Can You Clean A Catalytic Converter With Carb Cleaner?

Last Updated on October 6, 2023 by Matthew Lloyd

Yes, it is possible to clean a catalytic converter with a carb cleaner, but it requires caution and adherence to proper cleaning techniques. Carb cleaner can help remove carbon deposits and improve the efficiency of the catalytic converter. However, it’s important to note that carb cleaners are highly flammable and should only be used in a well-ventilated area. Pouring carb cleaners directly onto the engine can cause explosive reactions. It’s recommended to follow specific instructions and consider alternative cleaning methods to clean catalytic converters, like using fuel additives, carpet cleaner, lacquer thinner, or hydrogen peroxide. Cleaning of the catalytic converter can lead to improved engine performance, reduced emissions, and a prolonged lifespan for the catalytic converter.

Considerations while Cleaning a Catalytic Converter with Carb Cleaner

Carb cleaner can be used to clean a catalytic converter, but there are important factors to consider before attempting this method. Here are some points to keep in mind:

1. Carb cleaner is highly flammable and should only be used in a well-ventilated area to avoid potential safety hazards. Safety should always be a top priority when working with any cleaning agents.
2. The catalytic converter is a delicate component, and improper cleaning techniques can cause damage or contamination. It’s crucial to exercise caution and follow the correct procedure to avoid any adverse effects.
3. Pouring carb cleaners directly onto the engine can lead to an explosive reaction. It’s essential to avoid contact between carb cleaners and other engine parts.
4. While carb cleaner can remove carbon buildup on the catalytic converter, it may not address other underlying issues that can affect its performance. Therefore, diagnosing the root cause of any catalytic converter problems is crucial before attempting a cleaning method.

Alternative Methods to Clean a Catalytic Converter: Step-by-Step Guide

Cleaning a catalytic converter requires careful attention and adherence to specific steps. Here is a step-by-step guide to cleaning your clogged catalytic converter using various methods:

Method 1: Using Cataclean Fuel Additive

1. Purchase a reputable catalytic converter cleaner like Cataclean, designed specifically for this purpose.
2. Ensure your vehicle’s gas tank is at least a quarter empty, as this will allow for the proper concentration of the cleaning agent.
3. Pour the recommended amount of Cataclean fuel additive into your gas tank.
4. Drive your vehicle for 10 to 15 miles under normal driving conditions, allowing the cleaning agent to circulate through the fuel system and catalytic converter.
5. Refuel your gas tank to its normal capacity.
6. Monitor your vehicle for any improvements in performance and the check engine light. Regular use of catalytic converter cleaners may be necessary to maintain its efficiency.

Method 2: Using Carpet Cleaner

1. Prepare an endoscope camera to inspect the condition of the catalytic converter before cleaning.
2. Remove the oxygen sensor using a 22mm wrench or the appropriate tool.
3. Apply WD-40 to the oxygen sensor and let it penetrate for a few minutes.
4. Connect the endoscope camera to visually assess the catalytic converter’s condition. Look for signs of clogging or carbon buildup.
5. Mix carpet cleaner with water in a canister, ensuring the appropriate concentration.
6. Attach a sharp air nozzle to regulate the pressure to approximately 60 psi.
7. Insert the nozzle into the oxygen sensor hole and open the lower valve, spraying the carpet cleaner onto the catalytic converter. Ensure thorough coverage.
8. Allow the cleaner to sit for a few minutes to dissolve any carbon deposits.
9. Close the lower valve and remove the nozzle.
10. Reinstall the oxygen sensor and start the engine, allowing it to push out any loosened debris through the exhaust.
11. Let the engine run for a few minutes, then cool down before removing the oxygen sensor to inspect the cleaned catalytic converter.

Method 3: Using Lacquer Thinner

1. Add a gallon of lacquer thinner to your gas tank when it is half full.
2. Drive your vehicle for approximately 150 miles at higher speeds, preferably maintaining 2,500 RPM for about 30 minutes.
3. The lacquer thinner will help burn impurities and clean the catalytic converter.
4. If the cleaning process doesn’t resolve the issue, removing the catalytic converter and cleaning it separately may be necessary.
5. To remove internal deposits, Prepare a bucket with laundry detergent soap and soak the catalytic converter overnight.
6. Rinse the catalytic converter thoroughly and reinstall it in your vehicle.

Method 4: Using Hydrogen Peroxide

1. Warm up your vehicle’s catalytic converter by driving it to operating temperature.
2. Mix sodium hydroxide (lye) with water, creating a strong solution.
3. Apply the sodium hydroxide solution to the catalytic converter, allowing it to soak for approximately 20 minutes.
4. Thoroughly rinse the catalytic converter, ensuring no residue remains.
5. Reinstall the catalytic converter and perform temperature tests to assess its efficiency.

Benefits of Cleaning a Catalytic Converter

Cleaning your catalytic converter can offer several advantages:

1. Improved engine performance: A clean catalytic converter allows for efficient exhaust gas processing, enhancing engine performance and fuel efficiency.
2. Reduced emissions: A clean catalytic converter helps lower harmful emissions by removing carbon deposits and contaminants, creating a cleaner environment.
3. Cost-effective solution: Cleaning your catalytic converter is more affordable than replacing it entirely, especially if the issue is minor.
4. Prolonged lifespan: Regular cleaning can help extend the lifespan of your catalytic converter, avoiding premature failure and expensive replacements.
