OK, I've cleaned my sensor in the past using the dry "sensor brush" method with success. This time, there are 2 spots of something that wont come off. It's not much, but it bugs me they are there and refuse to come off. So, what's the next method to use that will get off more "stubborn dirt" if you will... Thanks for any suggestions!

I highly recommend the copperhill method.

Thank you for the info. Looks like one of those may be on order here shortly... :-)

the possibility might exist that you have dead pixels in your sensor
do the spots look like this:

I thought about dead pixels...but, the last time I cleaned it with the brush, I couldn't see ANY spots left. So, unless some died in the intervening time, I don't think so. Is that possible? Do pixels die as a camera gets older? Maybe they do... I don't know...

Looked more like dirt/dust to me. "Fuzzy" blobs when taken at small aperature (f/26?) of a white surface. Not sharp distinct pixels. Looks like the dirt/dust that the brushes have removed in the past. And which they removed most of this time (except for these 2 stubborn ones...). I ordered a "pec pad" kit. I'll see if it gets them off. :-)

I went to the camera store today to buy a new 50mm lens and have my camera sensor cleaned.
His method was first tried the dry blower..
that didn't work so he broke out a sensor swab, and some sort of chemical took him about 20 minutes to finally get it off.
he said sometimes because of the heat the sensor can put off, the dust or whatever can actually get baked on... eep
My sensor is clean now so I reccomend the camera shop:) |

The sensor will never get anywhere near hot enough to "bake on" anything. Things do get stuck tightly now and then, but not due to heat. Unless you're leaving that cam in the car all day ;-)

It's also possible to have defects in the highpass filter covering the sensor. I had several on my 10D when I bought it. It also appeared to have uniformly discolored bands around the perimeter. I sent it in and they replaced it free. All's well now.
