I use Hoppes to scrub the bore. It does a good job. There are other products that do just as good a job but Hoppes is readily available and pretty cheap. I run a patch of plain gun oil down the bore after scrubbing. I use an ammonia based product for copper fouling. Over the years I have tried several of the new and improved cleaner/lubricants. They work well but are expensive. Gun cleaning is pretty simple. All you are doing is removing the powder fouling and applying a film of oil to keep it from rusting. It doesn't take much to accomplish this. I have never had any problems with this approach.
