Clean it after you're done shooting it, ya dingus. Doesn't have to be right after, it can wait until you get home and put your shit away. Just make sure that you clean it that day with a water-based cleaning product. And yes, water itself works just fine if you can manage your autism and not be a retard about it. And here's a fun fact that you probably don't know, as this is not a story that the jedi would tell you:
>most of those old black powder guns that got "rusted out by black powder," actually got rusted out in the early days of smokeless, with smokeless ammo
>the smokeless powders of the day were advertised as not needing water to clean, which was technically correct, but no one considered that the primers might be corrosive
>nobody noticed that chlorate primers might destroy a bore during the black powder days because they were cleaning their guns promptly with water to deal with black powder fouling, which is also exactly how one deals with chlorate salts
>suddenly bores start rotting out and everyone from the ammo manufacturers to the us ordnance board were trying to figure out what was happening
>all sorts of crazy theories about acids getting deposited in metal and stupid shit like that
>it took the industry a decade or so to figure out that it was chlorate salt deposits from the primers that was the cause, and water was the cure
