[Kenwood] Internal Dust - To Blow or not to blow?

[Dr. Gerald N. Johnson, electrical engineer]

The air compressor may introduce oil or water and it will blow
accessible grunge to inaccessible places. Its far better cleaning to use
a vacuum and soft paint brush to remove the grunge instead of dispersing
it. I use a milker inflation on the vacuum cleaner hose to get its
orifice gently down to about a half inch diameter. These days computer
cleaning kits include some sort of small aperture adapter for just such
cleaning. I use a 1/2" wide sign painter's brush, but an ordinary
bristly paint brush works fine to loosen dry grunge from corners.
