Exterior detailing is a full reset of everything you can see and touch on the outside of your car. It goes well past a rinse and a soap pass. The goal is clean paint, protected paint, and surfaces that stay cleaner longer. Here is what a proper exterior service actually covers.

The wash

A real detail starts with a careful wash, not a quick one. That usually means a pre-rinse to lift loose grit, a foam or pre-soak to soften road film, then a two-bucket hand wash with clean media so you are not dragging dirt back across the paint. Done right, this stage removes the swirl-causing grime before anyone touches the surface with a mitt. It is the single biggest difference from an automated tunnel, where stiff brushes and recycled water tend to add fine scratches over time.

Decontamination

Washing removes what is loose. Decontamination removes what is bonded. After months on Montreal roads, paint picks up brake dust, industrial fallout, tar, and tree sap that soap alone will not budge. A detailer uses an iron remover and a clay bar (or clay mitt) to pull these out, leaving the surface glass-smooth. This step is what makes protection last. Our clay bar guide explains the feel test that tells you when paint needs it.

Wheels, tires, and glass

Wheels get the dirtiest and are cleaned first, with dedicated tools so wheel grime never touches your paint. Tires are scrubbed and usually dressed for a clean finish. Glass is cleaned inside and out, since streaky windows undo an otherwise sharp result.

Protection

The last stage seals your work in. A wax or a synthetic sealant lays down a sacrificial layer that repels water, blocks UV, and makes the next wash easier. Sealants generally outlast natural wax. For a harder, longer-lasting option, see ceramic coating. Protection does not fix existing scratches. That is paint correction, a separate service.

Exterior detail vs a basic wash

A basic wash cleans the surface for a few days. An exterior detail decontaminates, protects, and buys you weeks of easier upkeep, which matters through a salty Quebec winter. If you also want the cabin handled, compare an interior versus full detail. LuxWash is an early-access platform connecting Montréal drivers with vetted, independent detailers.
