Bar oil soaked military canvas bag

[Outpost75]

WW2 laundering practice did not use modern detergents, but only soap, similar to shaved Fels Naptha, Calgon or Ivory flakes and hot water, aided by scrub brush and plain scouring powder similar to BonAmi, being feldspar-based, not pumice. Mildew, flame retardant and insect resistant treatment would be renewed after laundering.

Treatment for so-called Army Duck was a commercial product which rendered the fabric waterproof, flame retardant, insect and mildew resistant. Not sure what was in it, but you can buy it in farm and building supply stores and there should be either a Mil-Spec or NFPA standard to identify it. I got mine at Tractor Supply.

I don't know why I remember but our Army field jackets (possibly more items) were Quarpel treated. That might be what was used.

Oil the rest of the bag so it all matches, blot up any excess and call it Good. Oil Cloth uses Boiled Linseed Oil but you've already started with bar oil and it's probably safer than Linseed.

I would take the bag add 1/2 gallon of diesel fuel into it then use it to start a brush pile on fire. Then buy the chainsaw plastic case to store it in and forget about it.

I clean my shot gun mop with dawn and they come out looking new

I'd say after the saw dust some fast evaporating solvent and saturate then wipe then saturate and add some dawn while still wet to get it in and start breaking up the oil. I believe stihl bar oil has detergent in it to thicken it up by the strands in it, kinda like mixing diesel and detergent.

+1 for Simple Green concentrate.
Dawn is great stuff until you get it in the washing machine.
Old old joke is to put Dawn in a dishwasher. Funny! Once.
Soak the bag for a few days in warm Simple Green, rinse lather repeat.
Fuel oil stinks, will make a washing machine stink forever.
A couple loads with hot water and Simple Green
now it smells like Simple Green...
I presoaked oily work clothes in Simple Green.
I convinced a boss to buy a 55 gallon drum of Simple Green concentrate,
We used it for degreaser and clothes, great stuff, cheap solvent!
Unlike Trich it's legal to dump it down the drain.
Almost edible, it won't destroy skin like hydrocarbon solvents.
Avoid the prediluted Simple Green it's expensive...
