Locate the entry point of the intake manifold and remove any components obstructing access to it. Spray Intake Valve Cleaner: With access to the intake manifold, use the intake valve cleaner spray to apply a generous amount to the intake. This cleaner is formulated to dissolve carbon deposits on the valves.
Turn the crankshaft to open each valve, and carefully remove any visible carbon deposits on the valves and valve seats, using only a brass wire brush. CAUTION: Do not allow grit to fall into the valve chambers or between the piston and the cylinder wall.
Issues with intake valves can lead to poor combustion, compromising the proper operation of the vehicle over time and reducing its performance. The indicators of valve issues include noise (ticking), loss of power, any ignition difficulties, high fuel consumption, and excessive smoke from the exhaust.
Acetone and/or carb cleaner will work.
Intake valve build-up can slow down air flow, resulting in performance and driveability issues like hesitation, stumbling, and hard starting. We recommend cleaning your intake valve at regular 15,000-30,000 mile intervals or as required.
Use Sea Foam® Spray to clean carbon deposits from the intake systems, intake valves, and combustion chambers of your engine. Use Sea Foam® Spray to clean all of these areas with the cleaning tube inserted into the sealed air intake system. Spray Sea Foam® Spray into the engine from the front of the throttle plate.
Oil Vapor and Blow-by:
To maintain proper pressure, the crankcase vapors laden with oil particles are recirculated back into the intake manifold through the Positive Crankcase Ventilation (PCV) system. In direct injection engines, these oil vapors can settle on the intake valves and solidify, leading to carbon buildup.
Bore Tech's C4 Carbon Remover™ is a cutting-edge carbon cleaner that quickly and effectively removes heavy carbon fouling without the hazards, toxicity, and odors typically found in competitive cleaners.
Sea Foam Spray delivers a high cleaning concentration to carburetor throttle valves, intake runners and valves, and chamber areas.
Gumout® All-In-One® Complete Fuel System Cleaner uses P.E.A. (polyetheramine) to effectively remove carbon deposits other products can't for improved performance across the fuel system.
When your car is idling or stationary, you should feel and hear the smooth vibrations of an efficient engine. If you notice unusual noises, in particular a coughing, popping or spitting noise, it suggests that the engine isn't getting enough airflow, which means your air filter needs to be replaced.
In a nutshell, these tools can boost your car engine's efficiency, prevent rust buildup, improve fuel economy, and lower emissions. Therefore, consider using high-quality valve cleaners to extend the engine's lifespan.

Spray Intake Valve Cleaner: With access to the intake manifold, use the intake valve cleaner spray to apply a generous amount to the intake. This cleaner is formulated to dissolve carbon deposits on the valves.
Manual Cleaning: Disassemble the cylinder head and use brass wire brushes, scrapers, and solvents to clean valves thoroughly. This approach is labor-intensive but effective. Media Blasting: Walnut shell blasting is a specialized technique that removes carbon without damaging the valves.
While WD-40® does not technically “clean”, it does an amazing job of removing oils and carbon. This is a must when removing build up in an engine. WD-40® also helps displace water to prevent rust.
Use Carburetor Cleaner
Use a rag or soft-bristled brush to clean the valve components. Spray another coat of cleaner on them if needed and let them sit.
