For the bent panels:  I removed mine and then used a rubber mallet to pound them out flat.  Laid them on a piece of plywood on the concrete garage floor.  Checked them again on the flattest piece of floor by laying them on a towel and gently tapped them again.  They came out OK with no mars, dents, dings or scrapes.  For side and top-bottom panel dents and dings use a shop hammer and gently tap the ding repeatedly while laying the panel on a flat surface or using a small piece of steel for a back stop until it smoothes out.

 Do not be too worried about using
 distilled water. Chuck's videos show the
 garden hose cleaning method of working on the radio and it
 is just fine.
 
 Since you are pulling the decks and modules for individual
 cleaning and
 hopefully removing the panel meters you can treat the
 chassis like one big
 object for cleaning.
 
 Hot soapy water, lots of it, a soft scrub brush or paint
 brush and a bit of
 scrubbing power similar to doing pots and pans. Work the hot
 soapy water
 into all spots, clean out the bushings and all of the
 mechanicals on the
 front panel of dead grease and dirt. Rinse it all down with
 a garden hose
 (blast things a bit if you like).
 
 At the end you could use a gallon of distilled water to just
 do a
 splashdown rinse of the chassis to chase away any
 mineral-laden water. Blow
 it out with compressed air, then either leave it in the hot
 sun for a day
 or two or bake it gently in an oven at around 120 F for a
 few hours.
 
 Be nice to the potentiometers on the front wiring harness if
 you can. After
 things dry they might like a little bit of De-Ox-It, the
 same thing with
 the connector contacts.
 
 Since these radios were probably exposed to much worse than
 what you are
 going to do to them with the bath, what's the net-loss?
 
 Lots of the flat metalwork that may be dinged up or bent can
 be pulled off
 and re-flattened with a hammer and a hard surface. Some of
 the metalworking
 wizards could do even more.
