Koch-Chemie × THE FINISHER THE FINISHER "WheelKing" Wheel Cleaner 500ml

THE FINISHER × Koch-Chemie „WheelKing“ — Wheel Cleaner with Safe Reactive Power

What is WheelKing for? — The acid-free, reactive wheel cleaner reliably removes baked-on brake dust and rust film, adheres evenly as a gel, visibly changes color during reaction, and rinses off streak-free – for painted, powder-coated steel and and alloy wheels.

THE FINISHER WheelKing Wheel Cleaner is your go-to tool for dark brake dust and metallic deposits. The reactive gel formula wets complex designs deep into the wheel bed, chemically dissolves particles, and makes the reaction visible with its typical color change. This reduces the need for brushing, allows for controlled work, and achieves a consistent, clean finish on painted and powder-coated wheels – including painted brake calipers. In THE FINISHER system, WheelKing follows the pre-wash (TropicSnow) and precedes the contact wash (MagicShampoo); BodyGuard provides final protection if needed. In short: less scrubbing, more results – safe, swift, reproducible.

• Strong against brake dust: Reactive active ingredients tackle iron-containing deposits and dissolve rust film; the gel texture adheres for a long time to complex geometries.
• Gentle & controlled: Acid-free, pH-balanced, visible color-change indicator; suitable for painted/powder-coated steel and alloy wheels as well as painted calipers.
• Smooth Workflow: Perfectly integrated between TropicSnow (Pre-Wash) and MagicShampoo (Hand Wash); rinses cleanly and prepares the surface for protection.

Reactive Wheel Cleaner – Technology & Material Protection

Reactive wheel cleaners like THE FINISHER WheelKing Wheel Cleaner work by binding iron particles from brake dust and rust film. The gel structure ensures calm wetting, allowing active ingredients time to dissolve particles; the color change shows you where the reaction is taking place. Because the formulation is acid-free and pH-balanced, the work remains gentle on materials: clear coats, powder coatings, and painted brake calipers retain their shine and feel. For sensitive special surfaces – polished, unpainted, anodized – the rule is: test spot in a hidden area, short dwell time, immediate rinsing. Hot wheels, direct sunlight, and drying chemistry are taboo – this ensures a safe process.

Application on the Vehicle – Dwell Time, Tools & Procedure

Application is achieved with a few clean steps. Cool down and pre-wet wheels, then spray THE FINISHER WheelKing Wheel Cleaner generously from bottom to top. Allow to work for 2–4 minutes, do not let it dry. Use a soft wheel brush to agitate spokes, barrel, and edges; detail brushes are suitable for lug nut holes and valve areas. Then rinse thoroughly until no more foam streaks run. Now follows the exterior wash with MagicShampoo; the wash mitt glides smoothly over the already decontaminated wheel. If you want to increase protection and future ease of cleaning, finish with BodyGuard after drying – this visibly facilitates the next wash.

Results & Routine – Winter Dirt, Performance Wheels & Care Plan

Routine beats impulsiveness: Use THE FINISHER WheelKing Wheel Cleaner with every thorough wash or at least every two to three washes, depending on the amount of brake dust. For heavily used performance wheels or after winter drives, a second, short round with targeted brushing helps. Clean painted brake calipers at the same time, but avoid any application on hot components immediately after driving. After rinsing and hand washing, dry with a separate cloth to prevent water spots. A light, hydrophobic topping step (BodyGuard) significantly reduces adhesion – brake dust can then be rinsed off faster next time.

Frequently Asked Questions about THE FINISHER × Koch-Chemie „WheelKing“ — Wheel Cleaner

Is WheelKing suitable for all types of wheels?

Yes, for painted and powder-coated steel and alloy wheels, as well as painted brake calipers. For polished/unpainted metals and anodized surfaces, test beforehand, work briefly, and rinse thoroughly immediately.

How long should the cleaner be left to act?

2–4 minutes in the shade. Do not let it dry; work shorter in warm weather and re-mist if necessary. The color change indicates the ongoing reaction.

Does the product attack valves or TPMS?

Not with proper use. Do not use on hot components and always rinse completely after brushing – including the valve, nipple, and sensor housing areas.

Why do I also need a shampoo?

WheelKing chemically dissolves iron-containing dirt. The subsequent hand wash with MagicShampoo removes road grime and builds up lubricity and a protective film – keeping the surface clean longer.

Can I use WheelKing without brushing?

Yes, the chemistry works on its own. However, gentle mechanical assistance with a wheel brush or detail brush significantly improves results in corners, edges, and lug bolt channels.
