[Hallicrafters] Power washing a dusty, grimy rig??

[Ron Kolarik]

Power wash at your own peril. Even at low pressure it will force the cleaning solution
into places you don't want it and oven drying will not always dry it sufficently. Try 
some
Scrubbing Bubbles on it and if you mix up a cleaning solution with water use distilled
or de-ionized water.  Your choice but if it was me I would go for labor intensive over
fast if it was a piece worth conserving.
