[ARC5] cleaning radios

Fri Apr 10 20:45:12 EDT 2009

I just tried something for the rust stain still remaining on the bottom 
cover.Toothpaste.Actually Crest brand Baking Soda & Peroxide Whitening 
formula.It worked!Didn't scratch the surface any.There is still 
discoloration of the metal but it is not rust staining but probably 
oxide or some resultant from electrolosis.

BTW I could use a 1626.Doesn't have to be the brightest bulb in the 
lamp.I do not think I will put power to this Tx,just would like to have 
a fairly decent example.I now have the series T15 to T-23,some very 
good but most are average.Please don't tell me there's a T-14,T-13, 
etc.I want to be done with the search! and get to the work!

Jay & the gang -

  Good luck getting that little jewel cleaned up Jay.

  I recently bought an ultrasonic cleaner from Harbor Freight and am
having real good luck with it (their number 95563-3VGA).  I would not
want to put a painted part in it but it does a real good job on smaller
pieces, either plated or unpainted -  might be useful in cleaning small
parts or hardware in that T-15.  The cleaner has a built-in heater,
which is pretty much essential. HF sells a detergent for use in the
cleaner -  I believe it is just repackaged Alconox (common
industrial-grade detergent).

  Has anyone ever tried etching for badly corroded Command Set sheet
metal parts?
