Koch-Chemie Exterior Brush Set — Chemical-Resistant Exterior Detailing Brushes

Chemical-Resistant Professional Exterior Detailing Brushes

Koch-Chemie Exterior Brush Set includes four precision-sized detailing brushes designed specifically for cleaning intricate exterior automotive areas. Featuring chemical-resistant synthetic bristles set into completely metal-free poly-handles, these brushes withstand harsh alkaline pre-washes, bug removers, and wheel cleaners without softening, curling, or scratching delicate emblems and painted grilles.

Key Performance Advantages

• Completely Metal-Free Architecture: High-impact composite plastic ferrule and handle ensure zero scratching if accidental contact occurs.
• Chemical & Acid Resistant: Synthetic bristles resist curling and bristle fallout when exposed to wheel acids and alkaline TFR cleaners.
• Four Graduated Diameters: Covers every exterior crevice from narrow emblem surrounds to wide honeycomb radiator grilles.
• Ergonomic Balanced Grip: Textured handles provide comfortable tactile feedback during wet soapy cleaning sessions.

Recommended Application Protocol

1. Spray cleaning chemical (e.g., Green Star, Reactive Wheel Cleaner, or Insect & Dirt Remover) onto target area.
2. Select appropriately sized brush and agitate gently in circular motions to work up rich foam.
3. Rinse thoroughly with clean water before cleaner dries.
4. Rinse brush heads clean under running tap water and hang dry.
