After shooting my SA20, I find a ring of hardened crud on the magazine tube. It takes a considerable amount of effort to get rid of this, even when using Hoppe's #9 or Powderblast spray. I end up scrubbing for quite a while to get this off.
I also get a similar coating on the piston that takes forever to get off. I usually end up leaving the piston soaking in Hoppe's overnight to get rid of it.
After cleaning, I wipe down the piston with a CLP soaked rag, so it is wet when then gun is fired.\
What do you guys do? Do you run the gun with the piston dry or wet? What do you use to clean it with?
