Why does nobody talk about creosote glaze vs regular soot until it's a chimney fire waiting to happen
Was chatting with a homeowner in Portland who said her old sweep told her the shiny black stuff was just "heavy soot" and to run a log once a week. That glaze is stage 3 creosote and it needs a rotary whip or chemical treatment, not a hot fire. How are you all explaining the difference to customers without scaring them off?
Had the same thing happen last winter, guy told me his sweep said the shiny stuff was nothing to worry about and just burn it hot. That glaze is basically tar and a hot fire just bakes it on harder, you need the whip or the chemical stuff to actually get it off. I just show customers a pic of stage 3 next to regular fluffy soot and tell them it's the difference between dust and dried glue.
Running a hot fire does help in some cases but only if it is done right after you notice the glaze, not after it has sat there all season. Once stage 3 has cured for months, heat just makes it harder and you are right about that part. The whip is still the safer bet for most folks though, since most people do not catch it early enough for the burn method to work.
