That old timer who told me to stop using wire brushes on clay flues
I used to always scrub clay flue liners with a standard wire brush. Old guy named Charlie told me I was scratching the glaze off. Switched to poly brushes after that. Has anyone else had early work come back to bite them years later?

Oh man, you're talking about Charlie? He told me the exact same thing back in '08 and I thought he was just being dramatic. Sure enough, I had to go back and replace a liner three years later because the scratches turned into cracks and the whole thing was shot.
