I have the chimney pipe (connection between fireplace and chimney) not cleaned for years. In the look-up in the access panel, I was shocked by the thick Rußflusen and firmer deposits on the inner pipe walls. Therefore I have decided for the broom made of spring steel and have the cleaning performance very satisfied. The purpose matching 3 m flex rod is however still very stiff. Does the chimney pipe with 20 cm a 45 ° angle upwards towards the chimney. To get past this bend was somewhat hakelig and has the tube in this area not cleaned quite as good. As it once went back not before / I had the Flex rod overtighten in, then slid the broom through the twist again on. (The same principle as that of the spiral for the purification of the sewage pipe). Apparently also a matter of practice. All in all I am satisfied overall.
