How to Clean Car Seats Like a Professional Detailer

The Correct Way to Clean Cloth Car Seats Deep Down

Quick Summary
Most spray fabric cleaners don’t do a good job on cloth car seats — to clean them properly, you need to go deeper than just cleaning the cloth, you need to pull out the stains embedded in the foam padding. To do that, you can rent a carpet/upholstery extraction cleaner. Follow these steps:

1) Disconnect the car battery to prevent power drain and avoid accidental damage to seat airbags or heating elements.
2) Vacuum the seats using a crevice tool to remove loose dirt, crumbs, and debris from seams and cracks.
3) Apply a dedicated upholstery cleaner or dish soap and warm water to visible stains, letting it sit a few minutes to break down the stain.
4) Scrub the entire seat surface with a stiff-bristled brush in circular motions to work the cleaner into the fabric and lift embedded dirt.
5) Rent an extraction carpet and upholstery shampooer to clean not just the cloth, but the foam beneath the seat cover.
6) Use a wet-dry vacuum or dry microfiber towels to extract as much moisture as possible before allowing the seats to fully air dry.
7) Finish by leaving the car doors open or running the ventilation system to allow the seats to air dry completely — this last step is crucial to prevent mold and mildew from developing in the damp fabric.

Extracting Hidden Dirt from Car Seats

Whether you’re trying to clean cloth car seats that are stained and dingy the real secret is simple: you’ve got to clean not only the cloth, but also remove the stains embedded in the foam under the seat covers. Keep in mind that the foam is what absorbs sweat, body oils, spilled drinks, rainwater, and dirt tracked in from your clothes. To do that, you’ll need a carpet/upholstery extraction cleaner, along with stain removers and upholstery cleaner.

When I clean cloth car seats, I treat them like automotive carpet—because that’s essentially what they are. Fabric over foam. And that foam absorbs everything: sweat, body oils, spilled drinks, rainwater, and dirt tracked in from your clothes.

Disconnect the battery

You’ll be using water, cleaners, stain removers on the seat covers and the foam cushions. To avoid shocking mistakes, disconnect the battery before you start.

Start by vacuuming with a wet/dry shop vac

Not with a wimpy power plug vacuum,

but with your shop vac and crevice tools. The first step to properly clean cloth car seats is always vacuuming. Pay attention to the grit in the seams and stitching. Use a nylon bristle brush to loosen embedded dirt before vacuuming it away. If you skip this step, you’re just grinding grit deeper into the fabric when you start scrubbing.

Pre-treat the stains

Purchase a spray can of automotive upholstery clean and spray the dirties spots to give them a head start before the shampoo/extraction procedure. Agitation is critical. Use a soft brush and work the cleaner into the fibers. This breaks up oils and lifts grime trapped in the material.

Shampoo and Extract

This is what separates the amateurs from the pros. If you really want to clean cloth car seats thoroughly,

use a carpet/upholstery shamooer and extractor. The shampooer sprays pressurized water/soap into the fibers and then into the foam, because that’s where the stains live. Then the extractor pulls out the water/soap solution, along with the embedded dirt and stains. Watch the recovery tank on the extractor and you’ll see how much dirt comes out. It’s shocking!

Next, remix new cleaning solution, cutting the amount of detergent by 75%. This will be a partial repeat cleaning/rinsing operation. Again, watch the recovery tank and you’ll see less dirt on this cycle.

Finally, repeat the entire operation with plain rinse water. This step will remove any remaining detergent from the fabrin and the foam.

Vacuum again

The extractor does a good job of pulling out the dirt and water. But your wet/dry shop vac does an even better job. Plus, it helps the seats dry faster.

Leave the doors open to dry out

Set a small fan in the car to move air around while the seats dry.
