Here's a picture of mine taken from the SE looking NW...............pretty darn clean IMHO!!! What are we now 3/5ths thru the burning season??? Prevailing winds are usually westerish around here, so this'd be the dirty side. Look much better than the first few years of burning until I got 3 years ahead on wood. Thanks again BWS!!!!!!
I had the chimney cleaned summer '22. Been burning since October. Steady burning since November. Stack cap is looking just fine this morning.
