A friend brought this smith and wesson 686 over and asked what to use to clean it. I have never seen a stainless steel revolver rust like this one. He hasn't fired in over a year. I go shoot every other month but he has been too busy with work to come along. Anyway, any Ideas what to use to get the rust off. I've tried baking soda on a moistened steel wool and break free. I've removed quite a bit but have a long way to go. Any ideas on product or procedure to get it all off?
Thanks!smith 357.jpg
