I have done kind of the same with Kroil: Wet the bore good, wet it again the next day and then let it sit for another few days. The longer it sits, the better. Rinse and repeat as necessary.
I had an SVT-40 with an extremely nasty bore, no matter how hard I scrubbed it was still rough so I wrote it off as a hopeless case. Then somebody suggested that I spray some Kroil in it, so I did that, put up the rifle and forgot all about it. A few weeks later a friend comes buy and wants to buy it, so I sold it at a "bad bore price". A few days later he texted me and said that the crud wiped right out, the bore was a little corroded but the rifling was fine.
