Holts | Professional EGR & Carb Cleaner - 500ml

Holts Professional EGR & Carb Cleaner is an advanced, trade-grade chemical aerosol treatment engineered to aggressively penetrate, dissolve, and flush heavy carbonized crusts and oily resins. The product comes packaged in a premium 500ml pressurized slim canister sporting a sleek white, black, and red livery accented by the iconic Union Jack flag, highlighting its high-velocity execution as a comprehensive induction and emission valve purger Its premium British-engineered formulation offers a 360-degree spray design that delivers reliable performance across restricted mechanical pathways, providing absolute throttle and exhaust gas recirculation defense.

Specifications:

• Brand: Holts.

• Product Line: Professional Workshop Additives & Cleaners.

• Product Type: Heavy-Duty EGR & Carburettor Aerosol Purger.

• Net Capacity: 500 ml.

• Country of Origin: United Kingdom.

• Delivery Mechanics: Engineered with 360° all-angle valve technology.

Benefits:

• High-Efficiency EGR Decontamination: Specifically targeted to break down crusty carbon soot, tar, and ash compounding inside Exhaust Gas Recirculation (EGR) valves, preventing valve sticking.

• Carburettor Port Stripping: Penetrates deeply to liquefy baked-on gasoline varnish, heavy fuel lacquers, and sticky gums blocking delicate internal jets and venturis.

• Air Intake Throttle Restructuring: Clears oil mist accumulation and dark road films off throttle body butterflies and housing throats, securing uninhibited induction volumetric efficiency.

• Idle Stabilization and Correction: Drastically remedies rough idle vibrations, erratic RPM drops, and low-speed engine hesitation rooted in a choked air intake track.

• Exhaust Smoke Mitigation: Restores targeted factory-spec air-to-fuel balance, optimizing thermal efficiency to significantly lower black tailpipe emissions and smoke output.

• 360° Multi-Directional Application: Built with a highly versatile propellant system that allows the user to spray effectively at any angle, even completely upside down, to access buried linkages.

How to Use:

1. Ensure the vehicle’s engine is entirely switched off and all localized exhaust and intake manifolds have cooled down before spraying.

2. Shake the 500ml Holts canister vigorously to ensure full suspension of the concentrated active stripping agents.

3. Disconnect the air intake ducting to fully expose the throttle body housing or remove the targeted EGR valve from its manifold seat.

4. Spray the chemical solvent directly onto the encrusted carbon components using steady strokes, allowing the fluid to actively dissolve and wash the sludge downward.

5. For heavy, thick carbon shells, allow the fluid to sit and soak for a few minutes, use a soft detailing brush to agitate, and rinse thoroughly with a final heavy spray.

6. Re-install all mechanical components and vacuum lines securely, start the vehicle, and allow it to idle for a few minutes to clear any residual chemical fumes safely.

Suitable For:

• Mechanical carburettors, automotive EGR valves (both petrol and diesel passenger vehicles), electronic throttle bodies, idle air control valves, and unpainted workshop components facing heavy carbon choking.

Note:

• This high-grade fluid is a highly potent corrective and preventive workshop servicing stabilizer; to secure clean, uninhibited combustion and stop performance-robbing buildup within your emission structure, it is highly recommended to integrate this premium British aerosol into your regular tuning schedule.
