Fuel injector cleaners are a great way to keep your car's fuel injectors in good condition, but will they clean your throttle body, too? The short answer is no — fuel injector cleaner will not clean your throttle body. To clean your throttle body, you'll need to use a throttle body cleaner and a rag or a can of carb/throttle body cleaner. Some people also recommend using a small amount of NAPA TB cleaner with a rag. It's also worth noting that fuel-injected vehicles rarely experience carbon build-up in the throttle body, so you may not need to worry about cleaning it at all. However, if you do decide to clean your throttle body, it's important to be careful as it can be a messy process.

What You'll Learn
Fuel injector cleaner will not clean throttle body
It is a common misconception that a fuel injector cleaner will also clean your throttle body. However, this is not the case. Fuel injector cleaners are designed to be added to the fuel tank, and while they can effectively clean fuel injectors and intake valves, they do not clean the throttle body.
The throttle body is a critical component of an engine, and it requires periodic cleaning to maintain optimal performance. Over time, carbon deposits and other contaminants can build up on the throttle body, leading to reduced engine performance and fuel efficiency. Therefore, it is essential to use the correct cleaning products and methods specifically designed for the throttle body.
One effective way to clean the throttle body is to use a dedicated throttle body cleaner spray. These sprays are designed to remove carbon buildup and other contaminants from the throttle body and related components. They can be applied directly to the throttle body and wiped clean with a rag. It is recommended to clean the throttle body periodically, depending on the vehicle's usage and operating conditions.
Additionally, some people suggest using a catch can to prevent the throttle body from loading up with carbon deposits and other contaminants. A catch can is a device that is installed in the engine's ventilation system and helps to separate and capture oil and other contaminants before they reach the throttle body. This can help to reduce the frequency of throttle body cleaning and maintain optimal engine performance.
It is important to note that while fuel injector cleaners are not effective for cleaning the throttle body, they are still beneficial for maintaining fuel injectors and intake valves. Therefore, it is recommended to use dedicated cleaning products and follow proper maintenance procedures for each specific component of the engine to ensure optimal performance and longevity.

Walnut shells can be used to clean throttle bodies
Walnut shells are an effective and safe way to remove carbon deposits without damaging the metal of the intake manifold and valves. The shells are softer than the metal but hard enough to remove the deposits. The granules hit the carbon at high speed, entirely removing the build-up. This process can also be done at home with a media blasting kit, although it is important to prepare the kit and cover the engine bay to catch any loose walnuts.
Walnut blasting offers several benefits for your car. After cleaning, you can expect a smoother idle, lower fuel consumption, a smoother throttle response, and even additional horsepower gains. It is a safe and effective method to remove carbon deposits and improve the performance of your vehicle.
While walnut blasting is a popular method for cleaning intake manifolds and valves, it is important to note that it may not be suitable for all vehicles. The process of removing components to access the intake manifold may vary depending on the car's make and model. Additionally, cleaning the throttle body may not be necessary for all vehicles, especially fuel-injected cars, as the fuel injector's position keeps the area constantly cleaned.

Fuel additives may not be strong enough to clean throttle bodies
In addition, fuel additives may not be able to remove thick carbon buildup in the throttle body, which can cause drivability issues. The best way to clean this is to use a sandblaster filled with walnut shells, as they are abrasive enough to remove the carbon without damaging the metal.
Furthermore, fuel additives may not be able to clean the intake runners/intake ports on the head of a direct injection engine, which can also experience carbon buildup. Cleaning these areas requires more than just adding an additive to the tank or spraying a cleaner into the intake.
While some fuel treatment options are available, such as the one offered for a Merc GLC 300, they may not be effective enough to justify the cost. It is often recommended to simply clean the throttle body manually, which can be easily done by popping it off and cleaning it with a can of carb/throttle body cleaner. As such, fuel additives may not be the best option for cleaning throttle bodies, and other methods may be more effective.

Fuel injectors can be cleaned with Chevron Techron or Gumout Regane
Chevron Techron is a well-known and trusted brand in the automotive industry, and their Techron Concentrate Plus is recommended by many major automakers worldwide. It is suitable for use in all carbureted, fuel-injected spark ignition, and gasoline direct injection engines, but it is not recommended for diesel engines. The product is available in different package sizes, including 6-12 oz bottles, 6-20 oz bottles, and 6-32 oz bottles.
Gumout Regane is another popular choice for fuel injector cleaning. It is designed to remove deposits and build-up from fuel injectors, improving engine performance and fuel efficiency. Gumout Regane is safe to use on most types of engines, including diesel and gasoline engines. It is available in a range of sizes to meet the needs of various vehicles.
Using a fuel injector cleaner is an important part of maintaining the performance and fuel efficiency of your vehicle. Over time, fuel injectors can become clogged with deposits and build-up, which can inhibit fuel flow and cause engine hesitation. By using a fuel injector cleaner regularly, you can help prevent these issues and keep your fuel injectors in optimal condition.
In addition to using a fuel injector cleaner, it is also important to note that the throttle body may require separate cleaning. While the fuel injector sits behind the intake ports on the cylinder head, constantly cleaning that area, the throttle body may still accumulate carbon build-up that a spray cleaner cannot remove. In such cases, it is recommended to have the throttle body inspected and cleaned by a professional.

Fuel injector spray can be used to clean throttle bodies
Some people have reported using fuel injector cleaner, such as Chevron Techron or Gumout Regane, to clean their throttle bodies, but others have stated that these products did not clean the throttle body. One possible reason for this discrepancy could be the severity of the carbon build-up on the throttle body. If there is a significant amount of carbon buildup, a fuel injector spray may not be strong enough to remove it. In such cases, a more aggressive cleaning method or product may be required.
Additionally, it is important to note that the fuel injector sits behind the intake ports on the cylinder head in fuel-injected vehicles. As a result, the fuel that is sprayed into the engine constantly cleans that area, and internal cleaning is rarely needed. If there is no significant carbon buildup and the throttle body is simply due for a routine cleaning, using a fuel injector spray may be sufficient.
To effectively clean a throttle body, some people recommend using a throttle body-specific cleaner, such as a throttle body cleaning spray or a carb/throttle body cleaner. These products are designed specifically for cleaning throttle bodies and may be more effective than using a fuel injector spray. Additionally, some people have reported success cleaning throttle bodies with a rag and a small amount of TB cleaner or carb cleaner.
It is worth noting that the effectiveness of any cleaning method or product may vary depending on the specific vehicle and the severity of the carbon buildup. As such, it may be advisable to consult a trusted mechanic or automotive professional for guidance on the best cleaning approach for your particular vehicle.
