Hi,

What are all of your thoughts on the Birchwood Casey Super Strength 2 in one Bore cleaner. I use it sometimes on my guns and i used it once on my Garand where i left it in the barrell for a day to cut the copper fouling. I want to ask you if it is safe to leave it in my barrell for a day or so?
