Before booking a deep cleaning, you have a practical question: how long will the car be at the shop? Will it be enough for one working day, or do you need a replacement vehicle? The answer depends on several factors, which we explain in detail.
Average deep cleaning times
Deep cleaning isn’t a quick job — a professional detailer takes time on every detail. Approximate times by vehicle type:
| Vehicle type | Interior only | Interior + exterior | Full detailing + protection |
|---|---|---|---|
| Small car (Polo, Fiesta, Yaris) | 2–3 hours | 3–5 hours | 6–8 hours |
| Mid-size sedan (Golf, Octavia, Focus) | 3–4 hours | 4–6 hours | 7–10 hours |
| SUV / estate (Tiguan, Passat, 5008) | 4–5 hours | 5–8 hours | 8–12 hours |
| Van / minivan (Transporter, Vito) | 5–7 hours | 6–9 hours | 10–14 hours |
| Pickup / large SUV (Hilux, Land Cruiser) | 5–7 hours | 7–10 hours | 12–16 hours |
Note: These times apply to an averagely dirty vehicle. A seriously neglected vehicle with years of accumulated dirt requires significantly more time.
Factors that extend cleaning time
Detailers say the longest cleaning job they’ve ever done took 3 full days. What causes such deviations?
Pets — especially dogs
Dog hair is without a doubt the hardest thing to clean out of an interior. It gets pushed deep into seat fabric and carpet fibers, and static holds it in place. One Labrador that rode in the back seat for a year can extend cleaning time by 2–4 hours just for hair removal.
Smoking in the vehicle
Nicotine and tar settle on every surface — the headliner, dashboard, vents, windows. The odor must be removed with ozone treatment (2–4 hours for ozone treatment alone) and intensive cleaning of all surfaces. Cleaning a vehicle that’s been smoked in for years takes 6–10 hours.
Food and drink
Food wedged into gaps between seats, dried spilled drinks in the carpet, old stains on the seats — each requires special treatment. Old milk or juice stains that have fermented into the fibers are especially difficult.
Children in the back seat
Parents of children under 5 know the scene: the carpet is full of crumbs, the seats have stains from play-dough, juice, and chocolate, and thousands of tiny toys hide in the gaps. Cleaning such an interior takes 1–2 hours longer than average.
Exterior condition
A vehicle that’s never been polished has years of insects, tar, iron particles, and water spots baked onto the paint. Exterior decontamination alone takes 1–2 hours, and polishing another 2–4 hours.
Leather
Leather seats require special cleaners, soft brushes, and gentle handling so as not to damage the surface. Cleaning and conditioning leather adds 30–60 minutes to the cleaning time.
What exactly does a deep cleaning include?
To understand why it takes so long, here’s what a detailer actually does:
Interior:
- Removing seats (for a thorough cleaning) or lifting seats to clean underneath
- Vacuuming the entire interior — seats, carpets, trunk, crevices
- Shampooing seats with an extraction vacuum (the machine injects solution and immediately extracts it)
- Shampooing the carpet
- Hand-cleaning the dashboard, center console, doors — every crevice individually
- Cleaning the headliner (especially demanding)
- Cleaning windows from the inside (often neglected, but essential for clear visibility)
- Cleaning air vents
- Protecting plastics with a UV protectant
- Protecting leather (balm or protective cream)
Exterior:
- Pre-wash with snow foam for gentler dirt removal
- Hand wash using the two-bucket method
- Cleaning wheels and tires
- Paint decontamination (iron remover, clay bar)
- Drying with microfiber towels
- Polishing (upon request)
- Applying wax, sealant, or ceramic coating
- Cleaning exterior glass
Mobile cleaning vs. shop cleaning — is there a difference in time?
Mobile detailers come to you with all their equipment — trailer, generator, water. Cleaning time is the same; the only difference is that you don’t lose time traveling. The one downside of mobile cleaning is weather dependency — cleaning the exterior after rain is more difficult.
How to prepare for faster, cheaper cleaning?
Before the detailer arrives (or before you drop off the car), do this:
- Remove all personal items — clothing, toys, bags, documents. Every item the detailer has to move costs time (= money).
- Empty the trunk — the detailer needs access to every part of it
- Find your service agreement — know exactly which services are included
- Tell the detailer about specifics — “there’s a dog riding in the back,” “my kids like to eat in the car” — this helps the detailer prepare properly
When is the car dry and ready to drive?
After deep shampooing, the interior stays damp for 1–4 hours, depending on temperature and ventilation. Professional detailers use industrial air dryers, which shorten the drying time. Seats and carpets are completely dry within 2–6 hours after cleaning, or up to 12 hours in cold temperatures.
There’s no lingering shampoo smell — once dry, the seats are fresh and odor-free.
Summary
For a typical moderately dirty vehicle, expect 3–5 hours for a deep interior and exterior cleaning. Set aside a full working day, and don’t plan to drive right after cleaning — let the interior dry properly.
