Interior Detailing Guide: Professional Process Explained

Your car's interior takes a beating. Coffee spills, food crumbs, sun damage, body oils on the steering wheel, dust in every crevice.

Regular vacuuming helps, but professional interior detailing transforms a cabin—restoring that new-car feeling and extending the life of interior surfaces.

Here's exactly how we do it.

What Professional Interior Detailing Includes

A full interior detail typically covers:

• Deep vacuuming (seats, carpet, trunk)
• All surfaces cleaned (dash, console, doors)
• Leather cleaned and conditioned
• Fabric shampooed or extracted
• Glass cleaned (inside and out)
• Vents and crevices detailed
• Plastics protected
• Odor elimination
• Final inspection

Time required: 2–5 hours depending on vehicle size and condition

The Professional Process

Step 1: Remove and Assess

Before cleaning:

Remove everything:

• Floor mats
• Trash
• Personal items
• Removable cup holders/ashtrays

Assess condition:

• Note stains requiring extra attention
• Identify material types (leather, vinyl, fabric)
• Check for damage or wear

This prevents surprises and ensures nothing gets damaged.

Step 2: Blow Out and Vacuum

Compressed air first: We use compressed air to blow debris from:

• Air vents
• Seat crevices
• Between console and seats
• Under seat rails

This loosens embedded dirt before vacuuming.

Thorough vacuuming:

• All seats (move forward and back to access rails)
• Carpet and floor areas
• Trunk/cargo area
• Door pockets and storage areas
• Headliner (gentle brush attachment)

Pro tip: Agitate carpet with a stiff brush before vacuuming to lift embedded dirt.

Step 3: Clean Hard Surfaces

Dashboard and console:

1. Apply all-purpose interior cleaner to microfiber cloth
2. Wipe all surfaces including buttons and knobs
3. Use detailing brush for textured areas
4. Buff dry with clean microfiber

Steering wheel: High-touch area requiring careful attention:

1. Use pH-neutral cleaner (leather or vinyl specific)
2. Gently scrub with soft brush
3. Wipe completely dry for safe grip
4. Condition if leather

Door panels:

1. Wipe handles, armrests, map pockets
2. Clean window switches and controls
3. Wipe door jambs (often forgotten)

Center console:

1. Clean cup holders (often worst area)
2. Clean gear selector area
3. Clean storage compartments
4. Screen cleaning with appropriate product

Step 4: Clean Seats

Leather seats:

1. Vacuum to remove debris
2. Apply leather cleaner
3. Agitate with soft horsehair brush
4. Wipe clean with damp microfiber
5. Allow to dry
6. Apply leather conditioner
7. Buff to finish

Fabric seats:

1. Vacuum thoroughly
2. Pre-treat stains if needed
3. Apply carpet/upholstery cleaner
4. Agitate with upholstery brush
5. Extract with hot water extractor
6. Allow to dry completely

Common stain treatments:

Step 5: Clean Carpet and Floor Mats

Carpet:

1. Vacuum thoroughly
2. Apply carpet cleaner
3. Agitate with stiff brush
4. Extract with hot water extractor
5. Allow to dry before driving

Floor mats:

Rubber/plastic:

1. Remove from vehicle
2. Pressure wash or scrub with brush
3. Apply all-purpose cleaner
4. Rinse and hang dry

Carpet mats:

1. Vacuum both sides
2. Shampoo and extract
3. Hang to dry completely

Step 6: Clean Glass

Interior glass collects film from:

• Off-gassing of plastics
• Smoke residue
• Touch marks
• Cleaning product overspray

Proper glass cleaning:

1. Use ammonia-free glass cleaner
2. Clean with waffle-weave microfiber
3. First pass horizontal, second pass vertical
4. Check for streaks in direct light
5. Don't forget rearview mirror

Windshield tip: The inside of the windshield is often the dirtiest. Take extra time here.

Step 7: Final Touches

Protect surfaces: Apply interior protectant to:

• Dashboard (matte finish protectant)
• Door panels
• Center console
• Vinyl/rubber surfaces

Choose finish level:

• Matte/satin for modern look
• Semi-gloss for moderate sheen
• Avoid high-gloss (looks artificial)

Air freshener (optional):

• Avoid overpowering scents
• Under-seat options last longer
• Ozone treatment for severe odors

Dealing with Odors

Common Odor Sources

Ozone Treatment

For severe odors, ozone generators:

• Kill odor-causing bacteria
• Neutralize smoke particles
• Eliminate musty smells
• Treat areas cleaning can't reach

Caution: Ozone is harmful to breathe. Vehicle must be unoccupied during treatment and ventilated after.
