How long does it take to detail a car exterior?

Three to four hours for a maintenance detail, five to six if the paint needs decontaminating, and a full weekend if it needs correcting. The correction is what turns a long morning into two days.

Can you detail a car in one day?

A maintenance detail easily, and a decontamination detail comfortably. A full correction compressed into one day usually means correcting while tired, which is exactly when mistakes happen on vertical panels and edges.

What is the difference between a wash and a detail?

A wash removes loose dirt. A detail also removes bonded contamination, corrects defects if needed, applies protection, and covers the areas a wash skips — door shuts, jambs, trim, glass edges and wheels properly.

Do you need to decontaminate every time you detail?

No. Chemical and mechanical decontamination are twice-a-year jobs, triggered by the bag test rather than a schedule. Doing them more often than the paint needs costs clear coat and achieves nothing.

How to detail your car exterior

A full exterior detail is a weekend. Here is the whole thing with honest timings, and the shorter version for when a weekend is not available.

How this is funded: we earn an Amazon commission when you buy through our links, at no extra cost to you. We sell nothing and stock nothing, so a pick is never a product we are trying to move. Prices are pulled live from Amazon and were last checked October 5, 2026; where we cannot verify a price we say so rather than print an old one. Full disclosure.

Research-basedPicked from published specifications and the pattern across verified-purchase reports. We have not used these ourselves and do not pretend otherwise.How we pick

An exterior detail covers everything from the wheels to the glass. Done fully with correction it is a weekend; done as maintenance it is a long morning. The first question is which one your car actually needs.

Which version do you need

Matching the job to the car
If the paint...	Do	Time
Beads water and looks good in sun	Maintenance detail	3 to 4 hours
Feels rough through a plastic bag	Add decontamination	5 to 6 hours
Shows swirl marks in direct sunlight	Full detail with correction	A weekend
Is dull with no gloss at all	Full detail with correction	A weekend, possibly two days

What a full exterior detail uses

A foam cannon, an iron remover, a polisher and a durable wax. Prices are live from Amazon.

MJJC Foam Cannon S V3.0

Best for: The thickest foam of anything here

Our score8.9

$86.99

Price as of October 5, 2026. #ad

MJJC make the cannon that the rest of the market is measured against, and the S V3.0 produces foam that genuinely clings rather than sliding. Brass internals and a quarter-inch quick connector mean it fits almost any consumer pressure washer.

Who should skip it. Anyone without a pressure washer. A cannon needs the pressure and flow a machine produces, and on a garden hose it does nothing at all.

Foam thickness: 9.5
Build: 9.0
Adjustability: 9.0
Value: 7.5

What works

The thickest, longest-clinging foam in this group
Brass internals rather than plastic
Universal quarter-inch fitting

What does not

Useless without a pressure washer
Most expensive cannon here
MJJC does not publish a bottle capacity we could verify

Published specifications

Connector: 1/4 in quick connect
Bottle: Not published
Adjustable: Yes — foam ratio and spray pattern
Internals: Brass
Requires: Pressure washer

Gyeon Iron Paint Cleaner and Fallout Remover

Best for: The iron remover to buy if you buy one

Our score8.7

$34.99

$34.99At Amazon

Price as of October 5, 2026. #ad

A color-change iron remover that works fast and smells less offensive than most — which sounds trivial until you have sprayed a whole car with the alternative. The purple bleed is the reaction dissolving bonded brake dust so a clay bar does not have to tear it out.

Who should skip it. Routine washing. Iron removers are a twice-a-year job, and using one monthly is both wasteful and harder on trim than it needs to be.

Speed: 9.0
Dwell behavior: 8.5
Finish safety: 9.0
Value: 8.0

What works

Fast, clear color change so you can see it working
Markedly less offensive smell than most
Safe on coated paint and painted wheels

What does not

A twice-yearly product, not a routine one
GYEON does not publish a bottle volume we could verify
Must be rinsed before it dries, which limits panel size in sun

Published specifications

Volume: Not published
Type: Color-change iron remover
Dwell time: Do not let it dry
Coating safe: Yes
Wheel safe: Yes on painted and coated finishes

Griot's Garage G9 Random Orbital Polisher

Best for: The default answer for a first serious machine

Our score8.7

$179.99

$179.99At Amazon

Price as of October 5, 2026. #ad

A 9mm throw and a 1000W motor put the G9 exactly where most home detailers should be: fast enough to finish a car in an afternoon, short enough in the throw to stay predictable near badges and body lines. It is the machine we would buy if we were buying one machine.

