I use Very Hot soap and water to clean the barrel, and boiling water to flush the barrel and have never had flash rust. Of couse, I have leather gloves one, and once the barrel is flushed, I dry patch it and then run sheath through it. I've checked them later but never found even a hint of rust.Once the rifle is cool then I put the rifle back together and everythingstays just fine until the next time I shoot.
i was not to happy after using warm soapy water for 36 years in same t/chawkins andthen using HOT SOAPY WATER,i got rust,you could see it and it came out on patch when i dried it a few minutes later..
for 36 years, never had flash rust and used bore butter until now to store..no doubt in my mine that hot water causes this rust..
