Just finished browning a barrel using Laurel Mountain and I have a beautiful smooth purplish brown finish. I’ve oiled for the last couple days and I continue to have pretty heavy rust stains on the rag. I did use baking soda to stop the reaction and carded lightly with a gray Scotchbrite pad. Should I get more aggressive with the pad or steel wool? I don’t want to ruin this beautiful finish. Thx
