Dirt, dust, grease, oil, films or other contaminants can build up on generator windings and create problems. Visual checks and maintenance that includes the following should be performed by trained personnel routinely.
Check for movement or loosening of wires
Inspect and clean all leads, electrical and electronic components
Check insulation using a megger insulation tester
Actual cleaning procedures range from normal cleaning for dust and dirt to extreme cleaning and recoating for heavy grease, dirt and chemical buildup. A cleaning schedule should be developed based upon application and location. Generally generators should be cleaned.

Whenever megger test results are unacceptable
It is important to note that applications in extremely dirty or salty, humid environments may require more frequent cleaning (i.e. rock dust, marine aux., outdoor installations, etc. may require weekly cleaning).
