Wheels and Tyres

Wheels live in the harshest chemical environment on your car: hot ferrous brake dust bonding to the finish, tyre browning from antiozonant waxes migrating to the rubber's surface, and road film over all of it. The wrong cleaner “works” by being aggressively acidic or caustic — and quietly etches alloy and powder coat with every wash. The right approach matches the chemistry to the contaminant: dedicated wheel cleaners and colour-changing iron removers for fallout, alkaline cleaners for browning and grime, and coatings or dressings to make the next wash easier.

Choose safely: your wheel cleaner is etching your wheels (and you can't tell yet) and a chemist's guide to choosing a wheel cleaner.