Who should skip it. If you already own a competent 8mm machine, this is not the upgrade you think it is — the extra millimeter of throw will not fix inconsistent results. Put the money into better pads and a second liquid instead. It is also heavier than the G8, and you notice that on vertical panels after an hour.

Correction speed: 8.5
Control: 9.0
Ergonomics: 7.5
Build: 9.0
Value: 8.5

What works

9mm throw is the best general-purpose compromise on the market
1000W does not bog down under pressure on a cutting pad
Griot's lifetime warranty is the strongest in the category
Takes the same 5 in plate and 5.5 in pads as everything else

What does not

Heavier than the G8, which shows on doors and quarters
Noticeably louder at speeds five and six
No pad or liquid in the box at this price

Published specifications

Throw: 9mm
Motor: 1000W
Speed settings: Variable, 6 positions
Backing plate: 5 in
Warranty: Lifetime, per Griot's Garage

Collinite 845 Insulator Wax

Best for: Outlasting every other wax here, by a lot

Our score8.7

$20.95

$20.95At Amazon

Price as of October 5, 2026. #ad

845 is a carnauba and polymer hybrid originally formulated for electrical insulators, and it is the most durable thing in this roundup that still calls itself a wax. Six months outdoors is realistic where a pure carnauba manages six weeks.

Who should skip it. Anyone chasing the deepest carnauba glow. 845 looks good rather than spectacular, and it is thin and runny out of the bottle, which takes getting used to.

Durability: 9.5
Gloss: 7.5
Ease of use: 7.0
Value: 9.5

What works

Comfortably the longest-lasting wax here
Genuinely cheap per application
Excellent in winter and on cars that live outdoors

What does not

Thin and runny — easy to over-apply on the first try
Less depth than a dedicated show carnauba
Collinite does not publish a bottle volume we could verify

Published specifications

Type: Carnauba and polymer hybrid
Claimed durability: Up to 6 months, per Collinite
Volume: Not published
Form: Liquid
Coating safe: No — do not layer over a ceramic coating

The maintenance detail, 3 to 4 hours

The full detail, a weekend

Saturday morning — wash and decontaminate

The maintenance wash above, through the drying step.
[Iron remover](/washing/best-iron-removers) panel by panel, dwell, rinse. 45 minutes.
Bag test. If the paint is still rough, clay it. 60 to 90 minutes.
Dry completely and move the car into shade or a garage.

Saturday afternoon — correct

Tape every edge, badge and body line. 30 minutes, and non-negotiable.
Test a 2 ft section to find your pad and liquid combination. 20 minutes.
Correct the horizontal panels — hood, roof, trunk — while you are freshest. 2 to 3 hours.
Stop when you are tired. Fatigue on a vertical panel is where mistakes happen.

Sunday morning — finish correcting

Vertical panels and bumpers, 2 to 3 hours.
Inspect everything under a light before you call it done.
Remove the tape.

Sunday afternoon — protect and finish

Panel wipe if a coating is going on. 30 minutes.
Apply [protection](/protection/best-paint-sealants), 60 to 90 minutes.
Dress the tires and trim, 20 minutes.
Glass last, 20 minutes.
Leave it dry overnight if you applied a coating.

What people forget

Door shuts and jambs. They take ten minutes and they are what separates a detailed car from a washed one.
The fuel filler area, which collects more grime than anywhere else on the car.
Exhaust tips, which respond dramatically to a metal polish.
Under the hood, which does not need to be detailed and does need a wipe of the shuts and the edges.
The glass top edge, with the window lowered an inch so the strip in the seal gets cleaned.
