Long Flexible Drain Brush Set

10 individually packaged flexible drain brushes built for accessing and clearing obstructions in narrow, contoured drainage pathways. Each brush is 45 cm long, with a 30 cm fully articulating steel-wire shaft encased in hard-wearing POM plastic. A compact tubular brush head (6 mm OD, 2 cm long) features densely packed, rotating nylon filaments. Total unit mass: ~12 g. Material selection prioritises mechanical reliability: POM withstands repeated bending without creep; steel wire resists permanent deformation under compression; nylon remains supple and unbroken after exposure to road salt, coolant residues, and mild detergents. The brush head cleans via gentle rotational friction — loosening particulate matter without scraping — while the hand ring enables precise feed-and-pull motion. No batteries, no power source: purely mechanical, intuitive operation suitable for DIY users and professional detailers alike. Primary applications include sunroof drain channels (front/rear), door bottom weep holes, fuel cap vent lines, skylight perimeter drains, refrigerator defrost tubing, aquarium airline connectors, and small-bore filter housings. Proven effective against biological growth, mineral deposits, and fibrous debris in both vertical and horizontal orientations.
