How to Clean a Catalytic Converter


A catalytic converter is a device that reduces carbon monoxide and nitrogen oxide emissions from your car’s exhaust. These two gases are toxic and can cause smog and acid rain, so they must be reduced.

However, these devices can get clogged up over time. This can lead to problems with your vehicle’s performance and gas mileage.

1. Remove the Muffler

A catalytic converter is a crucial part of a car’s exhaust system that reduces harmful emissions. It contains precious metals that react with nitrogen oxides and hydrocarbons in the exhaust to form harmless water and carbon dioxide.

Some cars’ catalytic converters can become clogged with deposits over time. It may be possible to unclog the converter by using a chemical cleaner.

However, if the converter is badly clogged, it’s best to get it replaced.

A clogged catalytic converter can cause poor fuel economy, engine rattling, and a check engine light. It can also be a source of low-end torque loss, and driving without these pollution-controlling components in some states is illegal.

2. Remove the Exhaust Pipe

The catalytic converter is an exhaust system component that helps the car’s engine run more efficiently by converting poisonous emissions into less toxic gases. This can reduce the amount of harmful gas released into the atmosphere and also decreases fuel consumption.

A catalytic converter comprises metals such as palladium, rhodium, and platinum. When the waste gases travel through these metals, a chemical reaction removes up to 90 percent of the toxins.

Some thieves can cut out and remove catalytic converters from the exhaust pipes, so it is essential to have the system checked periodically. If a catalytic converter is tampered with, it could cause your vehicle to fail an emissions test or be fined.

3. Remove the Catalytic Converter

A catalytic converter is a crucial part of your vehicle’s exhaust system that helps convert harmful gases and pollutants into less dangerous compounds. When your catalytic converter becomes rusted or broken, it can cause your car to emit toxic fumes into the air.

The best way to clean your catalytic converter is by obliterating it from your exhaust system. This can significantly improve your car’s performance by letting the engine breathe more freely and improving its sound and gas mileage.

Removing a catalytic converter is legal, but it’s a good idea to check with your local authorities first. It’s also important to note that catalytic converter theft is becoming a common problem, and if you live in a city or state where it’s a concern, it’s best to be safe than sorry.

4. Pour the Catalytic Converter Cleaner into the Fuel Tank

A catalytic converter is a vital part of an exhaust system that gulps in harmful gases and turns them into less harmful ones. They also help your car pass emissions tests and keep the air clean for everyone to breathe.

Your car’s catalytic converter needs regular cleaning to keep it functioning correctly. If it’s clogged, it can affect how much gas your engine can burn, which can shorten its life and make it more expensive to repair.

You can get a bottle of catalytic converter cleaner and pour it into your fuel tank just like you would when filling up. You’ll want to do this at least once a year or as recommended on the bottle.

Once you’ve poured the cleaner into your fuel tank, drive your car for 30 minutes to let it work its magic in your vehicle’s exhaust system. This will ensure the cleaner has time to work into your catalytic converter.

5. Drive the Car

A catalytic converter is a component of your car’s exhaust system that reduces air pollution by converting pollutants into non-polluting substances. It works on both gasoline and diesel engines.

The first step to cleaning your catalytic converter is to remove it from the car’s exhaust pipe and inspect it for damage or rattling noises. This could indicate loose parts clogging the exhaust pipe and blocking gas from coming out.

You can also use a pressure washer and a cleaning solution to clean the inside of the converter. This is one of the easiest ways to clear out deposits and return your emissions to normal levels.
