We Say
When it comes to properly cleaning the exterior of a vehicle, there are always areas that a wash mitt simply cannot reach. Badges, grilles, intricate wheel designs, rubber seals and the edges of exterior trim can all collect dirt that requires a little more focused attention. A good detailing brush is therefore an essential part of any comprehensive wash routine, but not every surface benefits from the same type of bristle.
The Koch-Chemie Exterior Brush Set addresses this problem with four purpose-designed brushes, each featuring a different bristle specification and a colour-coded handle to identify its intended application. Rather than expecting one brush to handle everything from dirty wheels to delicate gloss black trim, the set provides the appropriate tool for each task.
Starting with the red brush, Koch-Chemie uses acid-resistant bristles specifically intended for wheel cleaning. This is useful when working with dedicated wheel cleaners, particularly around intricate spokes, wheel bolts and other areas where a larger wheel brush struggles to reach. The orange brush has a more robust construction for tougher cleaning jobs on exterior plastics, making it particularly useful around radiator grilles, lower trim and door sills.
The yellow brush is intended for glass and rubber surfaces, including mirror housings and window seals. These areas often accumulate road film and ingrained dirt that can be difficult to remove with a microfibre cloth alone. Having a dedicated brush makes it easier to work a suitable cleaner into tight gaps without unnecessarily disturbing adjacent surfaces.
Perhaps the most interesting of the four is the green brush. This features particularly fine bristles intended for delicate exterior surfaces such as chrome and piano black trim. These finishes are notoriously easy to mark, so the softer bristle construction is a sensible addition. Even so, we'd always recommend using plenty of lubrication, applying minimal pressure and testing sensitive surfaces before cleaning.
Another clever detail is the removable angled section incorporated into the brushes. This allows you to alter the brush configuration to improve access when cleaning awkward areas, making the set more adaptable than a conventional fixed-handle detailing brush.
We also particularly like the colour coding. Keeping separate brushes for wheels, plastics and sensitive finishes is good detailing practice, as it reduces the possibility of carrying abrasive contamination from heavily soiled areas onto more delicate surfaces. Of course, the brushes still need to be cleaned thoroughly after each use, but the system makes it much easier to maintain that separation.
For us, the Exterior Brush Set is a well-thought-out collection of detailing tools that addresses a genuine problem. Different exterior surfaces require different levels of agitation, and having four purpose-specific brushes makes cleaning more controlled and efficient. It's a practical investment for anyone who takes their exterior detailing seriously.

How To Use
1) Select the appropriate brush:
Choose the brush best suited to the surface being cleaned. Use red for wheels, orange for robust exterior plastics, yellow for glass and rubber, and green for more delicate exterior finishes.
2) Pre-rinse the area:
Rinse away loose dirt and contamination before introducing mechanical agitation. This is particularly important when cleaning delicate finishes that could be scratched by trapped grit.
3) Apply a suitable cleaner:
Apply an appropriate cleaning product to the surface or brush, following the chemical manufacturer's instructions. Use a dedicated wheel cleaner for wheels or a suitable all-purpose cleaner for exterior plastics and trim.
4) Agitate gently:
Work the brush over the surface using light, controlled movements. Koch-Chemie recommends applying even pressure without excessive force. Allow the bristles and cleaning solution to loosen contamination rather than relying on aggressive scrubbing.
5) Adjust the brush where required:
Where necessary, unscrew the angled section to improve access to awkward areas and intricate exterior components.
6) Rinse thoroughly:
Once the contamination has been loosened, rinse the area thoroughly with clean water to remove any remaining cleaning solution and dirt.
Care Instructions:
✓ Rinse brushes thoroughly with clean water after use
✓ Remove trapped contamination from the bristles
✓ Allow brushes to dry naturally before storage
✓ Keep wheel brushes separate from delicate paintwork brushes
✓ Avoid excessive pressure, particularly on sensitive finishes
✓ Always test the green brush on delicate surfaces before use
Important: Although the green brush has particularly fine bristles, this does not guarantee scratch-free cleaning on every sensitive surface. Always ensure the brush and surface are free from abrasive contamination, use suitable lubrication and test an inconspicuous area first.
