LIQUI MOLY Pro-Line Throttle Valve Cleaner is a specialized solution designed to effectively clean throttle valves and throttle bodies, ensuring optimal engine performance and efficiency.

In the intricate ecosystem of an engine, even the smallest components can have a significant impact on performance. The throttle valve, responsible for regulating airflow into the engine, is no exception.


  1. Powerful Cleaning Action: LIQUI MOLY Pro-Line Throttle Valve Cleaner is formulated with a potent cleaning agent that effectively dissolves and removes carbon deposits, varnish, and other contaminants from throttle valves and throttle bodies.
  2. Throttle-Specific Formula: Engineered specifically for throttle components, this cleaner spray is designed to penetrate and dislodge stubborn deposits that can accumulate over time, leading to reduced airflow and impaired engine performance.

  4. Safe for Sensors and Electronics: Unlike some aggressive cleaners that can harm electronic components, this throttle valve cleaner is safe to use on throttle position sensors, idle control valves, and other electronic components commonly found in modern engine systems.
  5. Versatile Application: In addition to throttle valves and throttle bodies, LIQUI MOLY Pro-Line Throttle Valve Cleaner can also be used to clean intake manifolds, EGR valves, and other related components, making it a versatile solution for engine maintenance.


  1. Restored Engine Performance: By effectively removing carbon deposits and varnish buildup from throttle valves, this cleaner restores proper airflow and throttle response, resulting in improved engine performance, smoother idling, and enhanced drivability.
  2. Fuel Efficiency: A clean throttle valve ensures optimal airflow into the engine, promoting more efficient combustion and fuel utilization. Regular use of LIQUI MOLY Pro-Line Throttle Valve Cleaner can help improve fuel efficiency and reduce emissions over time.
  3. Preventive Maintenance: Cleaning throttle valves and throttle bodies regularly with this specialized cleaner helps prevent the accumulation of harmful deposits, extending the lifespan of engine components and minimizing the risk of performance issues or costly repairs down the line.
  4. Reduced Emissions: Cleaner throttle components contribute to more complete combustion and reduced engine emissions, making LIQUI MOLY Pro-Line Throttle Valve Cleaner an eco-friendly choice for vehicle owners concerned about their environmental impact.

How to Use LIQUI MOLY Pro-Line Throttle Valve Cleaner

  1. Preparation: Ensure that the engine is turned off and cool before starting the cleaning process. Disconnect the air intake hose to access the throttle valve or throttle body.
  2. Spray Application: Shake the canister well before use. Hold the spray can approximately 10-15 cm away from the throttle valve or throttle body and apply the cleaner liberally, targeting areas with visible carbon deposits and contaminants.
  3. Allow Soaking: Allow the cleaner to penetrate and dissolve the deposits for a few minutes. This will help loosen stubborn buildup and make it easier to remove during the cleaning process.
  4. Mechanical Agitation: Use a soft-bristled brush or cloth to gently scrub the throttle valve and surrounding areas, helping to dislodge any remaining deposits and ensure thorough cleaning.
  5. Repeat if Necessary: For heavily soiled throttle valves or stubborn deposits, repeat the spraying and scrubbing process as needed until the surfaces are clean and free of residue.
  6. Final Inspection: Once the cleaning process is complete, visually inspect the throttle valve and throttle body to ensure that they are thoroughly cleaned and free from any remaining deposits or contaminants.
  7. Reassembly: Reconnect the air intake hose and any other disconnected components, ensuring that all connections are secure and properly tightened.
  8. Testing: Start the engine and check for smooth idling and responsive throttle response. Perform a brief test drive to ensure that the engine operates smoothly and efficiently after cleaning.

To prepare, attach a tube with a nozzle. To gain access, remove the hose or pipe immediately before throttle housing. The engine needs to run to perform cleaning. If unable to start the engine, disconnect the air mass sensor connector while the ignition switch is in the off position. Maintain a minimum engine speed of 2000 rpm while spraying cleaner in short intervals of 2-3 seconds, and at the same time move the nozzle back and forth across the opening to completely treat the intake tract. If engine speed fluctuates more than 1000 rpm stop spraying immediately and wait for speed to stabilize. Keep cleaning fluid from contacting air mass meters or painted surfaces. If excess deposits inside the EGR valve, intake manifold, or intake valves, a second can of cleaner may be used to improve the result. After completion, leave the engine running at 2000 rpm for a minimum of 20 seconds to allow complete removal of any residing fluid in the intake system. Afterward, erase any stored fault codes.
