Hey ya'll thanks for helping out. Last year at the end of the season, I cleaned out the pellet stove, removed extra pellets, cleaned her out, and left some ash in the tray to help absorb moisture over the summer.

Got around today to sweeping the exhaust liner and wanted to start it up quick to check it out (still in high 70s here). She started great, but I realized the entire inside is covered in spots of dark orange rust...

The thing is old, so I'm not interested in taking it apart and painting it. It was rusty before. But there is so much in there that I can't even get the trap door to open and close to empty the burn pot!

I want to fix this now, and also prevent it in the future. At the end of the year, could I try spraying the inside with an oil, like a simple vegetable oil? I dont want to make things worst by gunking up or ruining any components. As for now... could I try spraying vegetable oil inside the burn pot, on the trap door, to try and help smooth it out? It worked like a dream before the summer.

Thanks everyone

That’s pretty normal, as ling as the rust isn’t deep, just fire it up and don’t worry about it

Cool :) Just wanted to make sure. I'm sure the fire will burn it off quick.

Wanted to add: I took off a plate and was able to gain access to the swiveling piece that connects the trap door to the pull rod. Looks like that just got a bit rusty and seized up. Sprayed with WD40 and let soak a few minutes, then sprayed some Silicone lubricant and it's moving freely again.

Thanks

Get yourself a pressurized can of Stabil Fogging oil and spray it down when you do the final clean in the spring. Been using that stuff right along on mine. Corn is extremely corrosive and the fogging oil has saved the inside of mine for 15 years now. TSC (Tractor Supply) has it all the time.
