The K2 Detailing Brush M325 Strong is an extra stiff cleaning brush developed for technical cleaning tasks where maximum cleaning power is required. With a working diameter of 30 mm and a total length of 28 cm, the brush reaches deep into hard-to-access areas without the operator's hand coming into contact with dirt or aggressive chemicals.

The Strong bristle retains its stiffness even under heavy pressure and is unaffected by strong APC or degreasers. This makes the brush a reliable tool for daily use in professional environments. See more K2 detailing products in our range.

The long handle provides a secure grip and keeps the hand away from chemicals and ingrained dirt – a feature that professional detailers and vehicle preparation technicians particularly appreciate when working on engine bays and underbodies.

What is the K2 Detailing Brush M325 Strong and why choose it?

The K2 M325 Strong is a specialist detailing brush designed for situations where standard brushes with softer bristles are not sufficient. The extra stiff bristle effectively penetrates baked-on deposits, old grease, and road grime lodged in engine bays, wheel arches, and suspension components. Unlike softer detailing brushes, the M325 Strong is not intended for painted surfaces – it is built for technical surfaces where cleaning efficiency takes priority over surface protection.

The combination of a large working diameter (30 mm) and a long handle (28 cm) allows large areas to be covered quickly whilst still reaching deep into narrow spaces. It is a practical choice for vehicle preparation workshops and detailing studios working on vehicles in poor condition that require a tool capable of maintaining pace without compromising results.
