Our Oslo develops a whitish-grey haze on the glass every single day. By the end of each day, there's a tombstone-shaped area on the glass that makes the fire appear hazy. Around the edges, the glass is perfectly clear. There's no brown or black in the haze, and it wipes off easily with a damp paper towel when the stove is cool. Our wood has been split and stacked in the sun for 3 - 5 years, and it burns easily and without any smoke from the chimney. We run our stove hot when it's burning, and we never use it for overnight burns.

I've read here that some folks are able to clean their glass once a week or every two weeks. Are there any tips for reducing the amount of haze buildup each day? It's not a major problem -- just a minor inconvenience. Thanks.
 
My liberty does the same thing. The entire glass gets covered in a white haze and it drives me crazy. I know its not the wood because its bone dry and my glass never turns black. I think it has something to do with the air wash because when I run my stove with the air control half way open I get not white haze. I usually clean my glass with a wet paper towel every morning when the stove top is 200 degrees before I reload.
 
Same here - I clean the glass once every few weeks, then just let the haze slowly build up again. Just a part of the burning process - best to just not worry too much about it. Of course, watching the fire through perfect glass is awesome, so I can see why you'd like to keep it that way! Cheers!
 
Are you sure that your ashpan is sealed up tight? Check your door gaskets as well. If you have air leaking, it can interrupt the airwash process. The only time my stoves get dirty glass is when I turn them way down, it simply cleans itself when I get a hot fire going again.
 
I have been getting that latley also..did not last season.
But last season it was more brown and black crap..but way less of that this season.
I'm thinking the white/gray haze is a step up..lol.
 
I also get a white gray haze on my glass when burning at lower temps. With a good hot fire mine cleans up.
 
Thanks for the responses. I'll check the ashpan seal. It has never been tight enough to grip a dollar bill, even after replacing the gasket. The ashpan door gasket just presses against a flat surface on the stove -- there's no tongue and groove fit like around the other doors. I'm not sure I know how to get it tighter. I checked two new Oslo stoves in dealer showrooms, and they both let dollar bills slip out of the ash pan door.
 
Our stove has a light haze when burning 24/7. It's not enough to block the fire view, but somewhat noticeable. I clean it when I dump ashes. Just did it this morning. No biggee.
 
Mines doin the same thing now that the temps finally got to below 0. Clear around the rim of the glass and kinda fogged in the middle. I aint worried bout it cuz I'm thinkin it's steam. Thats all I see commin outta the chimney too in these temps.

If you don't pass the dollar bill test you need to make some adjustments, I can't remember exactly how to adjust the handles on the Oslo, I'm sure someone on here can tell you how.
 
Once upon a time I was obsessive on clean glass.

Then I got to the point I was less obsessive, knowing the hazy glass would return soon after cleaning.

This season so far I think I've cleaned the glass 3 times.

Maybe next year I won't clean it at all.

You should clean the glass every so often. If I remember correctly when reading through my manual for the f600 there was a statement in there that not cleaning the glass could lead to a permanent staining in the glass.

I clean mine very other week.
 
I get the same haze in the same place. I'm assuming if it is not black or brown, it is fine.
 
look on the bright side... haze is better to look at than dog sh!t. Could be a lot worse. :)
 
It sounds like others get frequent haze, too. As long as what I'm seeing is somewhat typical for the Oslo, it's not a problem -- other than clean glass is nicer to look through. If other Oslo stoves typically don't build up haze for several days, then I'd be wondering what I was doing wrong.

Thanks for the comments.

Maybe leaking gaskets play a role in this.

I have the exact same situation. I just clean the glass when the stove is cool (which might happen once a month in the winter).
