What snow foam, clay bar, iron fallout and ceramic coating actually mean, and which of them are part of a Gleam N Clean detail in East London.
Car detailing has a vocabulary problem. A quote mentions snow foam, decontamination, clay bar and sealant, and it is rarely clear which of those is a real extra step and which is just a nicer word for washing a car. This page is the answer we give in person: every term below is one that comes up during a detail in East London, written in plain English, with a line on why it matters to you rather than to a detailer.
The short version is that valeting and detailing are different sizes of job. A valet washes a car and tidies the inside. A detail treats the paint first, so nothing is scratched on the way, then cleans into the places a vacuum does not reach, and finally applies protection so the result lasts more than a weekend. Most of the terms on this page belong to that last part: removing what a wash leaves behind (brake dust, tar, tree sap) and then sealing the surface so it stays clean for longer.
Two things worth knowing before you read on. Fine scratches in paint, called swirl marks, are not dirt and no wash removes them: that is paint correction, a separate machine-polished job quoted after the paint is inspected. And water matters: a mobile detail uses the tap at your address, so the car is dried properly rather than left to air dry and spot.

A valet is a clean: a wash, wheels and tyres, glass, a vacuum and a tidy of the interior. It makes a car look cared for again, but it is not trying to remove anything from the paint itself.
Why it matters: If you only need the car to look good for the week ahead, a valet is the right size of job. A detail goes further and lasts longer.
Detailing is a slower, deeper version of the same job. Contaminants are removed from the paint before anything touches it, the interior is cleaned into seams, vents and rails, and protection is applied at the end so the finish holds.
Why it matters: Both Gleam N Clean packages are details rather than valets: the paint and interior are decontaminated, then protected.
A thick pre-wash foam sprayed over the whole car and left to dwell for a few minutes, so it softens and lifts road film before any mitt or sponge touches the paint.
Why it matters: Most fine scratches come from dragging dirt across paint. The foam takes the bulk of that dirt off first, without contact.
Washing from two buckets — one with shampoo, one with clean rinse water, each with a grit guard at the bottom. The wash mitt is rinsed between panels so grit sinks to the bottom instead of going back onto the car.
Why it matters: It is the cheapest way to avoid putting the dirt you just removed straight back onto the paint.
The stage where a soft microfibre mitt and shampoo actually touch the car, done a panel at a time and always from the top down so the dirtiest areas are last.
Why it matters: It is the part of the wash that carries the most risk, which is why the car is foamed and the wheels are done first.
An acid-free liquid that reacts with tiny ferrous particles — mostly brake dust — embedded in paint and wheels. It dissolves them and turns purple as it works, which is how you see what the wash left behind.
Why it matters: Brake dust is sharp and rusts. Left in the paint it turns into small brown spots that a normal wash will not shift.
A solvent that softens sticky bitumen spots so they wipe away instead of being scraped off, used on lower doors, sills and wheel arches.
Why it matters: Common on cars that park near roadworks or use the A13 and North Circular regularly.
A soft clay bar, kept wet with a lubricating spray, glided over clean paint to pull off bonded contamination a wash cannot shift — tree sap, industrial fallout and overspray. The paint should feel like glass afterwards.
Why it matters: Grit in the air around East London bonds to paint. Until it is removed, no sealant can sit flat on the surface.
Very fine circular scratches in the clear coat, usually caused by washing or drying with a dirty, dry or gritty cloth. They are invisible in shade and obvious in direct sunlight.
Why it matters: They are not dirt, so no wash removes them. Only machine polishing does — see paint correction below.
Machine polishing that levels a thin layer of clear coat to remove swirl marks, light scratches and oxidation. It changes the paint, not just the dirt on it, and is quoted per car after the paint is inspected.
Why it matters: It is a separate job. Cleaning and protection is what the two packages cover; correction is arranged on its own when the paint needs it.
Pale ring marks left when water is allowed to dry on paint or glass, most common with the hard water that comes out of an outside tap.
Why it matters: Mobile detailing uses the tap at your address, so the car is dried properly rather than left to air dry.
A synthetic liquid protection applied to clean paint and glass. It adds a slick layer that repels water and makes the next wash easier, and typically lasts from a few weeks to a few months.
Why it matters: A sealant is applied as the last step of both packages, which is why the car stays cleaner for longer afterwards.
A semi-permanent, glass-like layer bonded to the paint that repels water and dirt for a year or more. It has to go onto clean paint, and usually onto corrected paint, to sit properly.
Why it matters: A coating applied over contamination traps it. It is a separate service, quoted after the paint is seen.
Pressurised steam used on fabrics, plastics, vents and seat rails to lift dirt and neutralise bacteria while using very little water.
Why it matters: The Deep Clean uses steam inside, which is why it reaches vents, stitching and rails rather than just the carpet surface.
A gel applied to the sidewall after washing that restores a deep black finish and shields the rubber from sunlight.
Why it matters: It is the finishing step on the wheels, and it is what makes a freshly cleaned car look finished rather than just washed.
A foam pre-wash, a safe two-bucket contact wash, wheels, tyres and glass, an interior vacuum and wipe down, and a sealant at the end. It keeps a clean car clean.
What each package coversEverything above, plus iron fallout removal, tar removal, a clay bar over the paint and glass, steam cleaning inside, and the sealant applied to properly decontaminated paint.
