Three-Way Catalytic Converter Deep Cleaning & Restoration Kit – Water-Based Formula

The Three-Way Catalytic Converter (TWC) Deep Cleaning Kit is a professional-grade, water-based maintenance solution designed to restore the efficiency of your vehicle’s exhaust after-treatment system. Over time, catalytic converters can become clogged with sulfur, phosphorus, and carbon deposits, leading to reduced engine performance and increased emissions. This advanced kit utilizes a specialized chemical formula to dissolve these stubborn contaminants and unclog the converter honeycomb structure. More than just a cleaner, it acts as a restorer by reactivating the precious metals—such as platinum and rhodium—embedded within the catalyst, ensuring optimal conversion of harmful gases like CO, HC, and NOx. Safe for oxygen sensors and compatible with modern emission systems, this kit is essential for passing emissions tests and extending the lifespan of your catalytic converter.

Application Scenarios

• Emissions Test Failure: Ideal for vehicles that have failed smog checks due to high levels of CO, HC, or NOx emissions caused by a sluggish catalyst.
• Routine Exhaust Maintenance: Recommended as part of regular vehicle servicing (e.g., every 20,000 – 30,000 km) to prevent carbon buildup and maintain peak exhaust flow.
• Performance Restoration: Suitable for older vehicles experiencing power loss or poor fuel economy attributed to a restricted exhaust system.
• Preventative Care: Can be used proactively on high-mileage vehicles to delay the expensive replacement of the catalytic converter.

Product Functions 

• Deep Cleaning: Effectively removes sulfur, phosphorus, and chemical deposits that accumulate on the catalyst surface.
• Catalyst Reactivation: Helps wake up dormant platinum and rhodium active sites, restoring the chemical conversion efficiency of the TWC.
• Emission Reduction: Significantly lowers the output of harmful pollutants (Carbon Monoxide, Hydrocarbons, Nitrogen Oxides), helping vehicles meet environmental standards.
• Performance Boost: By unclogging the exhaust path, it reduces backpressure, which can lead to improved engine responsiveness and fuel efficiency.
• Component Protection: The water-based formula is non-corrosive and safe for use with oxygen sensors and other sensitive exhaust components.

Product Features

• Advanced Water-Based Formula: Unlike harsh solvent-based cleaners, this water-based solution is safer for the environment and internal engine components while remaining highly effective.
• Dual-Action Technology: Combines powerful cleaning agents with restoration additives to both clean existing dirt and protect against future buildup.
• Easy Application: Designed for convenient use during standard maintenance intervals without requiring complex disassembly of the exhaust system.
• Cost-Effective Solution: Extends the service life of the expensive catalytic converter, saving vehicle owners significant repair costs.
• Universal Compatibility: Formulated to be safe for most gasoline engines equipped with three-way catalytic converters.
