What Is Actually Included in a Full Detail

Exterior: decontamination before correction

The exterior begins with wheels and wheel wells, because they are the dirtiest part of the car and doing them last would re-contaminate everything else. Then a pre-rinse and foam to lift loose grit, followed by a contact wash using clean media and separate rinse water so grit is never dragged back across the paint.

After washing, the paint is chemically decontaminated to dissolve embedded iron particles, and clayed to shear off bonded contamination the chemicals do not reach. Only after this is the paint genuinely clean — and only then can anything be assessed or protected. Applying wax over bonded contamination seals the contamination in.

Exterior: protection

With the surface clean, a protective layer goes on: a wax, a sealant, or a ceramic coating depending on what has been agreed. Trim is dressed, tyres are dressed with a non-sling product, glass is cleaned and exterior plastics are treated.

A full detail does not automatically include paint correction. Correction is machine polishing to remove defects from the clear coat, and it is a separate, considerably longer service. Any package promising a full detail and correction in three hours is not doing correction.

Interior: the order matters

Interior work starts with removing everything loose, then compressed air and detail brushes to drive dust out of vents, seams and switchgear before vacuuming — because vacuuming first and blowing dust out second simply redistributes it.

Carpets and cloth upholstery are then shampooed and hot-water extracted, which pulls soil out of the fibre rather than pushing it deeper. Leather is cleaned with a pH-appropriate product and conditioned. Hard surfaces are cleaned and finished with a matte, non-greasy protectant — a shiny dash is a glare hazard on a bright Texas afternoon.

Glass is done last, inside and out, and it is the step most often rushed. Interior glass in San Antonio carries an outgassing film from months of heat, and it takes two passes with clean towels to actually clear.

What is usually not included

• Paint correction — separate service, separate day.
• Engine bay detailing — commonly an add-on.
• Headlight restoration — an add-on, though a valuable one.
• Odor removal treatments for smoke or mildew — these need dedicated process time.
• Pet hair beyond a light amount — heavy pet hair removal is genuinely hours of work.

How long it should take

A properly executed full detail on an average sedan in reasonable condition runs four to six hours. A large SUV or truck in poor condition can be eight or more. If someone quotes ninety minutes, they are describing a wash and vacuum — which is a legitimate service, just not this one.
