Thought the chimney brush whip was overkill until the 1890s brick house on Elm St
Bought the 6 foot flexible whip after a sweep in Dayton told me rods alone were tearing up his old mortar, and after two flues on that soft 1890s brick I could see the difference in how the joints held up, so now I want to know what you all run on really old soft brick.

What kind of shape are the mortar joints in before you even start brushing? I ask because with 1890s brick around here the lime mortar is usually so soft you can carve it with a fingernail, and even a poly whip at low speed will knock the face off it. Do you run the whip on a drill or by hand? On the really crumbly stuff I have had better luck doing most of the work by hand with a poly brush and only using the drill whip on the hard soot up top. Curious if you changed your speed too, because slowing down made more of a difference than switching from rods on the last soft flue I did.
