Just cause you shoot it twice a month doesn't mean anything. Oxygen is always around it, and will always be working to oxidize and cause surface rust. If you lived in a damp enough environment, it could have orange powder on the barrel literally over night. I've had it happen in Ohio (and coastal North Carolina, when I was in the service) plenty of times. I spray my weapons down after every time I shoot them, even if I don't clean them after every trip to the range.
Hoppes is fine, make sure your patch runs through dry once your satisfied with yor cleaning.
Skip the Remoil wipes, and just buy a spray can of Remoil, and use patches in conjunction will it. Even spray some down the barrel when you store it, as well as use a wet patch and wipe the gun down with it, leaving as light or heavy a film as you want to. And do it more often. It will not hurt anything, and will only stand to prevent surface rust. It even helps wood gun stocks if you have those.
