One bottle of oven cleaner applied. No real noticeable difference although hard to tell as they are now wet.
Maybe a wire brush drill bit and COVID tent is the way to go!
I’m imagining this is about 250 years of carbon build up as this is the age of the house.
Maybe I should just install a grandfather clock there...
