Choosing a professional car interior cleaning service


When it comes to professional car interior cleaning, it’s important to be mindful of the type of service to choose. There are various services available, but how do you know which one is the best for your needs? Here are the factors to consider when selecting a professional cleaning service:

Professional steam cleaning for car interiorsReputation

Look for a professional with a good reputation in the industry. Read customer reviews and check if they have experience in cleaning car interiors. It’s even better if the profile provides content and photos of services performed on other vehicles.

Technologies and products

Ensure that the professional uses high-quality specific equipment and products. DettaglioAuto has been using steam for over 15 years for car interior cleaning, coupled with our Interior Cleaner, a specific biodegradable detergent. Steam is delivered with the detergent through the 09EVO machinery specifically designed for this purpose. According to us, steam usage is the most effective cleaning method. Thanks to the high steam temperature combined with the specific detergent, Interior Cleaner, it can penetrate deeply into any surface, loosening and removing dirt through the 09EVO machinery’s extraction function. This process eliminates stubborn stains and renews surfaces. Moreover, it allows the removal of unpleasant odors such as smoke, mold, and animals.

This innovative technique achieves unparalleled results without soaking the interiors, reducing the risk of mold proliferation and long drying times.

Services offered

Check the services included in the professional cleaning package. A good professional car interior cleaning service should include a well-detailed list of all the steps in the service. It should include:

  • Cleaning all surfaces and materials in every interior compartment of the cabin.
  • A certified sanitization that ensures a real reduction of microbial load.
  • Treatment of surfaces with specific cosmetic products for each material, such as leather and plastics, to preserve the obtained result over time.

Service timing

The service duration can range from half a day to a full day. Professional car interior cleaning requires a detailed job aiming for a real “renovation” of the interiors. That’s why DettaglioAuto calls its service “Rinnovamento Interni” (Interior Renewal). Our goal is to deliver to the customer a clean, sanitized, and renewed car, as if it were new, just out of the dealership.


The cost of the service is not comparable to that of a traditional car wash, as seen in service stations or mall parking lots. It’s important not to compare these two types of services.

How to recognize a real car sanitization service?

In recent years, the term “sanitization,” even in our car detailing and car wash sector, has been widely used, especially since the emergence of the COVID problem. The term “sanitization” has sometimes been improperly exploited and solely for marketing purposes.
Car interior sanitization

Here are some important concepts to keep in mind to understand when a car interior cleaning service performs certified sanitization:

  • It’s not sanitization when spray cans are used, promising the elimination of all bacteria in the cabin.
  • Solely using ozone does not constitute complete sanitization; ozone is effective when combined with steam. This is because the elevated temperature of steam is primarily responsible for killing most microorganisms.
  • Finally, when you approach a company for interior sanitization of your car, you can request a certificate or a test report on their sanitization method, preferably issued by a recognized third-party entity, attesting to its real effectiveness. In this way, you can be sure that the service will guarantee an effective reduction of microbial load.

DettaglioAuto had its interior renewal service tested in 2017, before COVID era,  by an Accredia-certified laboratory, showcasing the before-and-after of our steam cleaning method associated with our biodegradable detergent. The treatment was carried out inside a Ford Fiesta never before treated with steam, using our professional car interior cleaning procedure. The result confirms the effectiveness of our Interior Renewal service and, therefore, the effectiveness of our procedures. In addition to effective sanitization, we achieve a real aesthetic renewal of the interiors.

Factors affecting the cost of professional car interior cleaning

Car interiors disassembled without seats for professional interior cleaningThe cost of professional car interior cleaning can vary depending on several factors. Here are the two main factors influencing the service cost:

  • Car Size: Larger cars require more time and resources to be cleaned, so the cost will generally be higher.
  • Interior Conditions: If the interiors are particularly dirty and present challenging situations such as animal hairs, specific stains, sand, mud, liquid spills (e.g., oil), more time and therefore more labor are required. In some cases of substantial dirt, it may be necessary to disassemble the seats to clean more effectively.


