Reading through the responses a majority of the respondents share my concern
about total immersion of the 390 radio parts.  As for cleaning materials
there was a wide variety of choices.  The most exotic was  sending it to
India and using fluorocarbon  spray which are still available there and I
guess legal to use.  Other choices were as follows: Ammonia / 409 Mix, 409,
ZEP Aerosolve, as well as soapy water and a tooth brush.

 

This radio has lots of dirt, so I think my approach on the latest radio will
be 409/ammonia mix with a tooth brush with a water follow up to limit any
corrosion from the ammonia.  As well as lots of elbow grease.

 

To follow up on Tisha's comment I have scrubbed a SP-600 down with soap on
the driveway and sprayed it down with a hose.  Let it bake in the Texas sun
for 2 days and set in my shop to dry for a month.  Got the radio back
together tipped on its side to align it and water ran out from somewhere,
even though I tipped the radio every which way during the drying process.

 

I want to thank you all for the comments . tom, N3LLL

 

One last questions:  Do the R-390 RF deck cans socketed and can be removed
similar to the R-390A?
