Just to make shure I said it correctly, the idea of blowing baking soda (PH+) in the chimney isn't for cleaning it but to try to coat it with a basic product. Baking soda is a dry product and doesn't adhere very well on the vertical chimneys wall, if it could be blowed just ""semi"" dry it could be more efficient.
Anyways, before finding the perfect solution, I preffer to try something than nothing. :)

Cracked tiles are a non-issue with coal, interior or exterior. The cracks mean nothing unless the tile stack has cracked to pieces and is collapsing - such as from an earthquake, intentional demolition, or a faulty (completely unvitrified) liner installed low in the tile stack. Stack is under negative pressure along it's length. A few cracks in an otherwise intact tile stack (hint - one or two vertical cracks - they were probably installed that way) is barely an issue /w a wood stove and irrelevant with coal.

The "chimney professionals" who see a crack or two in a tile liner and claim it's "unsafe" now with the for-profit backing of the CSIA et al. need to be taken out and smacked around; If you don't know how a chimney works or understand your trade - get the HELL OUT :mad:

That cap didn't look too bad; there's not much actual corrosion on that one. Coal attacks stainless four ways - very low o2 in flue gasses prevent replacment of passivation layer, Chlorine/HCL attack (coals contain significant chlorine), Sulfur/acid attack, and perhaps most importantly, what allows all these things to come together and work rapidly, is iron pitting corrosion from the iron in the coal fly ash.

If it was possible to replace a SS insulated chimney with a masonery one , it would be so nice to be able to do so. NO MORE RUST :cry: .
But in my personnal case, I think that is just a dream :!:
