Car detailing glossary

Detailing has a lot of jargon. Here is what the common terms mean, and which of them NOVA actually does.

Terms A to Z

Add-on
An extra you can add to a package. NOVA's add-ons are the engine bay detail and spot buffing.
Ceramic coating
A hard, long-lasting protective layer bonded to paint after polishing. We don't offer it.
Clay bar
A clay tool used to lift bonded contamination from paint. We don't sell clay bar treatment as a separate service.
Decontamination (paint)
Removing contamination that washing leaves bonded to the paint, such as tar, sap residue or iron particles. It cleans the surface; it does not polish or remove scratches. Part of Elite Restoration.
Detail vs wash
A wash removes loose dirt. A detail is a careful, surface-by-surface clean, inside and out, done by hand.
Dye transfer
Color from clothing, usually new denim, that rubs onto light seats. Easier to remove while fresh.
Engine bay detail
Cleaning a cool engine bay with the air intake and exposed electrical parts covered, using low-pressure water, steam or wipe-down. On EVs it means a wipe-down of the front trunk and visible plastic covers.
Extraction (hot-water)
Spraying hot water into carpet or cloth and vacuuming it back out to lift dirt and many stains. Leaves fabric damp for several hours.
Front trunk (frunk)
The storage space under the hood of many EVs. We clean it like the interior.
Hand wash
Washing the car by hand with mitts and towels instead of machine brushes.
Paint correction
Machine polishing whole panels or the whole car in several steps to remove swirls and scratches. We don't offer full paint correction.
Paint protection film (PPF)
A clear film applied over paint to resist chips. We don't install it.
Paint sealant
A synthetic protective product applied to paint. We don't offer it as a service.
Piano black trim
Glossy black interior or exterior trim. It scratches very easily, even with gentle cleaning.
Rinseless wash
Washing with a high-lubrication solution and towels, without a hose rinse. Useful in garages and where water should not run off.
Spot buffing
Machine polishing of small areas you approve, to reduce light marks. Included in the Complete Detail.
Swirl marks
Fine circular scratches in the clear coat, often from rubbing grit into paint or from brush washes. Most visible on dark paint in sunlight.
Tire dressing
A product that gives clean tires an even, dark finish. Part of the Exterior Detail.
Trim restore
Cleaning and refreshing faded exterior plastic trim. Part of Elite Restoration.
Walkaround
Our check of the car and work area before we start, with photos of existing condition.
Waterless wash
Cleaning light dirt with a spray product and microfiber towels and no water. Best for lightly dusty cars.
Water spots
Mineral marks left when water dries on paint or glass. Fresh spots usually wipe away; etched spots may not.
