Three-Way Catalytic Converter Cleaning Agent 120ml for Exhaust System Maintenance

This catalytic converter cleaning agent is formulated to help remove carbon deposits that accumulate inside three-way converters over time. A restricted converter can lead to reduced engine power, higher fuel consumption, and increased emissions. By adding this 120ml treatment to your fuel tank, you introduce a blend of active solvents and combustion enhancers that work as the engine runs. The formula includes polyether amine, dodecane, fatty acid ester, mineral oil, phosphate ester, and ferrocene to break down and flush out deposits without requiring dismantling. This product is designed as a simple fuel additive, making it accessible for routine maintenance.

Features and Construction

Every aspect of this cleaning agent is built around targeted chemical action. The ingredient list combines solvent carriers with a metal-organic compound to promote deposit removal during normal engine operation.

Ingredient Blend

The cleaning agent contains six stated components: polyether amine, dodecane, fatty acid ester, mineral oil, phosphate ester, and ferrocene. Each plays a role in dissolving carbon-based deposits or assisting the combustion process inside the catalytic converter. This multi-component approach addresses different types of build-up.

Single-Dose Volume

Each bottle holds 120ml of liquid, intended as a one-off treatment for a standard vehicle fuel tank. The measured dose means you do not need to guess quantities or measure increments. Simply pour the full bottle into the tank before filling with fuel.

Uses and Placement

This product is designed for vehicles equipped with a three-way catalytic converter. It is added directly to the fuel system, so no mechanical access to the exhaust is needed.

Fuel Additive Application

Pour the entire 120ml into the fuel tank before adding fuel. The cleaning agent mixes with petrol or diesel and passes through the engine and exhaust system, where its active ingredients interact with converter deposits. Use with a full tank to ensure even distribution.

Routine Maintenance Treatment

This cleaning agent can be used as part of periodic exhaust system maintenance. Applying it at regular intervals may help prevent severe blockages from forming. The exact frequency depends on driving conditions and fuel quality, but a single bottle is enough for one treatment cycle.

Benefits and Buying Value

Choosing a dedicated catalytic converter cleaner offers targeted action compared to general fuel system additives. The ingredient list is specifically selected to address three-way converter deposits.

Restored Exhaust Efficiency

By reducing carbon build-up, the cleaning agent helps the converter operate closer to its original specification. This can improve exhaust gas flow and maintain proper engine back-pressure, which supports fuel economy and emissions control.

Simple DIY Maintenance

No special tools or professional help are required. The bottle is designed for straightforward pouring into the fuel filler neck. This makes it a practical option for car owners who want to perform basic exhaust system care themselves.
