Interior Car Detailing Course

Learn to detail a car interior properly — top to bottom, on any car, without guessing which product is safe on which surface.

This course covers the full interior detailing process the way it's actually done on a working car: which chemicals and tools do what, the order the cabin should be cleaned in, and how each material — leather, fabric, plastic, glass — needs to be treated differently.

What you'll work through:

• The chemicals, brushes, towels and tools that matter — the three or four products to start with, and what you can skip

• Preparation — setting the car up before a single product touches it

• The cabin top to bottom: roof lining, dashboard, leather, fabric seats and carpets, floors and trunk, glass and final checkup

• Leather in depth — telling the types apart and cleaning each one without damaging it

• Stubborn stains, streak-free glass, and the problems that only show up in direct sunlight

• A complete interior detail on a real car, start to finish, in one uninterrupted walkthrough

• Interior detailing as a paid service — timing, what customers expect

• The most common interior detailing myths, and what's actually true

Lessons are split into theory and practice. Each part of the interior gets its own lesson with its own chemicals, its own tools, and its own DO's and DON'Ts, so you're never left wondering whether what's in your hand is safe on the surface in front of you.

The longest lesson in the course is a full interior detail from start to finish. There I take a more direct approach and show the real workflow — where the time goes, where it's worth slowing down, and where you can save half an hour without losing anything. There are also deep-dive lessons on leather and on chemicals for anyone who wants the reasoning behind each step. Most of what's in this course is the kind of thing you'd otherwise pick up somewhere around your hundredth car — which is exactly why it's worth having up front.

Pet hair gets its own lesson, because it earns one. Not every carpet in a car is the same, and the type you are working on decides whether a rubber brush lifts the hair out or starts pulling the carpet apart. That lesson covers why the hair grips in the first place, how the three types of car carpet behave differently, which brush and vacuum combination belongs on each, and what to tell the customer before you take a job like that on if you are doing this as a service.

This is over ten years of my own experience — from running a detailing shop, and from distributing and testing professional car care products at the same time. Teaching has always been my favorite part of this trade, and the course is built the way I'd have wanted it explained to me: short lessons, no filler, and the small practical decisions that make the difference.

The core chapters also come with a downloadable written recap — the tools, the chemicals, the quantities and the DO's and DON'Ts for that part of the car — so you can print it and keep it where you actually work. Over 800 students have taken this course so far, and it holds a 4.7 rating. I keep adding lessons based on the questions students ask in the Q&A. Updated for 2026.
