How to Steam Clean Car Upholstery Seats (Full Process Video)
One of the most common questions we get is how to properly clean upholstery seats in a vehicle. While there are many different methods out there, the process shown below is the exact approach we use every day—and it has proven time and time again to be one of the most effective ways to deep clean automotive interiors.
In the video below, you’ll see the full process in action. While the video focuses more on the cleaning itself than the final “after,” the results were a dramatic improvement once the job was complete. This method has been used thousands of times and consistently delivers strong results when it comes to removing dirt, grime, and stains from upholstery.

The video at the bottom of this page shows exactly how steam cleaning and extraction work together. You’ll be able to see how the steam breaks down contamination and how the extractor removes it from deep within the fabric. This gives a clear, real-world look at what’s happening beneath the surface of the seat.
Why Steam Cleaning Upholstery Works So Well
Upholstery seats are highly porous, which means they absorb dirt, spills, and oils very easily. Over time, these contaminants become embedded deep within the fibers, making them difficult to remove with basic cleaning methods.
Steam cleaning is effective because it uses high heat to break down and loosen that embedded contamination. When combined with the proper tools and technique, it allows for a much deeper clean than traditional methods.
Step 1: Pre-Treating the Upholstery
The process begins with a light application of carpet and upholstery shampoo. Only a small amount of product is needed, as the steam will do most of the heavy lifting.
A quality automotive upholstery cleaner is designed to break down dirt and oils without leaving the fibers stiff or sticky. Many professional-grade products also contain optical brighteners, which help restore the appearance of carpets and fabric surfaces.
Allowing the cleaner to sit briefly on the surface helps loosen the contamination before steam is applied.
Step 2: Steam Cleaning and Agitation
Once the pre-treatment has had time to dwell, steam cleaning begins.
Using a vapor steamer that produces temperatures around 310–320 degrees, steam is applied directly to the upholstery. A triangular brush attachment is used at the same time to agitate the surface, helping lift dirt and grime from deep within the fibers.
The steam does not remove the contamination by itself—it breaks it down and brings it to the surface. This is what prepares the seat for the next step in the process.
Step 3: Hot Water Extraction
After steam cleaning, extraction is what truly completes the job.
Using a heated extractor such as the Mytee HP60 Heated Carpet Extractor, hot water is injected into the upholstery and immediately vacuumed back out. This process removes the dirt, grime, and cleaning solution from deep within the fabric.
With high water pressure, strong suction, and heated water, the extractor is able to pull out contamination that would otherwise remain trapped in the seat.
Why Steam and Extraction Work Together
Steam cleaning and extraction are most effective when used together as a system.
Steam loosens and lifts the contamination, while extraction removes it completely. Without extraction, the dirt would remain in the upholstery even if the surface appears cleaner.
This combination is what creates the noticeable improvement seen in the video.
Real Results from the Process
Even though the video focuses primarily on the process, the final results were a significant improvement. The seats looked cleaner, fresher, and much more uniform in appearance.
It’s important to understand that results can vary depending on the type and age of the stain. Some stains may not be completely removable, but the overall improvement is often dramatic.
What the Extraction Process Reveals
One of the most surprising parts of this process is what comes out of the upholstery.
The recovery tank from the extractor often fills with dark, dirty water, showing just how much contamination was hidden beneath the surface. This is something that most people never see, but it highlights how important deep cleaning really is.
How This Fits Into Complete Vehicle Care
Interior cleaning plays a major role in maintaining your vehicle, but protecting the exterior is just as important.
For long-term protection, combining interior care with exterior protection is the best approach. Applying a ceramic coating helps protect your paint and makes maintenance easier, while paint protection film installation provides added protection against rock chips, scratches, and environmental damage.
Final Thoughts
Steam cleaning combined with hot water extraction is one of the most effective ways to clean car upholstery seats. It goes far beyond surface cleaning and removes contamination from deep within the fabric.
If you want to see exactly how this process works, the video above provides a clear, real-world demonstration of the results you can expect.
