Dawn and hot water to clean it up.
My kid bought me some Frog Lube, which I've been using on all my guns this year.
Not sure if Frog Lube works any better than the others, but it sure smells better.
Being primarily plant-based oil, be aware that the bore may get sticky between shots, unless you remove all of it prior to your first shot.
My buddy left traces of Frog Lube in the bore and struggled mightily trying to load sabot/bullets at the range.
