Cleaning your cast iron store is not a difficult task. This is a guide about cleaning a cast iron wood stove.
I have a cast iron woodstove (Vermont castings) and I had a leaky roof that dripped water onto the top of the stove. How do I clean the rust off without damaging the black cast iron?
Take ordinary bacon grease on a newspaper and wipe the rust off. We do this yearly to clean up our wood stove and to make it shiny.
