Which Detailing Service Does Your Car Actually Need?

Short answer

Almost every car falls out of four tests you can run yourself in two minutes: the palm test on the carpet, the back-of-hand test on the paint, the torch test for swirls, and the door test for smell.

Whatever those four tell you, the base service is the same three choices — interior, exterior, or both. The tests decide which add-ons go on top, and that is where the money actually differs.

Written so you can arrive at an answer without talking to anybody. If the answer is the cheapest option, that is a real result, not a preamble to an upsell.

Diagnose

The four tests, in order

Do these on a car that has not just been washed. You want it in its normal state.

  1. 01

    The door test — smell

    Open the door on a car that has been shut for a few hours and notice the first impression before your nose adapts. Sour or musty means a source in the carpet or seats. Nothing means your interior is fine and you can stop worrying about it.

  2. 02

    The palm test — carpet

    Press your hand flat on the carpet and drag it a foot. Grey palm means surface dirt, which a vacuum gets. Clean palm but flat, dull carpet means the soil is down in the fibre and only extraction reaches it.

  3. 03

    The back-of-hand test — paint

    Wash a panel, dry it, then run the back of your hand over it. Smooth means the paint is clean. Gritty means bonded contamination, which no amount of washing removes — that is decontamination, not a wash.

  4. 04

    The torch test — clear coat

    After dark, hold a phone torch close to the bonnet and move it around. A halo of fine circular scratching is swirl marks. If the paint looks deep and clean, you do not need correction and should not pay for it.

  5. 05

    The fingernail test — on anything you can see

    Drag a nail across a scratch or a water spot. If it does not catch, it is in the clear coat and correction can level it. If it catches, it is through the clear coat and correction will improve it rather than remove it.

  6. 06

    Now add up what you found

    Nothing from any test: a maintenance wash. Interior findings only: interior detail plus the matching add-on. Paint findings only: exterior plus decontamination. Both: Full Package. Torch findings: that is the correction conversation, and it is quoted.

The map

What each finding actually maps to

Sedan pricing. Find your row, add the add-on to the base, and you have your number before you contact anybody.

What you found What it needs Price on a sedan
Car is just dusty Exterior Wash & Protection $100
Interior is cluttered and dusty Interior Detail $229
Both, and it has been months Full Package $279
Carpet flat and grey, palm stays clean Full Package + carpet extraction $279 + $25 per area
Visible seat stains Interior Detail + seat extraction $229 + $25 per seat
Smell that comes back Interior Detail + odour treatment $229 + $50
Pet hair woven into the weave Interior Detail + pet hair removal $229 + $75
Paint gritty after a wash Exterior + iron decontamination + clay bar $100 + $75 + $50
Halo of swirls under a torch Paint correction, always with protection Quoted after we see it
Trim gone chalky grey Exterior + black trim restoration $100 + $75
Headlights yellowed Any service + headlight restoration $50 per headlight

Extraction is capped at $125 on a sedan or midsize and $175 on a large vehicle, so several areas at once never runs away. Midsize SUV and large vehicle bases are higher — the pricing guide has the full list.

By situation

If you would rather answer by situation than by test

It is just dirty

The most common case by a wide margin, and the cheapest. A Full Package or an exterior wash, no add-ons.

Most cars that arrive expecting correction actually need this.

Something happened in it

A spill, a dog, a smell. The base interior detail plus the one add-on that targets it. See the stain guide.

You are selling it

Spend where a buyer looks, not where the paint is worst. The selling guide has the budget.

You want it to stay good

That is protection rather than cleaning. Sealant or coating — see choosing a package.

Honest

Signs you do NOT need what you might be about to buy

We would rather you booked the smaller job and came back than felt sold to once.

  • Paint looks clean under a torch: you do not need paint correction. It removes clear coat you cannot get back, and there is nothing to remove.
  • Your palm comes up grey: that is surface dirt. A vacuum gets it. You do not need extraction.
  • No smell when you open the door: you do not need odour treatment. There is nothing to treat.
  • Paint is smooth after a wash: you do not need decontamination this year.
  • You are handing the car back in six months: you almost certainly do not need a ceramic coating.
  • Only one half of the car is a problem: book that half. The Full Package is good value when both need work and wasted money when one does not.

Or just send photos and skip all of this

Four photos — driver's footwell, back seat, a paint panel in daylight, and the front of the car — and we will tell you which row of that table you are on.

It costs nothing, it is not a sales call, and the answer is often the cheaper service.

Questions

Questions we get asked

How do I know if I need paint correction or just a wash?
The torch test. After dark, hold a phone torch close to the bonnet. A halo of fine circular scratching means swirl marks, which only machine polishing removes. Paint that looks deep and clean under that light does not need correcting, and we will tell you so.
How do I know if I need extraction?
Press your hand flat on the carpet and drag it a foot. If your palm comes up grey the dirt is on the surface and a vacuum will get it. If your palm stays clean but the carpet still looks flat and dull, the soil is in the fibre and only hot-water extraction reaches it.
Can you just tell me what my car needs?
Yes, and that is usually faster than working through it yourself. Send a few photos with a quote request — footwell, back seat, a paint panel in daylight — and we will tell you which service and which add-ons, including when the answer is none of them.
What if I book the wrong service?
Tell us what you are trying to fix when you book and we will flag it before the appointment rather than turning up with the wrong plan. If we arrive and the car needs something different, we talk to you before doing anything.
Is the Full Package always better value?
Only when both halves need work. On a sedan it is $279 against $229 for the interior alone, so it is excellent value if the paint needs attention and wasted money if it does not.

Two minutes with a torch and your hand.

That is genuinely most of the diagnosis. Send photos if you would rather we did it.
