Complete vehicle care is not limited to paint and wheels. This one-day course focused on the structure of professional interior cleaning.

A concise theory section introduced glass, dashboard, leather, upholstery, plastic and carpet care. Each material requires its own chemistry, tools and drying considerations.

Vacuuming provides the foundation. The first pass removes loose dirt; detailed work then releases dust from seat rails, console seams and the space between seats and doors. A second pass collects what has been brought to the surface.

Plastics and dashboards require more judgement than they appear to. Product choice, dilution and wiping technique determine whether the result is even and natural or streaked and greasy.

Textile and leather seats present different risks. The wrong cleaner can cause colour loss, hardening or tide marks. Participants learned to test products, control moisture and clean seams and contact areas without overworking the material.

Interior protection was taught as an optional, material-specific stage rather than one universal sealant. Textile, leather and plastics each need a compatible system, and untreated gaps must be avoided where they would create a visible difference later.

A garage employee who completed the course reported that customer feedback improved after the business expanded from routine vacuuming into structured interior care.

The course provided a practical foundation. Continued experience remains essential, particularly for delicate leather, headliners, electronics and heavily contaminated interiors.
