I found a new method to clean my camera sensor and it is worth to think about it.
All you need is a fluid called "disco film" which is made on a pure water basis to clean the old black records (and which you can buy in some record stores), a little sheet of paper and some quiet hands (this method is definitely NOT for alcoholics and parkinson people!)...
More information here (in german):

Disco film works fine with dry dust and dirt but doesn't remove fat and fingerprints!
Here's my 1D MkII sensor before disco film cleaning:
