- Every surface needs its own product: plastics, leather, fabric and glass react differently.
- Do the glass last, so any overspray from cleaners and dressings is wiped away with it.
It's easy to spend a Sunday on the paintwork and forget the part of the car you actually sit in. Dust on the dashboard, crumbs in the seat rails, a greasy film on the inside of the windscreen: none of it is dramatic, but together it makes the car feel older than it is. The good news is that a proper interior clean doesn't need special skills. It needs the right order and the right product for each surface.
Before you start
Park in the shade with the doors open. Cleaners and dressings dry too fast on hot plastics and glass, which is how streaks and patchy finishes happen. Take everything out: mats, child seats, the clutter in the door pockets and the boot. You can't clean around things properly.
Give the floor mats a shake and set them aside. Rubber mats can be scrubbed and rinsed now so they have time to dry; carpet mats get vacuumed with the rest of the car.
Vacuum first, thoroughly
There's no point wiping a dashboard while grit is still being kicked up from the footwells. Vacuum from the top down: headlining edges, seat backs, seat bases, then the carpet. Slide each front seat fully forward and then fully back so you can reach the rails, because that's where most of the debris hides. A soft brush attachment lifts dust from air vents and switchgear without scratching them.
Plastics and trim
Dashboards, door cards and centre consoles collect dust, fingerprints and sticky residue from hands and drinks. The key is to clean first and dress second. Dressing over dirt simply seals it in and leaves a blotchy finish.
- Clean. Apply a small amount of Plastic Cleaner Cola onto a microfibre cloth or a soft brush rather than spraying it straight onto the dash. Work it over the surface, using the brush on textured areas and around buttons.
- Wipe dry. Collect the lifted dirt and any excess product with a clean, dry microfibre. The cleaner doesn't need rinsing.
- Let it evaporate. Leave the surface for a few minutes before dressing, so the cleaner has fully evaporated.
- Dress. Apply a little Interior Dressing with an applicator or microfibre and buff off any excess. It restores colour depth, leaves a UV filter to help prevent fading and forms an antistatic layer, so dust settles less quickly.
Keep dressing off the steering wheel, pedals and gear lever. Anything that leaves a slick finish on a surface you grip or press is a safety risk. Keep interior dressing off upholstery and windows too.
Leather seats
Leather dries out and cracks when it's neglected, and the side bolsters of the driver's seat usually go first because they take the most wear. Clean it gently, then condition it.
Start by checking what you have. Smooth, coated leather (what most cars use) is fine for standard leather care. Nubuck, suede, velour and aniline leather are not, so check your handbook if you're unsure. Test any product on a hidden area first.
- Clean lightly. Remove surface dirt with a leather cleaner and a soft brush, then wipe with a microfibre.
- Condition. Apply Leather Conditioner Matt with a soft microfibre or applicator in circular movements, spread it evenly and leave it to dry. It keeps the leather supple, leaves a matt, non-greasy finish and helps protect against UV.
- Maintain. Between deep cleans, a quick wipe with Leather Quick Detailer keeps lightly soiled leather fresh. It is designed to be safe for use every couple of weeks and also works on eco leather.
Fabric seats and carpets
Cloth seats hide dirt well, which is exactly why they can look fine and still smell stale. Vacuum them slowly with a brush attachment to lift embedded grit, then work a fabric cleaner into the material with a soft brush and lift the dirt out with a clean, slightly damp microfibre. Don't soak the seat: too much liquid takes a long time to dry and can leave a tide mark. Tackle fresh stains straight away, because the longer they sit, the harder they are to remove.
Glass: always last
The inside of the windscreen builds up a greasy film from the dashboard and from breathing, and it's what causes glare on low winter sun. Do it last, so any overspray from the cleaners and dressings comes off at the same time.
Spray Glass Cleaner onto a microfibre rather than onto the glass inside the car, wipe in straight lines, then buff dry with a second, dry cloth. It has a streak-free formula and cuts through heavy grease on interior glass.
Pro tip: wear gloves when you do the glass. Grease from your fingers transfers to the microfibre and straight back onto the windscreen, which is where most "mystery streaks" come from.
Which product for which surface?
| Surface | Clean with | Finish with |
|---|---|---|
| Dashboard and door cards | Plastic Cleaner | Interior Dressing |
| Smooth leather seats | Leather cleaner | Leather Conditioner Matt |
| Leather, between cleans | Leather Quick Detailer | Nothing else needed |
| Cloth seats and carpets | Fabric cleaner and a soft brush | Leave to dry fully |
| Windows and mirrors | Glass Cleaner | Dry microfibre buff |
How often should you do it?
A quick vacuum and wipe-down every couple of weeks keeps most interiors in good shape. A full clean like this one, including conditioning the leather, is worth doing every one to three months depending on how the car is used. Family cars, dog owners and anyone who eats on the move will need it more often.
Clean first, dress second, glass last. Get the order right and the job is half done.
Frequently asked questions
What order should I clean my car interior in?
Declutter and remove the mats, vacuum everything, then clean from the top down: plastics and trim, seats, and the glass last. Dress the plastics and refit the mats at the end.
Can I use one product on every surface?
It's best not to. Plastics, leather, fabric and glass each respond best to a product designed for them, and using the wrong one can leave residue, streaks or a slippery finish.
How often should I condition leather seats?
Every one to three months keeps smooth leather supple, depending on use and how much sun the car gets. Use a quick detailer in between for light cleaning.
Why does my windscreen smear after cleaning?
Usually grease from your hands or a dirty cloth. Use a clean microfibre, wear gloves, and buff dry with a second cloth.
Is interior dressing safe on the steering wheel?
No. Keep dressing off the steering wheel, pedals and gear lever, as well as upholstery and glass.
