We have a Drolet Blackcomb that is 5 yrs old. It has started to rust around the collar in the off season. Wonder what is causing that and can I use some rust converter on it and repaint it?
As long as it's high temp stove paint why not. I've rubbed some spots on my stove with vegetable oil.
This kind of stuff happens to woodstoves in the off-season, my Napoleon 1900P has the same issue, along with the single wall pipe that connects it to the Class A tee. I use Rutland stove polish and a piece of Scotch Pad on the rusted areas to clean and protect the metal, and it seems to work ok. You could also use hi-temp stove paint, but bear in mind that you'll have some odor upon the first fire-up come fall heating season. Others have used cooking spray (PAM, etc) to protect their stove from humidity rust, that's really good for the interior metal.
Yeah it seems a lot of people "fog" the insides of their stoves with some type of oil...for the outside, I'd say clean it up with some scotchbrite and then touch it up with stove paint. $4 at wallyworld https://www.walmart.com/ip/STA-BIL-...-Against-Rust-and-Corrosion-12-fl-oz/32926613
Might just be that your chimney is an opening to atmosphere, humidity and rain water.... In addition to the suggestions above for cleaning it up, you could remove that section of pipe for the non-heating season and cap off the stove and at the thimble...?
Watch out that no rain or condensate is dripping down. I discovered it from wet insulation and surface rust; even though the chimney was to specs, there is a small fastener that can let in rain. Serious problem . I also built a summer chimney cap which keeps everything dry and prevents stinkbugs. It's at the end of this thread (hope this works) Crown repair
