How is the best way to clean the rust out of the inside of a fire box. I have been using a wire brush but just can’t seem to get back down to shiny metal again so I can get it oiled down.

How long are you leaving ashes in the firebox? Ashes will draw moisture and cause rust. I clean the ashes out of my firebox as soon as they are cool enough to remove and I don't have any rust on the INSIDE. The outside is rusty, but that's a constant battle. An angle grinder with a wire wheel will make quick work of the rust and will probably be easier to use on the inside as opposed to a drill motor and wire wheel.How is the best way to clean the rust out of the inside of a fire box.
