.

There are cleaning brushes you can get made specifically for the purpose. If I can find the link, there is one company that makes one specifically for the sensor size in your camera (1.6) that a few people here use and say it works well.

I use a nasal syringe that was bought just for this purpose and kept in a sealed bag when not in use. With the camera in sensor clean mode I hold the camera upside down and blow over the sensor. Has worked great so far. I also blow off the lense mount, etc. before putting it away.

Taking care when you change lenses to protect the inside of the camera and the contact end of the lense will greatly help to reduce/eliminate dust particles. However, some zooms can suck dust in.

Garden hose and a dish towel should get most of it as long as you don't have alkaline water. Oh, and be careful about the amount of pressure in the hose. Too much might damage the sensor.

ok i have one of those rubber pumps with a nasal end... it produces a nice air flow, not too strong and can reach from far without having to stick it close to the camera .. would that work ?

There is a 1.6 version made for your model camera.

If you are going to use that pump, I would make sure it is clean inside and out and totally dry first. You can get a brand new and clean nasal syringe at any drugstore for like 2.00.

When I use the syringe the tip is fairly close to the sensor, but never touches it.

copperhill - I've been using the sensor swipe/sensor sweep for about 6 months now. Works GREAT.

If you live near a canon dealer, they will clean it for you for FREE, but i would only do that if blowing it off doesnt work,
i would not recomend you stick a brush in there, even if it is for the purpose, thats a big risk, you should take a picture of that and put it in the risk thread.
