Procedures to Clean Your M1842 Springfield Musket
(Smoothbore and/or Rifled)

Regimental Quartermaster, Inc. has prepared these instructions to assist you in the care and maintenance of
your M1842 Springfield black powder musket. We do not recommend this type of in-depth cleaning for
an original/antique musket as it will significantly devalue your musket.

You will need the following items to properly clean your musket:

Wooden Handle Awl: The awl is used for removing caked black powder from around the musket cone on the
rear of the barrel and other hard to reach areas.
T-Handle Nipple/Cone Wrench: Made of steel, these cone wrenches are for the removal and installation of
the musket cone. Use the wooden handled or Musket wrench for cones that are difficult to remove.
Wooden Handled Cone Wrench: Made by John Zimmerman, Master Gunsmith out of Harpers Ferry, WV,
this solid tool is useful for removing the nipple/cone from most barrels. Ensure that the wrench seats COMPLETELY
over the cone to prevent stripping the cone.
Wire Brush: The wire bristles are perfect for cleaning black powder and rust off of difficult to reach areas but do
not use it on any blued surfaces or brass, as the bristles are made of steel and result in damage.
Revolver Wedge Punch: Made of Aluminum, this tool is typically used to remove the wedge from a revolver;
however, it is also great to remove/knock loose your bands from the musket if they are rusted tight onto the barrel.
Toothbrush: Great for cleaning the small nooks and crannies of your musket, especially around the front
and rear sight and on the internal mechanisms inside the lockplate.
Band Spring/Tumbler Punch: Original punch set is perfectly sized to fit both original and
reproduction muskets. Used to punch out the band spring pins, ramrod spring/trigger pins as well as
separating the hammer from the tumbler.
Musket Wrench: Whether original or reproduction, this wrench is perfect to remove the musket cone as well
as the screws of the musket. If reproduction, we recommend grinding down the ‘leafs’ with a sander for a
solid fit into screw heads.
Cleaning Rod: Cheaper and more durable than a ramrod, used to run patches and brushes down the inside
of the barrel to remove rust and black powder. Four sections used for most muskets, five sections for the
Springfield M1842 barrel.
Brass Button Jag: Used to run cotton patches down the length of the barrel. Ridges along the side of the
jag grip the cotton patch and ensure the patch comes out of the barrel. Ensure you use the proper size jag
for your musket’s caliber.
Brushes: Used to remove rust and black powder from the barrel. Recommend you spray the brushes
with ballistol prior to chasing it down the barrel to prevent them from getting stuck inside. The cotton
brush can be cleaned and reused multiple times.
Hammer: A brass hammer is effective while, at the same time, made of a softer metal that will not
mar/damage the steel of your musket.
Screwdriver: Flathead screwdriver made of steel. Screws on the muskets are easily damaged.
Recommend using a screwdriver that fits snugly into screw heads or use a grinder to shape the
screwdriver head for a perfect fit.
Mainspring Vise: Used to remove/install the mainspring from the lockplate. A must-have tool
as the use of pliers or vise grips will mar the metal of the mainspring and potentially over stress the
spring, causing it to break.
Ballistol: Ballistol cleans and removes all types of bore fouling, dissolves black powder and corrosive residue.
Ballistol is fully compatible with all metals including aluminum. Recommended for use with original
muskets as well as it is non-abrasive and will not damage the patina on original muskets.
Linseed Oil: Used to rejuvenate the wood of the stock and weather-proofing. Multiple coats may be needed as
the wood will soak in the oil, preventing it from drying out and cracking.
Cone/Nipple Pick: Made of steel, the long or short pick is used to clear out the cone hole of debris and
black powder. As noted to the right, the end may be formed to facilitate cleaning of the bolster’s
ignition hole into the barrel.
NEVR-DULL: Works wonders on all types of metals, a little wadding goes a very long way and will
simplify cleaning your musket.

Steel Wool: Not for use on blued steel unless you wish to remove the bluing, or brass. Easily removes rust
and corrosion from metal, but use sparingly and in conjunction with Ballistol.
Scouring Pads: Cheap but effective, very useful if cut into smaller, more manageable squares and used on steel.
Use with ballistol to remove caked grime, black powder and/or rust. Will remove the bluing off of a blued barrel.
Dremel Tool: This versatile tool will allow you to quickly polish brass, grind down metal, and shape the stock
as needed. Definitely a ‘force multiplier’ for your tool box. Cord and cordless models are available.

Often a musket will receive a quick cleaning in the field. Typically this is done by running hot water down
the barrel to remove any black powder residue along with a quick wipe of the exterior. However, we
recommend the owner disassemble the musket after use to remove any excess water from the inside of the
lockplate and underneath the barrel bands which may result in significant rust and potential damage.
Every 6-12 months the wood should receive a coat of linseed oil to ensure the wood does not dry out
and begin forming cracks. We begin with our ArmiSport M1842 Springfield Smoothbore Musket:

STEP 1: Ramrod
This musket has seen little care in the past. Rust has formed underneath the barrel bands, inside the lockplate,
and the wood is very dry. To begin, remove the ramrod and place it to the side. To clean the ramrod, use
Ballistol and a couple of cotton patches to remove surface rust. If there is significant rust, spray the ramrod
with Ballistol and wipe it down with wire wool or a wire brush.

