This is the standard scope. It does not change by neighborhood, by how nice the car is, or by who is watching.
The order matters more than most people expect. We work top-down and dry-to-wet, because doing it the other way round means the dust you knock off the headliner lands on carpets you already cleaned.
Vacuum, properly
Seats, seat backs, the seams between cushions, under the seats, the seat rails, the carpets, the mats separately, the boot or cargo area, and the spare-wheel well if it opens. The rails and the gap between seat and center console are where the actual volume of debris lives, and they are the first thing skipped on a fifteen-minute wash-and-vac.
Hard surfaces
Dash, instrument binnacle, center console, gear surround, door cards, door jambs, sills, grab handles, steering wheel, stalks, and the pillars. Vents get compressed air and a detailing brush rather than a wipe, because a wipe just packs the dust further in.
Screens and gloss-black trim get a dedicated microfibre and a light touch. Gloss piano-black is the single easiest surface in a modern car to scratch, and it scratches from dry wiping.
Glass
All of it, inside, including the top edge of the windscreen where the film builds up worst and the rear glass on hatchbacks. Streak-free glass is one of the two things people notice within ten seconds of getting back in, the other being smell.
Leather and upholstery
Leather is cleaned with a pH-appropriate cleaner and then conditioned. Cloth gets an interior cleaner worked in and lifted; this is a surface clean rather than a full extraction, which is a separate service.
If your car has perforated leather, tell us. Perforated seats hold liquid in the holes and need a different, drier method than solid leather.
Finish
Mats back in, everything reset the way you left it, and a deodorize. Then a walkthrough with you before we pack up, or a set of photos texted over if you handed us a key and went to work.
