"Ed's Red" Bore Cleaner... Home-Mix Really Works!

By C.E., "Ed" Harris         Updated and Revised 7-2-96

Four years ago I mixed my first "Ed's Red" or "ER" bore cleaner and hundreds
of users have told me that they think this home-mixed cleaner is more
effective than commercial products.  I urge you to mix some and give it a
fair trial, compared to whatever you have been using.  Competitive shooters,
gun clubs and police departments who use a gallon or more of rifle bore
cleaner annually can save by mixing their own, and they will give up nothing
in safety or effectiveness.

This cleaner has an action very similar to standard military issue rifle
bore cleaner, such as Mil-C-372B.  Users report it is more effective than
Hoppe's for removing plastic fouling in shotgun bores, or caked carbon
fouling in semi-automatic rifles or pistols, or in removing leading in
revolvers.   It is not as effective as Sweets 7.62, Hoppe's Bench Rest Nine
or Shooter's Choice for fast removal of heavy copper fouling in rifle bores.
However, because "ER" is more effective in removing caked carbon and
abrasive primer residues than other cleaners, metal fouling is greatly
reduced when "ER" is used on a continuing basis.

I originally came up with this mix because I am an active high power rifle
competitive shooter and hand loading experimenter who uses a lot of rifle
bore cleaner.  I was not satisfied with the performance and high price of
commercial products.  I knew there was no technical reason why an effective
firearm bore cleaner couldn't be mixed using common hardware store
ingredients.  The result is inexpensive, effective, provides good corrosion
protection and adequate residual lubrication so that routine "oiling" after
cleaning is rarely necessary, except for long-term storage of over 1 year,
or harsh service environments, such as salt water exposure.

This formula is based on proven principles and incorporates two polar and
two nonpolar solvents.  It is adapted from the one in Hatcher's Notebook for
"Frankford Arsenal Cleaner No.18," but substituting equivalent modern
materials.  I had the help of an organic chemist in doing this and we knew
there would be no "surprises."  The original Hatcher formula called for
equal parts of acetone, turpentine, Pratts Astral Oil and sperm oil, and
optionally 200 grams of anhydrous lanolin added per liter.  Some discussion
of the ingredients is helpful to understand the properties of the cleaner
and how it works.

Pratts Astral oil was nothing more than acid free, deodorized kerosene.  I
recommend "K1" kerosene of the type normally sold for use in indoor space
heaters.  Some users have reported successful substitution of civilian
aviation grade kerosene such as Turbo-A.  I am reluctant to "recommend"
substitution of aviation grade kerosene, because the effects upon firearm
components of the additives required in aviation fuels are unknown.  Some
"jet-fuels" are gasoline/kerosene blends and absolutely should not be used,
because of their increased flammability.

An inexpensive, effective substitute for sperm oil is Dexron (II, IIe or
III) automatic transmission fluid.  Prior to about 1950 that most ATF's were
sperm oil based, but during WWII a synthetic was developed for use in
precision instruments.  With the great demand for automatic transmission
autos after WWII, sperm oil was no longer practical to produce ATF in the
quantity demanded, so the synthetic material became the basis for the Dexron
fluids we know today.  The additives in ATFs which include organometallic
antioxidants and surfactants, make it highly suitable for inclusion in an
all-purpose cleaner-lubricant-preservative.

Hatcher's original Frankford Arsenal No. 18 formula used gum spirits of
turpentine.  Because turpentine is expensive today, and is also highly
flammable, I chose not to use it.  Safer and cheaper is "aliphatic mineral
spirits," a petroleum based "safety solvent" used for thinning oil based
paints and also widely used as an automotive parts cleaner.  It is commonly
sold under the names "odorless mineral spirits," "Stoddard Solvent" or
"Varsol".

Acetone is included in "ER" to provide an aggressive, fast-acting solvent
for caked powder residues.  Because acetone is a highly volatile organic
solvent, it is recommended that users leave it out if the cleaner will be
used in enclosed spaces lacking forced air ventilation.  The acetone in ER
will evaporate, liberating volatile organic compounds (VOCs) into the
atmosphere unless containers are kept tightly closed when not in use.  The
cleaner is still effective without the acetone, but it is not as
"fast-acting."

There isn't anything in Ed's Red which chemically dissolves copper fouling
in rifle bores, but it does a better job removing on carbon and primer
residue than anything else which is safe and commonly available.  Numerous
users have told me, that exclusive use of "ER" reduces copper deposits,
because it removes the old impacted powder fouling which is left by other
cleaners, which reduces the abrasion and adhesion of jacket metal to the
bore surface, leaving a cleaner surface condition which reduces subsequent
fouling.  Experience seems to indicate that "ER" will actually remove metal
fouling it if you let it "soak," so the surfactants will do the job, though
you have to be patient.

