Catalytic Converter Cleaner 100ml – Liquid Exhaust Deposit Removal Solution for Petrol and Diesel Engines

100ml catalytic converter cleaner liquid in a white bottle with orange label, suitable for petrol and diesel cars

Catalytic converters are essential for reducing exhaust emissions, but carbon and sulphur deposits can gradually reduce their efficiency, leading to poor engine performance, higher fuel consumption, and potential MOT test failures. This 100ml catalytic converter cleaner offers a straightforward solution: a liquid formula that you add directly to the fuel tank. The active ingredients work through the combustion process to break down and remove stubborn deposits from the converter, oxygen sensors, and exhaust system. Compatible with both petrol and diesel engines, this treatment helps restore exhaust flow, improve combustion, and cut harmful emissions without mechanical intervention.

How the Cleaner Works in Your Fuel System

The liquid formulation is designed to mix with fuel and travel through the engine into the exhaust system. As it passes over the catalytic converter and sensors, the chemical agents target carbon build-up and other contaminants, gradually dissolving them so they can be expelled during normal driving.

Surfactant-Based Cleaning Action

The formula includes sodium lauryl polyether sulfate and two fatty alcohol polyethers (3 and 9) that act as detergents to lift and disperse carbon deposits from metal surfaces inside the converter. These surfactants reduce surface tension, allowing the solution to penetrate baked-on residues more effectively.

Solvent and Chelating Agents

Dipropylene glycol methyl ether serves as a powerful solvent to break down organic deposits, while sodium gluconate and citric acid work as chelating agents to bind with mineral contaminants and prevent re-deposition. Disodium EDTA further enhances the removal of metal ion deposits that can block catalyst pores.

Fuel Tank Delivery System

The entire 100ml dose is added to a near-empty fuel tank before refuelling. This ensures proper mixing with the fuel and consistent delivery to the engine. After treatment, a drive of at least 30 minutes allows the solution to circulate fully through the exhaust system.

Compatibility and Usage Recommendations

This catalytic converter cleaner is designed for use in standard petrol and diesel vehicles. It works with both naturally aspirated and turbocharged engines. The 100ml bottle provides a single treatment dose, making application simple for any vehicle owner.

Petrol and Diesel Engine Suitability

Whether you drive a petrol or diesel car, this cleaner can be used without modification. It addresses the common problem of carbon build-up in direct-injection petrol engines and diesel particulate filter (DPF) systems alike, helping to maintain exhaust efficiency across a wide range of vehicles.

Regular Maintenance Integration

For best results, use every 3,000 to 5,000 miles or whenever you notice reduced fuel economy, rough idling, or a drop in engine responsiveness. Regular application can help prevent severe clogging that would otherwise require expensive professional cleaning or converter replacement.

Simple No-Tool Application

No special tools, mechanical knowledge, or garage visits are required. Simply open the bottle, pour the liquid into the fuel tank before filling up, and drive normally. This makes it a practical choice for everyday motorists who want to maintain their exhaust system without hassle.

Benefits and Value of Regular Use

Using a catalytic converter cleaner as part of your vehicle maintenance routine can deliver several practical benefits. It helps sustain fuel economy, reduces the risk of MOT test failures related to emissions, and extends the effective life of the converter by keeping it free from deposits.

Improved Fuel Economy and Performance

When the catalytic converter is clogged, the engine works harder to expel exhaust gases, which increases fuel consumption. By removing carbon deposits, this cleaner helps restore normal backpressure and airflow, allowing the engine to run more efficiently and potentially improving miles per gallon.

Emissions Reduction and MOT Readiness

High emissions are a common reason for MOT failures. A clean catalytic converter is more effective at converting harmful gases like carbon monoxide, hydrocarbons, and nitrogen oxides into less toxic substances. Regular use of this cleaner can help maintain emissions within legal limits.

Cost-Effective Maintenance Alternative

Replacing a clogged catalytic converter can cost hundreds of pounds. This 100ml treatment offers a low-cost preventative measure. Applied at regular intervals, it may delay or avoid the need for converter replacement, saving both money and the inconvenience of a major repair.
