The set consists of four brushes with an angle that can be unscrewed to reach even hard-to-reach places. The different bristles make it easy to clean different areas of outdoor use. The colour coding of the four brushes makes it easy to differentiate them according to the area of application. The acid-resistant red brush is ideal for cleaning the rims. The orange brush is the right choice for rough work on plastic parts, such as cleaning the radiator grille or sills. Glass surfaces and rubber, such as side mirrors or seals, can be effectively cleaned with the yellow brush. With particularly fine work on sensitive paint surfaces, such as chrome or piano lacquer, our green brush works with the necessary caution due to its particularly fine bristles. External cleaning is easy especially in combination with our products.