STEP 2: Lockplate

Using a screwdriver or musket wrench, remove the lockplate screws from the stock opposite the lockplate.
Once removed, carefully use your awl to remove the side plate from the stock and set it aside with the washers.
For our purposes, we are using an original M1842 musket wrench as we have found modern screw drivers tend to
strip the heads. The screwdriver we use is over 40 years old and the head has been ground with our
Dremel to ensure the screwdriver fits perfectly into the screw heads to prevent accidentally damaging the heads.

Pull the hammer back to ‘safe’ and carefully remove the lockplate and its components by sliding it out from the stock.

If it is difficult to remove, reinsert the lockplate screws and lightly tap on the head with the brass hammer to push the
lockplate out from its well. We recommend using a brass hammer as it is a lighter metal and will not damage or mar
the metal components on the musket. Once removed, your components will look like this:

STEP 3: Lockplate Internals
Hold the lockplate in your hand and with your thumb pushing up on the sear, let the hammer fall back to
the ‘down’ position which will release tension on the main spring. Using a main spring vise (your choice,
original or reproduction) slide it over the main spring and then tighten the vise until it comes off of the stirrup (which is attached to the tumbler).

Remove the mainspring screw and, using light pressure, gently remove the main spring from the l
ockplate. With the mainspring removed, use your screwdriver to first loosen the sear spring screw
and (1) then pop the sear spring off of the lockplate. (Note: If there is persistent rust, liberally spray
the entire lockplate and its components with Ballistol. This will help remove the rust while preventing
damage from seized screws and potentially having them break off). Continue to loosen the sear spring
screw and (2) remove. (3) Remove the sear and sear screw and (4) the bridle and bridle screw (ensuring
you keep the screws with their corresponding parts). Turn the lockplate over and remove the hammer screw.
If the hammer does not come off of the tumbler, insert the tumbler punch (large end) into the tumbler and
knock it off of the tumbler using the brass head hammer. Once the hammer comes off the tumbler, place it to
the side and then remove the (5) tumbler from the lockplate. You are now ready to being cleaning the components:

All components should be sprayed with Ballistol and scoured using the wire brush. Once all rust and/or black
powder residue has been removed from the parts, wipe them down and reassemble in reverse order from above.

STEP 4: Band Springs and Bands
With the lockplate complete, set it aside along with the lockplate screws and washers. Take your musket and
locate the band springs. With your thumb, depress the band springs one at a time and remove the top, middle,
and bottom band springs in that order. If the bands do not budge, use the revolver wedge punch and hammer
to gently tap the band springs off of the barrel and stock. The revolver wedge punch is made of aluminum and
thus will not damage or mar the steel barrel and bands. Once the bands are removed, locate the holes opposite
the band springs and use the thin end of the band spring/tumbler punch to punch out the springs. Be very careful
of where the pins attach to the springs as the pins can easily snap off and then have to be replaced. Place the
band springs with their corresponding bands as the pins’ length may determine their placement in the stock.

STEP 5: Barrel
Remove the cone with the T-handle wrench. Unscrew the tang screw from the back end of the barrel and remove
the barrel carefully from the stock. Wipe down all the band springs, bands, cone and tang screw with Ballistol and
cotton patches. Make sure the insides of the bands are cleaned well as the bands tend to rust where they meet with
the barrel. Excessive rust could permanently mar the barrel and bands, potentially damaging them beyond repair.
If necessary, rub down the rough/rust spots with Ballistol and steel wool. Replace the cone if needed.

To clean the interior of the barrel, use a simple mix of dish soap and hot water. (NOTE: We do
not recommend using rubbing alcohol or hydrogen peroxide in the barrel as it is very caustic
and will result in pitting your barrel.) Pour the hot water mixture down the barrel, plug the bolster
hole and barrel end, and shake the barrel allowing the water to loosen up any black powder residue
inside. Repeat several times until the water comes out clear.
Assemble your cleaning rod, screw on a button jag, and apply some Ballistol to a cotton patch. Run
the patch down the length of the barrel to remove any remaining black powder and rust. Repeat until
the patch comes out clean. With the interior complete, use a steel wool pad and/or steel wool
with Ballistol to remove any rust and black powder from the exterior of the barrel. Continue cleaning
the barrel until all rust and black powder has been removed. Place the barrel to the side.

STEP 6: Ramrod Spring
Forward of the lockplate is an additional pin in the stock. This pin secures the ramrod spring into the stock.

Use the band spring / tumbler punch to remove the pin and ramrod spoon. With the pin and
spring removed, wipe them both down with ballistol and a cotton patch. Ensure that all rust and
grit is removed from the spring and set it aside.

STEP 7: Trigger Guard Assembly
Turn the stock and locate the trigger guard assembly. Unscrew the two wood screws and
then remove the assembly.

