In this video I’m tackling a straight-up disaster detail—an interior deep clean on a super dirty Ford Expedition. I show you how I approach a filthy cabin the professional way: start with a solid vacuum to get all the loose mess out, then I go in with steam and agitation to break down the grime that’s stuck in the seats, carpets, and all the tight areas. This is the kind of job where patience matters, because you can’t just “wipe and hope” when the interior is this bad. I’m also using my go-to tools to make the process faster and cleaner—my RIDGID portable vac with the detailing hose kit to reach cracks and crevices, plus my McCulloch steamer to help lift gunk without soaking everything. For leather, I keep it simple: clean it properly, then condition it so it doesn’t dry out after you remove all that dirt. If you’re trying to learn how to deep clean a nasty interior step-by-step, this one is for you—good vibes, real results, and no shortcuts.
