Researched as the category benchmark all-in-one: a single spray that cleans and leaves UV protection on nearly every interior surface, backed by the largest review base in the segment at almost 46,000 ratings. It dries to a matte, streak-free, non-greasy finish rather than a wet shine.

Researched as the dedicated leather-care pick: a combined cleaner and conditioner with UVX-15 sunscreen that cleans finished leather and restores suppleness in one step, aimed at seats and steering wheels the all-rounders only lightly wipe. Meant for finished leather, not raw or suede.

Researched as the deep-cleaning workhorse for stains: a concentrated all-purpose cleaner that lifts embedded dirt and grease from carpet, upholstery, leather and plastic, shipped with a microfiber towel. It is a cleaner, not a protectant, so it leaves no UV shield behind.

Researched as the budget anchor: the ubiquitous glossy protectant that dresses vinyl, rubber and plastic and blocks UV for under six dollars. The finish is deliberately shiny — great for a 'new car' look, less so for owners who prefer a factory-matte dash.