Additional Ballistol may be needed on the trigger screw and trigger guard nuts. Gently remove these as
you do not want to strip the screws. Once all parts have been removed, clean the metal with
Ballistol and a wire brush/steel wool. Once complete, reassemble the trigger guard assembly
(make sure that you put the trigger on BEFORE the trigger guard) and set it to the side.

STEP 8: Buttplate
The buttplate receives some of the worst wear as a musket often rests on the ground allowing
moisture and dirt to get into the screws and between the butt plate and stock. Clean off the screw
heads with water or Ballistol removing all debris from the heads themselves. Carefully unscrew
and place the buttplate and screws to the side.

Liberally apply Ballistol to both sides of the buttplate and remove all traces of rust. Clean the screws,
particularly the undersides of the screw heads (where they meet the metal of the buttplate), and
set them aside. Once completed, the wood stock is all that should remain.

STEP 9: Stock
The least cared for part on your musket is most likely the wood stock. Constructed from dark walnut,
wood is very susceptible to temperature and humidity causing it to dry out. The remedy for this is
several liberal applications of Linseed Oil (natural is preferred, boiled is okay), which can be purchased
from Lowe’s, Home Depot, Walmart or even your local hardware store. However, linseed oil is VERY
flammable and care must be taken when applying. All linseed soaked materials should be disposed of
immediately after use. Using a cotton cloth or paper towels, soak your material and ‘paint’ the oil onto the stock.

Treat both exposed areas as well as the barrel groove, ramrod trench, lockplate well, trigger guard well and
the buttplate with linseed. Set the stock aside to dry in a well ventilated area, it may take several hours to be
absorbed. Several applications may be required. Continue applying until the wood ceases to absorb the surface oil.
Wipe down when complete. You are now ready to reassemble the musket.


STEP 10: Buttplate
Once the stock has been completely oiled and wiped down, locate your buttplate and wood screws
and attach them to the stock. As these are wood screws it is important NOT to overtighten them
as they will strip out the wood. However, if it is already stripped you can purchase stainable
wood putty to remedy this. Please follow the instructions of the wood putty product!

STEP 11: Trigger Guard Assembly
Turn the stock over and locate the trigger guard assembly well. Gently insert your trigger guard
assembly, sling swivel to the front, into the well. Then screw the wood screws into the stock.
Again, if the wood has been stripped, you should use a wood putty so that the trigger guard
plate is securely fastened to the stock. Do not overtighten the screws.

STEP 12: Ramrod Spring
Turn the stock over again and locate the ramrod spoon well in the barrel channel. Place the
ramrod spoon, ensuring the groove in the front lines up with the pin hole and insert the pin.
Lightly tap the pin until it secures the spoon and is flush with the stock.

STEP 13: Lockplate
At this point we accelerate the ‘reverse order’ reassembly by installing the lockplate
BEFORE the barrel. As the linseed oil may have caused the stock to swell, it is simpler to
install the lockplate before the barrel due to the tight tolerances found on most EuroArms and Pedersoli
models. Locate the lockplate assembly, lockplate screws and side plate. Gently insert the l
ockplate while, at the same time, pushing the trigger forward so that the lockplate is fully seated.

Turn the stock over, insert the side plate into the wood and then tighten down the lockplate screws.
DO NOT OVERTIGHTEN the screws as the wood will expand and contract and overtightened
screws will prevent it from doing so, leading to cracks in the wood around the screws.

Once assembled, perform a functions check on your musket by pulling the hammer back to the
‘safe’ position and then pull on the trigger. The hammer should not fall forward. Pull the hammer
back to the ‘fire’ position and pull the trigger. The hammer should fall.

STEP 14: Barrel Band Springs
Take your barrel band springs and place them next to the corresponding positions of the stock.
Make sure the longest pin is to the rear (due to the width of the stock) and then second longest in
the middle. The front barrel and shortest to the front. Gently insert the barrel band springs into
the holes until the band springs are flush with the wood of the stock.

Loose Band Springs – A common issue is a loose band which slides up and down on the stock.
A simple fix is seen below, as you bend the long part of the band spring upward, bowing the metal
away from the stock. DO NOT TOUCH THE PIN, this will easily snap off necessitating its replacement.
If you do not wish to mar the metal surface, use a piece of old leather or cloth so the pliers do not
dig into the surface of the band spring.

STEP 15: Percussion Cone
Locate your cone and, with a very light amount of Ballistol on the threads, screw the cone into the barrel.
To prevent the nipple from seizing into the barrel and resulting in an expensive repair, remove the cone
often and clean out the bolster to prevent the black powder from corroding the threads.

STEP 16: Barrel & Barrel Bands
Place the barrel into the stock and line up the tang hole (located to the rear of the barrel)
with the receiving hole of the stock. Place a very light amount of ballistol on the tang screw
threads and screw the tang screw into the barrel until tight.

Slide the lower band onto the barrel and stock and slide it to the rear until the barrel band clicks into place.
If needed, bend the barrel band springs as mentioned previously to ensure a solid fit. Do the same with
the middle band. The front barrel band slips onto a pin in the front band spring. This will also click
into place securing the front band to the musket.

STEP 17: Ramrod
Slide your ramrod into the musket. Your musket is now clean and ready for your next event!
