I still need to clean my firebox better, forgot. I have about an inch thick of creosote and ash that is as hard as a rock. Seems like the only way to remove it is hitting we it a hammer. Anyone have a better method? Hammer doesn't seem too good for the stove. Thanks

A lot of guys stuff it full of cardboard and lite it. It will ignite the creosote and burn it all off.
An inch thick?? What kind of wood are you burning? I've been running a 10,000E for 3 years and I'm oversized and I've not had a creosote problem at all. I was just going to burn mine off this summer just to see how well this method works. I barely have a film on mine.

You could try heating it up a little bit with a torch to make it softer and then scraping it off. Where it is built up at?
-
It's built up along the bottom third of firebox, some places more than others. Stove is oversized, was looking to heat more building s in the future. Also the ashes did not get stirred up enough so that is where it mainly built up along the sides. I'll give a torch a try. Burnt mainly oak seasoned one year and some boxelder.

I have the same problem, every other week I try to remove the creosote flaked stuff is easy. Mine is what they called glazed creosote it is like a thick gooey layer that can only be removed by high heat or some chemical. I know wet ash can cause a acid environment which can cause rusting. I researched for hours and cant find and relation with the chemical composition of creosote causing rust. If anything I think glazed creosote protects the metal. In my opinion it protects the fire box. Can anyone chime in on creosote glazed or not causing significant rusting?

My stove had the same thing thick creosote built up on the bottom and back. This summer I opened all the doors and power washed my stove out. Didn't take the thick build up out. I chipped it out with hammer. But like u said I kinda though that may not be good on the welds so I prolly won't in the future
-
I always have wondered too if leaving the thin glaze, would harm the metal. I scraped off the flaky stuff and leave the glaze.
-
I scrape my walls with a hoe type deal all season, and clean ashes regular, never had that kind of buildup. Also, beginning and end of season do the cardboard burn out. At the end of season, I remove all ashes.
Not sure if this is right. Just my third or fourth season of hesting with the boiler.

Here is how I clean mine out.

I would always save some extremely dry wood back or even use 2x4’s and burn it out, then I’d scrape the loose stuff off and leave the glaze, I never had firebox issues from the glaze and my original was mild steel.
-
The only thing I scrape on my E-Classic 1400 is all of the welds, I do not scrape the glaze from any of the surfaces. It takes long enough to scrape all of the weld surfaces. If I had to scrape all of the other surfaces, I'd still be working on it.
I kinda figure it'll be about another week or 2 and then I'll be burning wood until Spring. Roger
