Brian: The pistol isn't all that dirty. I run mine with a load of dishes and put the dishes away after the cycle. A close examination of the dishes won't show a thing. However, in response to part of your question, the pistol should be cleaned after every firing. I've never stripped my 1860 blued colt replica beyond taking off the handles and separating the weapon into barrel, cylinder and frame. I've had it for about 10 years now and shoot it a lot. graybeard
