Gtechniq W6 Iron and General Fallout Remover

Spray onto cool paint or wheels and the formula turns purple as it pulls iron contamination from the surface. The high-cling gel dwells longer on vertical wheel faces than thin-spray competitors. Dwell 3-5 minutes, rinse in one pass. Independent Detailing World and AutoGeek reports confirm thorough single-application removal even on rail-dust-contaminated paint. The active chemistry is acidic (SDS confirms pH 3.0), not pH-neutral despite the coating-safe marketing claims. Follow Gtechniq's dwell guidance on coated surfaces to avoid etching risk.

Ideal for enthusiasts maintaining ceramic-coated or PPF-covered paint where iron decontamination before a maintenance coat matters and contamination is severe. Skip it if you need a confirmed pH-neutral formula for extended dwell times on sensitive surfaces; the acidic pH is a real constraint.

The DANGER signal word is driven by H318 (serious eye damage Cat 1) in the SDS; wear safety goggles when handling, particularly when spraying wheel arches upward. H317 (skin sensitizer) means gloves are recommended at any contact level once sensitized. No inhalation H-codes at the mixture level; the strong sulfur odor during dwell is a real-world indicator of volatile exposure, so use outdoors. Three surfactant ingredients carry aquatic toxicity flags; avoid storm drain disposal. SDS §12 confirms biodegradable formula.
