Anybody have fireplace here? I have an 80 year old brick fireplace that we use pretty regularly. I cleaned it today and decided I want to scrub the soot and creosote off the bricks... I used a little vinegar and water, which seemed to do a decent job at first, but I figure it's doing as well as just water would. I have 3 marble plates (for lack of a better word) that cover most of the fireplace floor, and they almost looked stained black, but I don't think that's the cae, and I almost think I'm kind of polishing that color in with the vinegar. The bricks just looked rinsed, not cleaned. Any chemicals or techniques y'all recommend? I'd like to clean the facing bricks, too, but I'm not that worried about them, they're not that bad.