Addition of the lanolin to ER bore cleaner mix is entirely optional.  The
cleaner works quite well and gives adequate corrosion protection and
lubrication for most users without it.  Incorporating the lanolin makes the
cleaner easier on the hands, and increases lubricity and film strength, and
improves corrosion protection if weapons will be routinely exposed to salt
air, water spray, industrial or urban corrosive atmospheres, or if you
intend to use the cleaner as a protectant for long term storage of over 1
year.

If you use other protective films for adverse use or long term storage you
can leave the lanolin out and save about $8 per gallon.  At current retail
prices you can buy all the ingredients to mix ER, without the lanolin for
about $10 per gallon.  I urge you to mix some yourself.  I am confident it
will work as well for you as it does for me and hundreds of users who got
the "recipe" on the Fidonet Firearms Echo.

CONTENTS:     Ed's Red Bore Cleaner

1 part    Dexron II, IIe or III ATF, GM Spec. D-20265 or later.

1 part    Kerosene - deodorized, K1

1 part    Aliphatic Mineral Spirits, CAS #64741-49-9, or may substitute
          "Stoddard Solvent", CAS #8052-41-3, or equivalent, (aka "Varsol")

1 part    Acetone, CAS #67-64-1.

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

MIXING INSTRUCTIONS FOR "ER" BORE CLEANER:

Mix outdoors, in good ventilation.  Use a clean 1 gallon metal,
chemical-resistant, heavy gage PET or PVC plastic container.   NFPA approved
plastic gasoline storage containers are also OK.  Do NOT use HDPE, which is
permeable, because the acetone will eventually evaporate.  The acetone in ER
will also attack HDPE, causing the container to collapse, 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.  Pour the melted lanolin 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, up to 4 ozs. per quart of the 50-50
ATF/kerosene mix for optional use as an "ER-compatible" gun oil.  This can
be done without impairing the effectiveness of the remaining mix.

2.   FIRST AID, If swallowed DO NOT induce vomiting, call physician
     immediately.  In case of eye contact immediately flush thoroughly
     with water and call a physician.  For skin contact wash thoroughly.

3.   Use with adequate ventilation.  Avoid breathing vapors or spray mist.
     It is a violation of Federal law to use this product in a manner
     inconsistent with its labelling.  Reports have associated repeated and
     prolonged occupational overexposure to solvents with permanent brain
     and nervous system damage.  If using in closed armory vaults lacking
     forced air ventilation wear respiratory protection meeting NIOSH TC23C
     or equivalent.  Keep container tightly closed when not in use.

INSTRUCTIONS FOR USING
"Ed's Red (ER)" Bore Cleaner:

1.   Open the firearm action and ensure the bore is clear.  Cleaning is most
     effective when done while the barrel is still warm to the touch from
     firing.  Saturate a cotton patch with bore cleaner, wrap or impale on
     jag and push it through the bore from breech to muzzle. The patch
     should be a snug fit.  Let the first patch fall off and do not pull it
     back into the bore.

2.   Wet a second patch, and similarly start it into the bore from the
     breech, this time scrubbing from the throat area forward in 4-5"
     strokes and gradually advancing until the patch emerges out the muzzle.
     Waiting approximately 1 minute to let the bore cleaner soak will
     improve its action.

3.   For pitted, heavily carbon-fouled "rattle battle" guns, leaded
     revolvers or neglected bores a bronze brush wet with bore cleaner may
     be used to remove stubborn deposits.  This is unnecessary for smooth,
     target-grade barrels in routine use.

4.   Use a final wet patch pushed straight through the bore to flush out
     loosened residue dissolved by Ed's Red.  Let the patch fall off the jag
     without pulling it back into the bore.  If you are finished firing,
     leaving the bore wet will protect it from rust for 1 year under average
     conditions.

5.   If the lanolin is incorporated into the mixture, it will protect the
     firearm from rust for up to two years.  For longer term storage I
     recommend use of Lee Liquid Alox as a Cosmolene substitute.  "ER" will
     readily remove hardened Alox or Cosmolene.

6.   Wipe spilled Ed's Red from exterior surfaces before storing the gun.
     While Ed's Red is harmless to blue and nickel finishes, the acetone it
     contains is harmful to most wood finishes).

7.   Before firing again, push two dry patches through the bore and dry the
     chamber, using a patch wrapped around a suitably sized brush or jag.
     First shot point of impact usually will not be disturbed by Ed's Red if
     the bore is cleaned as described.

8.   I have determined to my satisfaction that when Ed's Red is used
     exclusively and thoroughly, that hot water cleaning is unnecessary
     after use of Pyrodex or military chlorate primers.  However, if bores
     are not wiped between shots and shots and are heavily caked from black
     powder fouling, hot water cleaning is recommended first to break up
     heavy fouling deposits.  Water cleaning should be followed by a
     thorough flush with Ed's Red to prevent after-rusting which could
     result from residual moisture.  It is ALWAYS good practice to clean
     TWICE, TWO DAYS APART whenever using chlorate primed ammunition, just
     to make sure you get all the corrosive residue out.
