Bendable Handle. Soft Nylon Bristles. Surface-Safe Tip. Built to reach where other brushes can't. The Koch Chemie Large Barrel Brush is a purpose-built wheel cleaning tool designed to reach deep into wheel barrels and navigate freely around spoke geometry. At 18" in length with a 5" diameter brush head, it covers ground fast — providing the access needed to clean what's hiding behind the face. The black & white nylon bristles are relatively soft by design — and when paired with the acid, alkaline, or iron-remover wheel cleaner of your choosing, the chemistry does the work. The brush agitates and lifts, not abrades. Generally wheel finish safe, but user should use caution no matter what. If you've used a similar 'EZ Brush' before, you know the concept. This is Koch Chemie's take on it — branded, well-built, and ready to earn its place in your wash setup. Length 18" Deep barrel reach Brush Diameter 5" Full barrel coverage Bristles Nylon Black & white · soft · chemical-safe "The bristles aren't here to do the heavy lifting — that's what the chemistry is for. Soft nylon paired with a quality wheel cleaner is the combination. The brush agitates, the product cleans." — Detail Division What Makes It Work Bendable Black Handle Flex it around spoke geometry, into the barrel, across tight caliper clearances — the handle goes where a rigid brush won't. 18" Length · 5" Diameter Long enough to reach the deepest barrels on staggered fitments. Wide enough to clean efficiently in a single pass rather than working in circles. Soft Black & White Nylon Bristles Not firm — not stiff. Soft nylon that works with your wheel cleaner, not against your rim finish. Chemical-safe for use with acid, alkaline, and iron-remover formulas alike. Protective Plastic Tip The brush tip is capped in plastic — so when it makes contact with the back of the barrel or brake hardware, it's the cap making contact, not the bristle core. No scratching, no marking. Branded Koch Chemie Plastic Handle Solid, well-finished handle with the Koch Chemie branding... made to the standard their chemistry demands. Works With Any Wheel Cleaner No restrictions on chemistry — run it with your acid-based cleaner, an alkaline formula, or an iron remover. The nylon bristles hold up across the board. The Right Tool For The Job A barrel brush is only as good as the wheel cleaner it's paired with. The brush agitates — the product dissolves. Pick a wheel cleaner matched to what you're dealing with: iron remover for brake dust and fallout, alkaline for general road grime, acid for heavy mineral and calcium buildup on neglected wheels. This brush handles the mechanical side of the equation. Load it with your chosen chemistry, work between spokes and across the inner barrel, let the combination do what neither can do alone. Simple tool. Specific purpose. If clean barrels and the back sides of spokes matter to your wash routine, this brush earns its place next to the bucket every time. At a Glance Koch Chemie · Since 1968 18" length · 5" diameter Soft nylon bristles · chemical-safe Bendable handle · spoke-friendly Protective plastic tip Acid · alkaline · iron remover safe Soft bristles work best with chemistry, not pressure. Apply your wheel cleaner of choice, allow appropriate dwell time, then agitate with the brush. Let the product do the dissolving — the brush handles the mechanical lift. Rinse thoroughly after use and store the brush clean.
