Detail Factory is Canadian, based in Ontario, and makes brushes and hand tools rather than chemistry. The Ultra-Soft detailing brushes, the ProGrip wheel face brush and the Curveball wheel tool are the core of the range.
The filament is the argument. Detail Factory’s synthetic bristles are soft enough to use on a coated wheel face or a piano-black interior trim panel without marring it, and stiff enough to actually move dirt — a combination that most boar’s hair and most nylon brushes miss in opposite directions.
Being Canadian also means no import delay and no exchange-rate surprise, which for a consumable is worth something.
The range is narrow by design. This is a brush company, not a detailing brand, and it is better for it.
