This 150mm spark plug brush is a handheld cleaning tool designed to remove carbon, oil and light corrosion from spark plug electrodes and threads, restoring contact surfaces and helping maintain reliable ignition. It is primarily used during routine engine servicing, tune-ups and troubleshooting to clean spark plugs on cars, motorcycles, lawnmowers and small petrol engines.

The brush features a 150 mm overall length with a compact, round brush head sized to fit into the spark plug recess. The bristles are tempered high‑carbon steel for effective scraping of stubborn deposits while retaining spring and shape; the steel shaft is chrome‑plated for corrosion resistance and the handle is moulded polypropylene with a non‑slip grip for positive manual control. As a manual hand tool there are no threads, drives or head types to fit — the unit is a fixed head, hand‑held wire brush. It is produced in facilities operating to ISO 9001 quality management systems and is manufactured to Draper Tools’ hand tool quality checks to ensure consistent bristle retention and build integrity.

Typical applications include cleaning fouled plugs prior to gap checking, removing carbon build‑up from electrodes and thread relief to improve sealing, and light surface preparation of the plug seating area. Industries and users who commonly use the tool include automotive workshops, motorcycle and small‑engine repair centres, agricultural machinery maintenance, motorsport pits and DIY enthusiasts performing routine engine maintenance.

Key benefits of this 150 mm spark plug brush are its effective removal of deposits without damaging most plug electrodes, a corrosion‑resistant chrome shaft that prolongs service life in workshop environments, and a compact head profile that reaches into recessed spark plug wells. The tempered steel bristles deliver stiffness and durability appropriate for steel and nickel electrodes; for sensitive precious‑metal plugs (platinum/iridium) a softer brass or nylon brush is recommended to avoid abrasion.

Duchy Fasteners stocks this spark plug brush in single items and multi‑pack formats and carries related brushes in different head styles and materials to suit a range of plug types and applications. Sizes and pack quantities are available on request.
