I have been scrubbing and scrubbing my rifle rifle for days with military grade solvent and it refuses to get clean.
That is some eldritch tire fouling.

@Doomguy666: it's best to clean a rifle after every use. Store the rifle in a low humid spot. Get dehumidifier packs if needed (or a safe) and it should be ok. Safes are pricey, but if you have just the one rifle, then it should be fine in a case.

@Doomguy666: I use Remington all purpose gun cleaner, then I wipe it down and use gun oil when needed. There's also cleaning patches and brushes if needed for cleanings. If rust is present you may need steel wool.
