How to Clean a Catalytic Converter

Summary

In this video, the creator demonstrates how to clean a catalytic converter using vinegar and distilled water. Despite common belief that catalytic converters can't be cleaned, the process involves soaking the parts in vinegar to remove carbon and particulates. The creator explains the importance of using distilled water to avoid mineral contamination and shares tips on handling clogged converters. While this method offers a short-term fix, it’s not a permanent solution. The video highlights the importance of proper maintenance, and the creator offers insight into cost-saving measures for those dealing with a clogged catalytic converter.

Takeaways

• 😀 Conventional wisdom says catalytic converters can't be cleaned, but with the right method, you can extend their life temporarily.
• 😀 Cleaning a catalytic converter can save money if you're on a budget, but it won't fix long-term issues.
• 😀 Catalytic converters need to be soaked in distilled white vinegar to clean out carbon and other particulates.
• 😀 The converters should be placed upright in a bucket to allow gravity to help clean them more effectively.
• 😀 Distilled white vinegar is crucial for cleaning—do not use apple cider vinegar or other types.
• 😀 Using distilled water to rinse the converters is essential, especially if you live in an area with hard tap water, to avoid mineral buildup.
• 😀 Allow the converters to soak for at least one to two hours to remove as much debris as possible.
• 😀 Rinsing should be done carefully to ensure all carbon and contaminants are removed from the inside of the converter.
• 😀 Catalytic converters should be checked for cracks before cleaning; if cracked, replacement is necessary.
• 😀 After cleaning, install the catalytic converters as soon as possible to prevent rust from forming.
• 😀 Cleaning a catalytic converter can provide a temporary fix for performance issues caused by clogging, but eventually, a replacement may be necessary.

Q & A

What is the main purpose of cleaning a catalytic converter in the video?

The main purpose is to temporarily clean a catalytic converter to improve performance, especially if it's clogged due to oil burning in the engine. It's a cost-saving measure but not a permanent solution.

Why does the narrator mention that conventional wisdom says you can't clean a catalytic converter?

Conventional wisdom suggests that catalytic converters can't be cleaned because they are often thought to be a one-time use part that should be replaced once clogged. However, the narrator demonstrates that cleaning can work as a temporary fix if done properly.

What is the recommended method for cleaning a catalytic converter in the video?

The catalytic converter is soaked in distilled white vinegar to loosen carbon buildup and other particulates. Gravity plays a role in the cleaning process, with the inlet side facing down to allow particles to fall out naturally.

Why is it important to use distilled white vinegar for cleaning the catalytic converter?

Distilled white vinegar is recommended because it's clean and free of impurities that could cause further contamination. Apple cider vinegar or other types could introduce unwanted substances, affecting the cleaning process.

What role does gravity play in the cleaning process of the catalytic converter?

Gravity helps in dislodging particles from the catalytic converter. By positioning the inlet side down, the contaminants and carbon particles are allowed to fall out, aided by gravity.

What is the significance of using distilled water for rinsing the catalytic converter after cleaning?

Distilled water is necessary because tap water, especially in areas with hard water, contains minerals that could reattach to the metal inside the catalytic converter, counteracting the cleaning efforts.

What potential issue is associated with cleaning a cracked or damaged catalytic converter?

If a catalytic converter is cracked or severely damaged, cleaning it will not be effective, and it should be replaced instead. A cracked cat can lead to further issues, including exhaust leaks and reduced performance.

How long does the cleaning process take, according to the video?

The cleaning process takes several hours, as the catalytic converter is left soaking in vinegar for a couple of hours to allow the contaminants to loosen up before being rinsed out.

What does the narrator suggest you do after cleaning the catalytic converter to prevent rust?

After cleaning the catalytic converter, it's important to reinstall it and run the vehicle soon to ensure all the water evaporates, preventing rust from forming inside the converter.

What are the limitations of this cleaning method for catalytic converters?

This cleaning method is only a temporary solution. It can help get a vehicle running again for a short period but is not a long-term fix. A full replacement is often necessary for proper, long-lasting performance.
