LIke... wow... tis I gonna try... eh, try posting some before and after result...joeyao said:1. Remove lens.
2. Switch to sensor clean mode.
3. Remove nozzle from vacuum cleaner.
4. Align opening of flexible tubing of vacuum cleaner to opening of camera body. For my case,
the diameter of the vacuum tubing is the same as that of the opening of the 20D.
5. Hit the power switch of the vacuum cleaner and leave it on for about 30sec.
6. Thats it! Saves me $21 if I get it cleaned at Canon.
