- STIFF POLYPROPYLENE BRISTLES FOR DEEP CLEANING – Rigid poly bristles effectively scrub coal, soot, and creosote deposits from metal stove pipes, flue liners, and chimneys. Bristles maintain their shape through repeated use, unlike wire brushes that can shed and damage flue walls.
- HEAVY-DUTY GALVANIZED STEEL DOUBLE-SPIRAL STEM – The precision-wound stem resists rust and corrosion while delivering consistent rotational force to the brush head. Engineered for manual sweeping — will not break down like wire-core alternatives under repeated flexion.
- UNIVERSAL 1/4" NPSM MALE PIPE THREAD FITTING – Compatible with Midwest Hearth's 18-foot fiberglass rod extension kit (sold separately, B-ASIN link below) and most standard chimney rod systems. Fits 8-inch round flue openings — measure your inner flue diameter before ordering.
- AVAILABLE IN 3 SIZES — ORDER THE RIGHT FIT – Choose 6", 7", or 8" Round to match your flue's inner diameter. For best results, select a brush that matches your flue size exactly. Designed for use in masonry and metal stove pipe flues — not recommended for use with power drills or rotary tools.
- PROFESSIONAL QUALITY, MADE IN THE USA – Manufactured in the Midwest by Midwest Hearth, a trusted small business brand with thousands of verified reviews. Meets professional chimney sweep standards. Chimneys should be cleaned annually — more frequently with heavy fireplace use.
