Detailing Interior Standard Operating Procedure

Interior Detailing Process

Set up the vehicle properly before starting.

Work in a consistent order (one corner around) for efficiency.

---

Preparation

  • Pull the car into your workspace. Crack or lower all windows to prevent lockouts and improve cabin light (especially with tinted windows).
  • Open all doors, trunk, and hood (this is called the “butterfly” setup).

---

Initial Cleaning

  • Use compressed air to blow out debris from under/between seats, vents, rear shelf, door pockets, and cubbies. Direct debris out the open doors.
  • Do a quick vacuum to remove loose debris. Perfection isn’t required yet.

---

Fabrics

  • Starting at the driver’s corner, spray pre-treatment on carpet and upholstery. Work your way around the entire vehicle spraying only.
  • Return to your starting point and agitate the pre-treated areas with a brush.

Fabric Cleaning Options

  • Extractor: Perform full fabric extraction.
  • No Extractor: Spray carpet cleaner, agitate with a brush, and wipe with microfiber.
  • Steamer: Scrub fabrics with steam.

---

Plastics, Leather & Vinyl

  • Start at one corner and work in quarters around the vehicle.
  • Spray interior cleaner and scrub with the appropriate brush.
  • Use compressed air and towels to dry and remove excess cleaner.

---

Headliner & Visors

  • Use ONR solution (256:1) on a wrung-out microfiber towel.
  • Wipe visors and headliner gently to clean without staining.

---

Conditioning & Glass

  • Apply interior dressing or leather conditioner to seats.
  • Roll windows up, then drop about ¼ inch for ventilation.
  • Clean all interior glass.

---

Final Touches

  • Perform a final vacuum. Move seats forward and back to reach crevices. Use compressed air if needed.
  • Turn HVAC to floor mode to speed carpet drying, or leave in butterfly mode under the sun.
  • If dressing the engine bay, spray water-based dressing on plastics and rubber during the initial blowout stage and let it dwell.
  • Extract or vacuum water from floor mats. Hang or sun-dry completely before reinstalling.