How much does professional car interior cleaning cost?

DettaglioAuto offers its Interior Renewal service at a cost starting from €250.

The cost may seem high, but it’s essential to consider that the service is performed by qualified technicians and may require an entire working day, ranging from a minimum of 4 hours to a maximum of 8 hours. At the end of the service, the customer receives a sanitized and renewed car as if it were just picked up from the dealership.

Benefits of professional car interior cleaning

Now that you have an understanding of the involved steps and factors influencing the cost, it’s crucial to evaluate the benefits of professional car interior cleaning. Here are some of the main advantages:

  1. Impeccable Appearance: Professional car interior cleaning will make the inside of your vehicle look like new by removing stains, dirt, unpleasant odors, and renewing the internal materials. Over the years, the accumulation of dirt, chemicals, and normal weathering has likely altered the original appearance of the interiors. If your used car has never undergone this type of treatment, you might rediscover the satisfaction of seeing it brought back to new.
  2. Sanitization: DettaglioAuto’s steam cleaning can eliminate bacteria and germs in the cabin, creating a healthier and more hygienic environment for you and your passengers. This is particularly important when purchasing a used vehicle, as many users wish to perform genuine sanitization.
  3. Preventing Surface Deterioration: Professional car interior cleaning helps maintain the condition of materials, such as leather seats or plastic surfaces, preventing wear and surface deterioration. This way, even the car’s interiors, if kept in excellent condition, help preserve the vehicle’s market value over time.
  4. Increased Comfort: With clean and fresh interiors, you can enjoy a more pleasant and comfortable driving experience, with passengers also noticing the increased comfort.

Comparison between professional car interior cleaning and a car wash service

You may wonder if it’s worth investing in professional car interior cleaning compared to a traditional wash. Here’s a comparison between the two:

Cleaning level:

A professional steam car interior cleaning service offers a high standard of cleanliness. Thanks to steam, every compartment and crevice of the car can be reached, down to the smallest detail. The same result is difficult to achieve with a dry wash relying on chemical products, while a water wash could saturate the cabin too much, especially the upholstery, with the risk of finding stains once the materials have completely dried.

Stain removal:

Professional cleaning through steam and suction can remove persistent stains that may not be eliminated with a traditional wash. Stain removal with chemical products could be too invasive on certain types of delicate materials, and it should be noted that chemical use would require rinsing to avoid leaving residues on the treated surface.


Professional cleaning can guarantee effective sanitization of the car’s interiors. Our combination of a complete ozone cycle, steam, and biodegradable detergent ensures effective reduction of microbial load on surfaces, as demonstrated in our certification.

Duration of results:

The results of professional car interior cleaning last longer compared to a traditional wash. The car will remain fresh and clean for a longer period. Maintaining cleanliness through express cleaning interventions, always carried out by your trusted professional, will protect the materials from normal deterioration over time.

How often to repeat the service and how to maintain it?

The frequency with which you should repeat the professional car interior cleaning service depends on the vehicle’s use and conditions.

DettaglioAuto recommends its customers who have undergone the Interior Renewal service to maintain it once every two or three months through our Express Exterior Wash service, which not only guarantees a professional exterior wash but also includes complimentary general interior cleaning. It’s also recommended to repeat the Interior Renewal service 1 or a maximum of 2 times a year, depending on the type and frequency of vehicle use.

Conclusion: Is it worth investing in professional car interior cleaning?

After examining the costs, service steps, and benefits of professional car interior cleaning, the question remains: is it worth investing in this service?

The answer depends on your needs, expectations, and the value you attribute to the cleanliness and appearance of your car. If you want to keep your car in impeccable condition, investing in a professional car interior cleaning service can be a smart choice. After all, the car is a means of transportation on which we spend many hours of our lives, and therefore, if the cabin is healthy, it’s already a significant plus. Additionally, the car reflects our personality and image to those who board as passengers.
