Yes, I know this has been discussed recently but I'm still perplexed. I have a .54 plains style rifle made in 1977 with a Douglas XX barrel. I've only owned the rifle for about 6 months and I have not shot it a lot.
After I clean the rifle I continue to get brown streaking on my patches, even days after I have cleaned the rifle with warm soapy water and patches with Cleanbore Oil and dry patches. I presume this is what is referred to as "flash" rust. I'm not so concerned with what starts it but I would like to know how to kill it, once and for all. Let's keep it simple. I have some Ballistol on the way.
Many thanks,

First. Black powder or substitutes?
Do you finish with a lightly oiled patch?, do you make sure the powder channels in the breech are oiled? Do you actually flush the bore or just wet it?
Soap is corrosive. It must be flushed out with clean water that is no more than tepid.
The bore once cleaned is completely unprotected and will oxidize even as you dry it.
Black iron oxide on the dying patches is very common. If you allow these black patches to air dry they often revert to red iron oxide and turn the patch tan or brown in an hour or two. Powder fouling turns black or in low humidity grey.
A tan patch at followup is not world shaking.
Red ugly rust on a follow up patch is.
The slight amount of rust on a tan colored patch could be left over oxide from cleaning.
Not using water to clean.
This is possible. But risky.
BP fouling dissolves rapidly in water and the water carries away the elements that promote corrosion.
Water and oil mixes.
Water and water soluble oil has been used and I first heard of it in the 1970s. "Moose Milk" or some such. I also heard the reports of significant after rust so I never used it.
The old Sharps Rifle Company recommended nothing but Sperm Whale Oil. But these were breech loaders and cleaned up far easier than a ML with a plug at the breech. A lot of the fouling was in the cartridge case. But the oil did not address the chlorate primer issue either. This requires water to remove.
If you use corrosive substitutes all bets are off.
From the Ballistol MSDS
*******
TECHNICAL DATA SHEETS FOR BALLISTOL
Contents Ballistol contains medicinal grade mineral oil, alkaline salts of oleic acid, several alcohols, Benzyl Acetate and an oil from vegetal seeds. The mineral oil is unchlorinated and conforms to the specifications of US Pharmacopeia XX.

Note. If this stuff is used over perchlorate fouling expect serious rust if the fouling is not removed in minutes.
All Alcohols have some water in them. Original Hoppes #9 for example simply activates perchlorate fouling. It also contains alcohol.
In any case I do not consider any "oil" with alcohol in it a preservative no matter what the label says. And its not trustworthy as a cleaner IMO either. Not for BP or perchlorate fouling.
In any case 0w30 motor oil will probably work as well or probably better since motor oils have additive package that among other things is designed to fight corrosion.
