Catalytic Converter Cleaner with polyether amine and ferrocene formula, 120ml bottle designed for petrol and diesel engines to reduce harmful emissions and restore performance by cleaning catalytic converters and oxygen sensors
Catalytic Converter Cleaner: 120ml Bottle with Polyether Amine and Ferrocene Formula for Petrol and Diesel Engines

This catalytic converter cleaner is a 120ml liquid additive formulated with a specific blend of six ingredients: polyether amine, dodecane, fatty acid ester, mineral oil, phosphate ester, and ferrocene. It is designed to be added to the fuel tank of both petrol and diesel vehicles. The product aims to clean and maintain the catalytic converter and oxygen sensors, key components in a vehicle's exhaust emission control system. Over time, these parts can become clogged with carbon and other deposits, leading to reduced engine performance, lower fuel economy, and increased harmful emissions. This cleaner provides a maintenance solution intended to help restore proper function by dissolving these deposits as the treated fuel passes through the exhaust system.
Features and Construction
The product is constructed as a ready-to-use liquid formulation supplied in a single 120ml bottle. Its value lies in the practical combination of its stated ingredients, each serving a potential role in fuel system and emission system maintenance without the need for mechanical disassembly.
Material and Build
The cleaner's formulation is based on a blend of chemicals commonly found in automotive additives. Polyether amine is widely recognised for its deposit-cleaning properties in fuel injectors and intake valves. Dodecane acts as a hydrocarbon solvent. Fatty acid ester and mineral oil typically function as carriers and lubricants. Phosphate ester can contribute stabilising properties. The inclusion of ferrocene is notable, as this organometallic compound can act as a combustion catalyst, potentially helping to reduce soot formation and lower tailpipe emissions during the cleaning process.
Size and Practical Fit
The product is offered in a single 120ml bottle, which is a standard treatment size for one tank of fuel for most cars and vans. This size is convenient for a single application, fitting easily into a vehicle's boot or garage shelf. The packaging is designed for direct use; the entire bottle is typically poured into the fuel tank. It is formulated to be compatible with both unleaded petrol and standard diesel, covering a broad range of modern vehicles without requiring a specific variant.
Uses and Placement
This cleaner is positioned as a maintenance product for vehicle owners noticing symptoms of emission system issues or seeking preventative care. It is not a mechanical repair tool for failed components but aims to address performance degradation caused by buildup.
Event or Professional Use
For professional or enthusiast use, the product can be incorporated into a regular vehicle servicing schedule. Mechanics or detailers might use it as part of a decarbonisation service to help clean the exhaust system without physical removal. It is also suitable for vehicles undergoing an emissions test preparation, where a cleaner system may help achieve a pass result. The formula's compatibility with both fuel types makes it a versatile stock item for workshops dealing with varied vehicle fleets.
Everyday Home Use
For the everyday driver, this cleaner offers a straightforward DIY solution. Common indicators for its use include a noticeable drop in fuel economy, a sluggish engine response, or the illumination of an engine warning light related to emissions (such as a P0420 catalyst efficiency code). Using the cleaner as directed can be a first step before investigating more costly repairs. It is a simple add-to-fuel process that requires no special tools or technical knowledge, making it accessible for most vehicle owners.
Benefits and Buying Value
The primary value proposition is the potential to improve vehicle performance and emissions through chemical cleaning, which may delay or avoid the high cost of catalytic converter replacement.
Reuse and Low Maintenance
The product is a consumable used on an as-needed basis rather than a permanent install. A single 120ml bottle treats one tank of fuel. For ongoing maintenance, it could be used periodically, such as during every major service or every few thousand miles, depending on driving conditions. The low-maintenance aspect is its simplicity; it integrates into the normal refuelling routine without requiring garage time or labour costs. The formulation is designed to work with standard fuels and does not typically require follow-up treatments or flushes.
Why Choose This Product
This catalytic converter cleaner may be chosen over a generic fuel additive due to its specific ingredient blend targeting exhaust system deposits, including ferrocene for emission reduction. Its clear formulation for both petrol and diesel engines removes the need to select a specific fuel-type product. The 120ml single-bottle format provides a complete dose without measurement, reducing the chance of incorrect application. For buyers seeking a practical, non-mechanical approach to addressing early signs of catalytic converter clogging or aiming to maintain emission system health, this product offers a defined chemical solution based on commonly used additive components.
