Hi All , Finished using my baseburner around 4 weeks ago .Gave it a complete clean Out no ash left anywhere , and used graphite polish on the cast iron body , mothers polish on the nickel , and cleaned the mica . Today I opened the front door and noticed a weird yellow rice type growth all over the coal magazine ! Wouldn’t have thought anything would grow on cast iron , it isn’t damp on the inside of the stove , so I am stumped as to what it is , where it came from , but more importantly the best way to get rid of it ! Wondered if any of you lads have had a similar experience and how you went about eradicating it . All suggestions appreciated.

Sulfur in the coal heated and condensing where it doesn't get hot enough to be burned off, or covered up with fly ash. I get the same up inside the top area of my Glenwood #6 magazine.

I ignore it because so far it hasn't built up after 2-1/2 seasons. Usually gone after running the stove really hot when our temps get below zero F.

How do I get rid of it ? Won’t be firing up the stove till winter ? Is there something you can spray on to get rid of it ?

You could spray it with a basic compound like baking soda or lye to neutralize

the acid.

Thanks for the advice , much to my wife’s dismay I have lit the stove this morning used a couple of kiln dried logs to start the fire 🔥 then used the last of my smokeless fuel and anthracite, going to let it burn at a high temp and see if that will get rid of it ! If not will do what you suggest . 👍( ps know I shouldn’t use logs in a baseburner but it is the first and last time ) .
