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.

"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 DivisionWhat Makes It Work
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
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.
