Koch Chemie Magic Wheel Cleaner (MWC) is a professional acid-free wheel cleaner with a built-in reactive iron remover that works two ways at once. The viscous formula clings to wheel surfaces and wheel wells without running or drying out, giving the active ingredients extended dwell time to penetrate and loosen contamination. As the iron remover reacts with embedded brake dust and metallic particles, the formula turns red, providing a visible indicator of the contamination level being broken down.

Acid-free chemistry makes it safe on all wheel finishes including painted, chrome, alloy, and clear-coated wheels without the risk of surface etching or damage associated with acid-based cleaners. Gentle dispersing agents lift stubborn dirt and grime cleanly for a thorough wash-off. One of the most versatile and complete wheel cleaning products in the Koch Chemie lineup.

If you are looking for an acid-free wheel cleaner with color-changing iron remover for professional detailing, a Koch Chemie wheel cleaner that clings to vertical surfaces for extended dwell time, or a safe and effective rim cleaner for all wheel types that removes both brake dust and iron fallout in a single product, MWC Magic Wheel Cleaner delivers complete wheel decontamination without acid risk. Available in 500ml and 5L.

Frequently Asked Questions

Koch Chemie MWC vs AWH — which should I use?

MWC is pH-neutral and iron-reactive — safe on all wheel finishes including anodized, forged, and polished. Use MWC for maintenance cleaning and any sensitive wheel. AWH is strongly alkaline — use it on heavily soiled painted/coated wheels when you need maximum cleaning power. Many shops carry both.

Is Koch Chemie MWC safe on all wheels?

Yes. MWC is pH-neutral and formulated to be safe on every wheel finish — painted, clear-coated, forged, polished, anodized, and ceramic-coated. This is one of its biggest advantages over alkaline wheel cleaners.

Does Koch Chemie MWC work on paint for iron decon?

Yes. MWC can be sprayed on cool paint to remove iron contamination as a full-body decon step. Spray, dwell 3-5 minutes until the product turns purple/red (visible iron reaction), agitate lightly, rinse thoroughly.

How long should I let Koch Chemie MWC dwell?

3-5 minutes on a cool surface. Don't let it dry — mist with water if you need to extend dwell. The color change (yellow to purple/red) shows the iron reaction is working.

What's the best MWC dilution for maintenance cleaning?

1:5 dilution is the right balance for regular wheel cleaning — enough strength to cut brake dust, diluted enough to be economical. Use straight on heavy contamination or as a paint decon step.
