Home / Locations / Hertfordshire / Interior cleaning
A Hertfordshire car's cabin is a record of where it has been: the Chilterns on the mats in Hitchin, the Lea on the carpets in Hertford, a university term in Hatfield, a labrador in Harpenden. The outside gets washed because the neighbours see it. The inside gets the deep clean it needs about once a decade, usually the week before the car is sold. Yikes does it on the drive or at the kerb, in every town around Stevenage, through vetted local washers from the Yikes Network who bring the vacuum, the steam, the shampoo and the power. Stevenage has its own page; this one is the rest of the county.

What is included
Town by town
Chalk. The lanes out to Pirton, Offley and St Ippolyts leave white dust in the footwells and the boot, and a wet winter turns it to paste on the mats. The shampoo and extraction in the Full Interior Detail lifts it out of the fibres; a vacuum alone grinds it in. The market town's terraces park at the kerb, which is fine, because the washer brings the power.
Leaf litter and pollen. The garden city's trees get into the car as much as onto it, through the vents and on shoes, and by October the carpets of a Letchworth car are a compost heap in miniature. The Deluxe Interior every couple of months is the garden city habit; the Full Interior Detail in spring resets it.
Hatfield has a university and the cars of students, parents and lecturers, which means fast food, a term's receipts and a lot of miles on the A1(M); Welwyn Garden City has the county's leafiest streets and the damp that goes with them. The Full Interior Detail for the term's end, the Deluxe Interior for the commuter.
River damp. A car that lives between the Lea and the A10 fogs its windows every winter morning and smells faintly of the river by February. Steam is the answer because it lifts the damp out of the fabric rather than perfuming it, and the protectant slows it returning. A morning window, so the shampooed carpets dry through the afternoon.
Dogs and commuters. The avenues of Harpenden and Marshalswick run the county's newest cars and some of its oldest dogs, and the station run adds coffee and a week of newspapers to the mix. The Full Interior Detail with the hair properly lifted from the seats and the boot; the Essential Interior in between for the quick tidy.
Mud. Knebworth, Datchworth, Codicote, Whitwell and Kimpton are footwell country: the walks, the horses, the muddy children and the boot that has never been fully empty. This is the Full Interior Detail's natural home, and it comes to the drive with its own water and power.
Across the county
Hertfordshire grits around 1,500 miles of priority roads from October to the end of April, and the salt gets inside every car in the county on wet shoes, drying into pale tide marks on the mats and the carpet under the pedals. A vacuum spreads it. A shampoo and steam lifts it, which is why April is the month for the Full Interior Detail, and September the month for the second one, after the summer's sand and grass and before the salt comes back. The clocks went back on 25 October; an interior clean does not need daylight, but the carpets dry faster in a morning window.
To book, type the postcode into the booking page, confirm a Network washer covers it, pick the Full Interior Detail or the Deluxe Interior and a window, and unlock the car when the washer arrives. For a car that has gone a year or more without care, with food, mud and dog all in it, the Deep Clean goes further and takes two slots. For a car about to go back to a lease company, the end of lease page is the one to read, because the inside is half the inspection.
