Hard, brittle creosote deposits are removed from a chimney flue by striking the sharp ends of rods of flue cleaning apparatus against the deposits with penetrating impact and creosote chip-producing effect so as to break away creosote adhering to the flue. The chimney flue cleaning apparatus includes a cleaning head which comprises an elongated body, tapered from one end to the other, a plurality of metal rods fixed to the body and extending laterally therefrom, and a flexible bail having ends secured to intermediate portions within the body.
