[R-390] Benchmark - R390A odd-ball cleaning and lubrication

[Jim]

I used diluted Simple Green to clean my S-line and a few other BA's...

Granted, this is not the challenge of the R-390A gear train...but

Simple Green with artist brushes for agitation and a through rinse with 
distilled water worked wonders...

Compressed air to clear off the standing water and a day or so in the bright 
hot sunshine did the trick...

(Does anyone remember bright, hot sunshine?)
