Catalytic Converter Cleaner

5 Things You Should Know About Catalytic Converter Cleaners

Before discussing catalytic converter cleaners, it’s important to understand the structure and function of the catalytic converter itself. This essential component helps the vehicle’s exhaust system operate efficiently by reducing harmful emissions.

A catalytic converter is installed in the exhaust system to reduce harmful pollutants released into the atmosphere. It is a key part of modern emissions control systems.

When a catalytic converter becomes clogged or restricted, several symptoms may appear, indicating a problem with the exhaust system. In many cases, using a catalytic converter cleaner can help resolve these issues.

A catalytic converter cleaner is designed to clean the converter from the inside. Regular catalytic cleaning during routine maintenance improves emissions efficiency and reduces harmful pollutants. Ignoring the problem can make it worse — timely cleaning prevents costly repairs.

The cleaning process involves using a chemical solution that breaks down and removes contaminants inside the converter. Over time, pollutants accumulate and cause clogging, reducing performance and increasing emissions.

Note: In some cases, a welded catalytic converter may require replacement rather than cleaning. However, many converters can be restored through proper cleaning.

Catalytic converter cleaner is typically added directly to the fuel tank, where it mixes with the fuel and passes through the engine and exhaust system. Always choose a high‑quality cleaner from a reputable manufacturer. Saving on quality often leads to bigger problems later.

1. How Catalytic Cleaning Works

To use catalytic converter cleaning products, always follow the instructions on the packaging, as procedures may vary by manufacturer.

  1. Add the cleaning solution directly to the fuel tank. Determine the tank volume and follow the dosage instructions.
  2. Drive the vehicle for at least 20–30 minutes to allow the cleaner to circulate through the engine and exhaust system. This helps break down and remove contaminants from the converter surface.

Cleaning products cannot guarantee full restoration of a severely clogged or damaged catalytic converter. In some cases, professional repair or replacement may be required. Always use a cleaner designed specifically for your vehicle and follow recommended dosage and frequency.

2. Catalytic Treatment Additives

A catalytic and exhaust treatment additive is a chemical product used to enhance the performance and efficiency of the exhaust system. These additives clean and maintain the catalytic converter using detergents, solvents, and corrosion inhibitors that are safe for both the vehicle and the environment.

Using a catalytic converter cleaning treatment helps restore performance by removing carbon deposits, soot, and other contaminants. These additives may also contain lubricants to prevent new deposits from forming.

3. Catalytic Converter Oxidation Explained

Catalytic converters use a process called catalytic oxidation of volatile organic compounds (VOCs) to reduce harmful emissions. The converter reduces carbon monoxide, nitrogen oxides, and other pollutants released into the environment.

  • Exhaust gases pass through the converter and contact a catalyst made of platinum, palladium, and rhodium.
  • The catalyst breaks down harmful pollutants into carbon dioxide, water vapour, and nitrogen.
  • This process is essential for reducing air pollution and improving air quality.

Regular maintenance and cleaning ensure the catalytic converter continues to operate efficiently and reduce harmful emissions.
