Road & Track tested premium leather cleaners on a vintage Jaguar XJS to determine whether these products can restore aged hides without damage. The publication subjected well-worn interior leather to rigorous cleaning protocols, pushing products beyond typical household use to see if they deliver genuine results or merely marketing promises.
The XJS serves as the perfect test vehicle. Its decades-old leather presents real-world challenges. fading, buildup, and brittleness that challenge any cleaner's claims. Rather than abstract lab conditions, Road & Track evaluated how these formulations performed on actual aged materials under stress.
The testing cuts through the noise in the automotive detailing market, where products frequently overstate their capabilities. By selecting a specific, challenging platform with genuine age-related wear, the publication established measurable benchmarks for performance. The test answers a question many classic car owners face. can off-the-shelf cleaners restore value to their interiors without professional restoration costs.
This approach reflects how automotive journalism should operate. specific vehicles, specific products, specific results. Not generalities or manufacturer claims. The Jaguar XJS, with its notoriously aged leather, provides the ideal proving ground for separating legitimate restoration chemistry from marketing hyperbole.
