    I had a little surface rust inside my Jotul F500 after the long summer just sitting there but nothing out of the ordinary. Whats up with yours?

    It's a little around the doghouse and the left/loader door...on the door. Looking at some of these pictures of various stoves...it looks as tho... alot of them have the issue including steel? I figured that I had better ask. I wonder...if because they sit quite a bit right now...that might be happening.

    I use gun cleaning solvent and gun oil to keep mine from rusting. Hoppe's #9 does a great job removing surface rust and a good spray down with rem-oil once or twice over the non-burning season will prevent any rust from developing. Make sure you wipe it off well before burning (it is flammable), and be ready for a little smoke while the remnants of the coating burn off.

    I appreciate that...but should not have to worry about it now that the season is starting again?

    I stored my 1985 VC Cast Iron stove in the basement for 4 years - just sold it yesterday and it had no rust.
    I wonder if the older grade of steel was better?

    Fire man...when you say steel...that I'm assuming is not cast iron... I'm thinking cast iron is more susceptible to rust? Even tho...it's really the same material...just a different way it's formed? I know I've had many offset smokers that rust and I mean 1/4 inch steel.

    My stove was cast iron. I should have said the iron back then was better. I'm not sure which one rusts easier. It sure surprised me how rust-free that stove was.

    No more or less humid than other places . . . I do try to clean the firebox out come Spring time (forgot to do so this year) and in the past have also placed a box of baking soda inside or run a candle in the summer when I could smell the creosote smell . . . maybe I just burn the rust off every year with my fires. ;)

    So leaving ash in there for the non burn periods is a bad thing?
