[R-390] VFO assembly wash or not to wash

[djelatnik slavonija]

Hi there..

Currently my process of restoring and rebuilding of R390A receiver is
in step on gear cleaning and after this only part, beside main chasis,
is VFO.

Please advice me on this mather..it is recomended procedure to wash
entire VFO (inside and outside) with water/detergent solution or it is
better to leave VFO intact (covered with dust and other particles)?

Thanx in advance
