Interior Add-On, Per Seat

⚠ Deep Fabric Soiling

The Stain You Can’t See
Is Worse Than
The One You Can

Spills, food, and body oils work past the surface of a fabric seat and sit in the weave, which is why a seat can look clean and still smell. Hot-water extraction flushes that out and pulls it back up.

The Problem

What Lives Deep in Your Fabric Seats

Fabric seats are porous. Anything spilled on one works its way into the weave and stays there, out of sight but not gone.

01

Embedded Spills

Coffee, juice, soda, and food soaks through fabric instantly. The mark on top may fade, but the sugar and residue underneath keeps producing a smell long after the spill itself is forgotten.

02

Sweat & Body Oils

Every commute deposits skin oils and sweat into the seat fabric. Over months and years, this creates a deep-set yellowing and sourness that no surface wipe will remove.

03

Pet Accidents & Dander

Pet urine and accidents penetrate to the foam beneath the fabric. A surface spray never gets down to the foam, which is why the smell comes back a few days later. Extraction reaches it.

Why It Matters

Surface Cleaning Doesn’t Cut It

Spraying a fabric cleaner and wiping cleans the very top of the weave. Everything below stays exactly where it was.

Damp Fabric

Damp fabric that never fully dries out is what turns a small spill into a lasting smell. Extraction takes the organic material back out rather than sealing it in with a fragrance.

Odor at the Source

Interior odors that won’t leave despite cleaning are almost always in the fabric or foam below. Extraction reaches the source instead of masking it with fragrance.

Resale & Presentation

Stained, odorous fabric seats are among the most immediate red flags in a used vehicle inspection. Extraction restores fabric appearance and removes the smell that costs you at trade-in.

Our Process

How Seat Extraction Works

Hot-water extraction forces heated solution deep into fabric fibers, breaks up embedded soiling, and vacuums everything back out.

STEP 01

Pre-Vacuum

We vacuum the seats thoroughly to remove loose debris before the wet extraction begins. Loose debris turns to mud once it gets wet, so it comes out first.

STEP 02

Pre-Treat Stains

Visible stains receive a targeted pre-treatment with a fabric-safe stain remover. We allow appropriate dwell time before extraction begins.

STEP 03

Hot-Water Extraction

Heated water and cleaning solution are injected into the fabric and immediately vacuumed back out with strong suction. Multiple passes per seat ensure thorough cleaning.

STEP 04

Inspect & Repeat

We inspect each seat under light and repeat the extraction on any remaining stained areas. Heavy staining or pet accidents may receive a targeted enzyme treatment.

FAQ

Common Questions

Heated water and cleaning solution go into the fabric, get agitated to loosen what is embedded, and then get vacuumed back out along with the dissolved stains. It cleans down through the fabric instead of just the surface.
Typical drying time is 2 to 4 hours with windows cracked, or faster in direct sun. Leave the windows slightly open after extraction. Seats are fine to sit on once they feel damp-dry rather than wet.
Most stains respond well, including food, coffee, juice, pet accidents, and general soiling. Stains that have been heat-set may be partly permanent. We tell you what to expect before we start.
Seat extraction is for fabric and cloth seats. Leather seats need a different process, so see our Leather Cleaning and Protection service.
