How to Detail a Car
Detailing is not one job, it is five, and the reason people get disappointing results is almost always sequence rather than product. Wax over bonded contamination locks the contamination in. Polishing a car that has not been decontaminated drags grit across the paint. Cleaning the wheels last spatters brake dust over panels you just finished.

The order below is the one professionals use, and it is worth following even if you skip steps. Wheels, wash, decontaminate, correct, protect — outside in, dirtiest first, protection last. Do that and mediocre products give good results. Ignore it and the best products in the world will not.
What You Need
- A pH-neutral car wash soap: pH-neutral so it cleans without stripping whatever protection is already on the paint — our car wash soap guide, or check on Amazon
- A clay bar or decontamination kit: only if the paint fails the plastic bag test. If it feels like glass, skip this step entirely — our clay bar guide, or check on Amazon
- A dual action polisher: for the correction step, if there are swirls worth removing. Polishing removes clear coat, so it is not routine — our dual action polisher guide, or check on Amazon
- A drying towel: air-drying leaves mineral deposits that etch. Drying is not optional — our car drying towel guide, or check on Amazon
Detailing a Car, In Order
Wheels and tires first, always
Wheels carry brake dust and road grime that is far dirtier than anything on the paint, and the cleaners used on them are far harsher. Doing them first means any spatter lands on panels you have not washed yet.
Use a dedicated wheel cleaner and a separate set of brushes and buckets that never touch paint. Clean the tire sidewalls properly too — old dressing and brown oxidised rubber need a stiff brush, and the first time you do it the water will run brown.
Pre-rinse, then foam if you have a cannon
Rinse the whole car top-down to carry off loose grit before anything touches the paint. If you have a foam cannon, cover the car in foam and let it dwell for a few minutes — this lifts and suspends dirt so less of it is dragged by the mitt.
Foam is not a substitute for the contact wash. It reduces how much work the mitt has to do, which reduces swirl risk, and that is the whole benefit.
Two-bucket contact wash, top down
One bucket of soap solution, one of clean rinse water, grit guards in both. Wash top-down in straight lines rather than circles, rinsing the mitt in the rinse bucket between panels. The lower quarter of the car is where the coarse grit lives, so do it last and consider a separate mitt for it.
Keep the panels wet and stay out of direct sun. Soap drying on paint leaves deposits that etch.
Rinse and dry properly
Rinse thoroughly from the top down. Then dry immediately — do not let the car air-dry, because every mineral in your water stays behind as the droplets evaporate, and on a warm panel those deposits etch into the clear coat.
Lay a large drying towel flat on a panel and draw it toward you with almost no pressure. Do not scrub. A good towel absorbs by contact.
Decontaminate, but only if the paint needs it
Do the plastic bag test: put your hand in a sandwich bag and run your fingertips over the clean, dry paint. Glass-smooth means there is nothing to remove and claying would just be unnecessary mechanical contact with your clear coat. Gritty means bonded contamination and clay is the right tool.
If you clay, flood the panel with lubricant, work in straight lines in small sections, and knead the bar frequently to expose a clean face. Drop it on the ground and it goes in the bin.
Correct the paint, if there are defects worth removing
This is the optional step people treat as mandatory. Polishing removes a thin layer of clear coat, and a car only has so much to give — so polish when there are swirls or oxidation worth removing, not as a seasonal ritual.
If you do: dual action machine, least aggressive pad and compound that might work, test a small section first because paint hardness varies enormously between manufacturers. Two feet by two feet at a time, overlapping passes, light pressure, machine always moving.
Protect the paint
Everything so far has stripped or exposed the surface, and bare clear coat is vulnerable. Apply wax, sealant or a ceramic spray to cool panels out of direct sun, in thin even coats, and buff off to the manufacturer's timing.
This is the step that makes the next wash easier and the one people skip when they run out of afternoon. If you have to choose between correcting and protecting, protect.
Glass, trim, tires, then the interior
Finish the exterior with glass — inside and out, using a dedicated glass cleaner and two cloths, one to apply and one to buff. Dress the tires last so nothing splashes onto clean paint, and wipe the sidewalls after a few minutes so dressing does not sling.
Then the interior: vacuum first, then clean surfaces with a product safe across mixed plastics, and do the screen last with a screen-safe product sprayed onto the cloth rather than the display.
Safety: Work out of direct sunlight on cool panels throughout. Keep wheel cleaners off paint and trim, keep tire dressing off the tread and away from brake components, and never let any cleaner dry on a hot surface.
Common Mistakes
Doing the wheels last
Wheel cleaner and brake dust spatter onto paint you have just finished, and the harsh chemicals used on wheels are the last thing you want landing on fresh wax. Wheels first, with their own buckets and brushes that never touch paint.
Waxing over contamination
Protection applied over bonded contaminants seals them in and produces a finish that looks worse than bare clean paint. If the plastic bag test says the paint is gritty, decontaminate before you protect — or accept that the wax is wasted.
Polishing as routine maintenance
Every polish removes clear coat permanently, and there is a finite amount. Polish to correct defects, not on a schedule. Washing correctly and protecting regularly is what stops the swirls appearing in the first place.
Letting the car air-dry
Every dissolved mineral in your water stays on the paint as the droplets evaporate, and on a warm panel those deposits etch in. Removing established water spots requires polishing, which removes clear coat. Dry the car.
Wheels, wash, decontaminate, correct, protect. Follow that order and an ordinary set of products produces a genuinely good result. The sequence matters more than anything you can buy.
Frequently Asked Questions
What order should you detail a car in?
Wheels and tires first, then pre-rinse and foam, then a two-bucket contact wash top-down, rinse and dry, decontaminate if needed, correct if there are defects, then protect. Finish with glass, trim dressing and the interior. Dirtiest first, protection last.
How long does it take to detail a car?
A thorough first detail including decontamination and machine polishing is comfortably half a day, and can run to a full day on neglected paint. A maintenance detail — wash, dry, protect, interior — is closer to two hours once the car is in good condition.
Do you have to clay a car every time?
No. Clay only when the paint fails the plastic bag test, which for most cars is once or twice a year at most and for a garaged car may be never. Claying is mechanical contact with your clear coat, so doing it unnecessarily is a small cost with no benefit.
Should you polish or wax first?
Polish first, then wax. Polishing levels the clear coat to remove defects; wax adds a protective layer on top. Waxing before polishing means you immediately remove the wax you just applied. And if you polish, always protect afterwards — polished paint is left bare.
Can you detail a car in direct sunlight?
You should not. Products flash off before they can be worked or levelled, soap dries on panels and leaves deposits, and hot surfaces make almost every step harder and riskier. Work in shade or a garage, on panels cool to the touch — early morning or evening in summer.

How We Write Guides
Every product named in the “what you need” section is one we have researched and written about separately, and each links to that guide so you can see the reasoning rather than taking a recommendation on trust. We publish no prices, because they change faster than we can update pages. Where a job carries genuine risk we say so plainly rather than burying it, and where a job is beyond a home mechanic we say that too. Last reviewed August 10, 2026.
A note on safety: Keep wheel cleaning tools separate from paint tools. A brush used on brake dust will carry that grit onto your paintwork.
