Damp wood will make the glass dirty and lots of times a hot fire cleans it off.. You can dip a damp paper towel in the ashes and clean the glass off once cool then clean off with a clean damp paper towel.. I also use a special woodstove glass cleaner that I think I bought at Walmart.. I loaded the stove last night and it got to 81 in the house still 75 9 hrs. later and it was in the low 20's here last night.. Time to open a window ..Thanks everyone. I got 7 hours of sleep which means the stove went 7 hours. This morning there was still wood and a lot of hot coals. I piece of raybonz's wood and we are off again. Thanks again. As for the glass. I did throw in some damp stuff.
