Ashtrol
All it does is neutralize any acids that may be in the wood ash or clinkers, its pretty much just barn or plant lime. It keeps the firebox from rusting around the ash line which can happen when burning green wood.
When I got my CB, the dealer told me to rake the coals from one side and put one teaspoon along the wall to prevent rusting caused by the ash and the following day do the same thing to the other side and on the third day do the front.
Later in the day, he told me to save myself a few bucks and buy Barn Lime or Plant Lime. I used barn lime for the first year and now I picked up a bag of Garden Lime when it was on sale in the fall. It’s so cheap that I put a half cup along the sides and the front and leave in mixed in with the ash until I remove them. This Garden/ Plant Lime is very fine and it looks like Ashtrol, smells like Ashtrol and If you think about it, too much ash on your garden will raise the PH in the soil. So you put lime on the garden to lower the PH. :msp_ohmy:
Ashtrol has nothing to do with removing the creosote so don’t count on it for that.
