Even the smell of Hoppes 9 can take you back to the old days!To me, cleaning a gun brings back childhood memories (Am I the only one that feels this way?)
Sidenote: one thing I thought of the other day is if I wasn't home and someone broke into my house, that person would know where my main firearm stash is just by the smell of Hoppes. I gotta think of a way to mask the smell.
Back to your post: For me, my only quirk is that I like to brush the barrel in one direction. I've had a bunch of discussions with people regarding this, and they swear that brushing backwards won't mess up the rifling of the barrel. Call me superstitious, but I still brush one way when cleaning my handguns.
