[GreenKeys] Re: penetrating oils

[Ralph Mowery]

Kroil is a very good cleaning type oil.  Some of the penetrating type
oils will turn to 'glue' if left on too long.  Years ago I made the
mistake of using some  Liquid Wrench on the selector of a tty  unit and
after a few days it set up .  I had to take the whole area apart and
really give it a good cleaning.  It looked as if I had used varnish on
the selector.  

Below I am listing a cheap mixture for cleaning that Ed Harris ( a gun
writer among other things) has developed. I have used it for several
years and it works very well.  Just don't get it on the non metalic
parts or leave it on them very long.  Don't mix in the lanolin for
cleaning.

================================

CONTENTS:     Ed's Red Bore Cleaner

1 part Dexron II or IIe ATF, GM Spec. D-20265 or later.
1 part Kerosene - deodorized, K1
1 part Aliphatic Mineral Spirits, or Stoddard Solvent,
  Fed. Spec. TT-T-2981F, CAS #64741-49-9 (aka "Varsol")
1 part Acetone, CAS #67-64-1.

(Optional up to 1 lb. of Lanolin, Anhydrous, USP per gallon, aka
Lanolin, Modified, Topical Lubricant, from the drug store)

MIXING INSTRUCTIONS:
Mix outdoors, in good ventilation.  Use a clean 1 gallon metal or
chemical-resistant PET pr PVC plastic container.  Do NOT use
HDPE, as it is breathable abnd the acetone will evaporate.  Also
ER will eat HDPE in about 6 months, making a heck of a mess!

Add the ATF first.  Use the empty container to measure the other
components, so that it is thoroughly rinsed.  If you incorporate
the lanolin into the mixture, melt this carefully in a double
boiler, taking precautions against fire and pour it into a larger
container, rinsing the lanolin container with the bore cleaner
mix, and stirring until it is all dissolved.

I recommend diverting a small quantity, about 4 ozs. of the 50-50
ATF/kerosene for use as an "ER-compatible" gun oil.  This can be
done without impairing the effectiveness of the resulting mix.
