Don't know if you guys ready my comment on this stuff. But I ready where a couple of you were using it so when I was at the gun shop the other day, I grabbed a bottle of it to try. I was running low on #13 so I figured why not.
After my last session with the new 45 barrel and not being able to clean it right away, I ran a patch of T17 down the bore, both sides and didn't get of give it its bath until later.
When I was done the water was just as clean as when I put it in the container.
I probably didn't even have to wash that barrel out. That T17 removed all the powder residue with only one patch.
