Cleaning Kit Flintlock How Would You Clean A Gun Without A Cleaning Kit?

How would you clean a gun without a cleaning kit? - cleaning kit flintlock

I have a friend who is thinking about something before a child very seriously and responsibly. No way his grandmother got rid of certain things (which the Second World War, and I believe his grandparents who have died), and had been found in any case, my friend, an old Springfield rifle and Colt. 45, he wanted to hold out. So, any secret with me to the end (I do not know how he did it because I get into the car just their parents) and the long story short, he wanted to help some good weapons. Levels is in a closed box for your information. And in fact, his parents are a bit like this again no weapons in the house.

Then I will come to the point: How can my friend clean the barrels of powder, which already corrode (probably not) the course of gu mayns without a cleaning kit? Obviously you can not use a cleaning kit, without being discovered.
