My digital camera sensor got dirty enough and it was no longer possible to clean it just by softly blowing air to it. So I looked for a more powerful cleaning solution. After some searching I decided to try Pentax Image Sensor Cleaning Set O-ICK1. It looked simple and didn’t require any liquids. Does it work?
I wasn’t much successful when carefully following the instruction manual. But then I applied somewhat stronger pressure than suggested and it started to work very well. My sensor is sufficiently clean now.
Here are sample images (crop of the same resized area) before and after the cleaning (please ignore the sky in the background and look just at the dust spots):
