Liqui Moly Pro-Line Throttle Valve Cleaner spray 400 ml — gasoline throttle & carburettor cleaner, fast-evaporating formula

LIQUI Moly Pro-Line Throttle Valve Cleaner is a professional-grade spray that quickly removes deposits, varnish and grime from throttle valves, carburettors and gasoline fuel-injection parts without disassembly.

This 400 ml workshop product is formulated for gasoline engines and designed to dissolve carbon, oil residues and other contaminants that impair throttle response and fuel metering. The spray’s solvent blend penetrates tight spaces and evaporates cleanly, allowing technicians and DIYers to restore smoother idling and throttle movement while saving time compared with full system teardown.

How does this cleaner restore throttle response?

The formula softens and lifts built-up deposits that restrict the throttle plate and bore, helping restore free movement and more consistent air flow. It reduces sticking and hesitation caused by varnish and carbon without mechanical scraping.

• Dissolves carbon, varnish and sticky fuel residues.
• Penetrates tight clearances around the throttle shaft and butterfly.
• Evaporates quickly to leave minimal residue.
• Applicable to carburettors and gasoline injection throttle bodies.

Can I use it without removing parts from the engine?

Yes — the product is intended for cleaning in place, which saves labor and reduces service time. Spray access is typically enough to reach the throttle bore and surrounding linkages, though careful application is required to avoid sensitive sensors and electrical components.

• Designed for cleaning without dismantling carburettors and throttle bodies.
• Aerosol delivery reaches hard-to-access spots when aimed correctly.
• Follow vehicle manufacturer guidance for safe on-engine cleaning.

Is it suitable for all engine types and systems?

This throttle valve cleaner is formulated specifically for use in gasoline engines and fuel systems. It is not recommended for diesel engines or components incompatible with its solvent base; always check compatibility with seals, plastics and sensors on modern vehicles.

• Made for gasoline carburettors and fuel-injection throttle bodies.
• Not designed for diesel applications or non-gasoline components.
• Test on small area if unsure about plastics or painted surfaces.

What are the practical application tips for safe, effective use?

Use in a well-ventilated area, protect nearby electrical connectors, and allow the solvent to evaporate before restarting the engine. Wear gloves and eye protection, and follow local disposal rules for aerosol cans.

• Shake can well and direct spray at the deposit area from a short distance.
• Avoid spraying directly onto wiring, sensors or painted surfaces.
• Allow parts to dry fully before engine start; repeat if heavy deposits remain.

Who is this for: Professionals and experienced DIY mechanics who work on gasoline-powered vehicles and need a reliable, workshop-strength throttle and carburettor cleaner that reduces service time by allowing in-place cleaning. It suits tune-up technicians, restoration projects, motorcycle and small-engine repairs where safe solvent use is understood and appropriate precautions are taken.
