When I used Windex and Vinegar mix, I bought it off the store-shelf already mixed in a spray bottle. Just spray it on a couple of soft cotton patches and run them thru the barrel, then a dry patch, then an oily one. I now use another brand of cleaner.
Leaving guns loaded over-night is a personal choice. My experience, though limited, leads me to think it's not for me. I use pellets in my ML and it's real simple to drop-out the plug and push it all out.
Oh yeah, welcome to a very fun sport :lol: :lol: :lol: .
