Exterior car detailing across West London and Heathrow

Four corridors

What the detail lifts from each part of the west

The M4 corridor: Hounslow, Feltham, Southall, Slough

Soot and iron. Europe's busiest airport lands over the TW post town and Southall, and the film that settles is oily, holds water and works into lacquer over a season; the motorway underneath fires brake dust into the paint and the alloys. The decontamination dissolves both, the clay lifts what is left, the wax means next month's film rinses off. Slough's town centre is a demolition site from this year, with the Queensmere centre closed in January 2026 and coming down by December, and the cement dust on a car parked nearby is a clay job, never a cloth job.

The A40: Ealing, Hanwell, Greenford, Northolt

Honeydew and tar. The limes of the Queen of the Suburbs drip from June to September and the sugar bakes into rings on a Pitshanger roof; the Western Avenue's resurfacing throws tar onto the sills of every Greenford and Northolt car. The clay lifts the rings, the tar remover takes the sills back to black without rubbing, and the wax goes on before the salt.

The Metropolitan line: Harrow

Sap and school traffic. Metroland's avenues and the Hill's limes put a summer of sap on the newest cars in the west, and the detail valet's polish softens the etching a wash reveals. For a Harrow lease car, the detail the week before the hand back is the best money spent on the return.

The river: Staines, Twickenham, Sunbury

Salt and damp. A car between the Thames and the Colne spends the winter wet, with the M25 and the M3 adding spray, and salt on wet paint for months is what dulls it. The detail in April lifts the winter off; the wax means the next one beads away. Twickenham's riverside drives add the rugby crowds' grit and nothing the detail cannot shift.

How often

Twice a year everywhere, three times under the approach

Hounslow's gritters go out from mid November, Bath Road and Staines Road first, and Ealing, Harrow, Spelthorne and Slough salt their main roads with them, which gives the detail its two usual dates. April, when a winter of salt, iron and tar has bonded to the paint and needs lifting before the summer; September, when the summer's sap and site dust come off before the salt returns. Under the airport's approach there is a third, in midsummer, because the film does not stop for the weather. For a car worth keeping for years the September detail is the preparation for a ceramic coating; for a car going on sale or back to a lease company, the week before is the date that always pays.

The booking takes a minute: the postcode, which the page checks against the Network's coverage, then the Exterior Detail and a window. With the clocks gone back on 25 October the 10am window is the sensible one, because the washer needs two to three hours of daylight. A drive is best; a kerb space in a Southall terrace works at a quiet hour, and a bay under a Hounslow tower works if it is dry and the washer can get all the way round. The one thing the day has to be is dry, or the wax will not bond, and the washer will move a booking rather than wax wet paint. Water and power arrive in the van.

Details we do across the west

• Feltham car under the approach: the detail three times a year for the soot film, waxed between.
• Southall M4 commuter with brown wheels: the detail; the iron remover does what scrubbing cannot.
• Ealing car with honeydew rings after a summer under the limes: the detail, then a wax to stop next year's.
• Staines car after a wet winter: the detail in April, wax on for the summer.
• Slough car parked near the Queensmere demolition: the detail for the cement film, the only safe way to lift it.
• Harrow lease car going back: the detail the week before, then the end of lease clean.
