    Kerosene to degrease brass?

    Howdy all,

    Did a quick search and didnít turn up anything specific on it. I usually use regular unleaded gasoline to degrease my brass after resizing but have a larger than normal amount of brass to degrease. Does kerosene (have a mostly full jerry can of it we have no use for) do a good job degreasing it?

    Seems to me that the kerosene would leave as much residue as the sizing lube you are trying to get rid of.

    I go about my case prep a bit differently, I size/deprime first, then tumble to clean so I never considered using volatile solvents in the process...

    NO!!! Kerosene is an oil, it works well to degrease engine parts but will leave an oily film that takes forever to dry and stinks even longer.
    Also it would probably kill any primers it comes in contact with.

    May I suggest citrus acid and hot water instead of kerosene ?

    Mineral Spirits is a pretty good degreaser and it will dry up completely. It is not as nasty and carcinogenic as gasoline.
    I also add it to my tumbling media to reduce dust and help clean the gunk of brass.
    Sent from my PC with a keyboard and camera on it with internet too.

    I personaly wouldn't.

    For petroleum / wax based lubes, I'd use something like prep-all that painters use to wipe down metal prior to painting.. if you don't you can get fisheyes.

    For a couple bucks cheaper.. straight naptha would work.

    Now.. if your lube is soap or water based.. then you could go with a mix of 90% isopropyl and a little naptha.

    Use all these out doors in good ventilation.

    Mineral Spirits also has oil in it..

    Not sure why you need a degreaser but Denatured Alcohol works well as does Acetone, neither leave any residue and they both evaporate pretty quick

    Kerosene is a light oil.

    Kerosene would probably leave undesirable residue behind. When I use a lube that soapy water won't remove I spray the cases with brake cleaner or electrical contact cleaner. Kerosene might cut the lube and then you could use hot soapy water.

    My opinion only. If you need gasoline or kerosene to remove the lube from your cases after sizing, then you are using too much lube or the wrong kind of lube.

    I use Imperial Sizing Wax and just give the brass a quick wipe with a cloth dampened with Windex or any other window cleaner. No to kerosene or gas.

    Thank you for the replies everyone. In the long term this is one I’m going to be trying out some different lines.

    Just doing it how I remember my dad doing it. Clean motor oil. Never heard of anyone else using it, and always just dealt with the degreasing as coming with the territory. Never did a batch as big as I’m currently doing and know their is probably a much better way of doing it. In the meantime I’ve got this one last batch to degrease and will hopefully find another method with easier cleanup once I do some research. Really enjoy having the forums search function and members to answer my questions.

    I've seen people use motor oil and transmission fluid, MMO, etc... there are just easier to clean up lubes presently available.

    GAS The test fluids selected for this investigation were Fuel C, CE10a, CE17a, and CE25a. Fuel C was
    selected as the control since it is representative of premium gasoline and is a standard test fluid widely
    used for studying material compatibility to gasoline. CE10a represents an aggressive formulation of E10,
    and as such, it can be viewed as a baseline test fuel since E10 is currently available in many, if not most,
    fuel dispensers. Dawn dish detergent contains as much as 5% Ethanol. Ethanol may cause stress crossion cracking.

    How was the test conducted? was there any humidity control? ethanol fuel mixtures have quite an affinity for water. Water in the soloution ( azeotrope ) will allow much much more corrosion to occur.

    Was there any method to prevent galvanic reaction? ( which would also hasten corrosion )

    Use TSP (Trisodium Phosphate aka Detergent) and water. You can get the pure stuff at Home Depot. Do Not use TSP substitute.
    It removes oil very well.

    No experience with it for cleaning brass, but acetone will remove a lot of things and evaporates away very quickly.

    Google it. I wanted to know what damage Ethanol would cause to fuel systems in old cars and old mowers. The photo was part of the study.

    if you could pass along the link you used to find it, it would be helpfull. just posting the info, then telling someone to 'google it'.. well.. that gets lumped into 98% of the rest of the 'truth' that turns up on the internet. Now.. if there is proof.. that's different.
