It can get rid of all the dirt clogging the converter quickly.Even if you do not have a current problem in your vehicle’s catalytic converter, it is recommended that you use a cleaner at least four times a year.
Auto Repairs Are EXPENSIVE
In this article, we will start with background information about the catalytic converter, the main reasons causing a catalytic converter to clog, and the ten best catalytic converter cleaners for the year 2020.
What Does the Catalytic Converter Do?
Combustion engines provide the appropriate power to the vehicle to move. However, these engines also produce harmful emissions.
Think of the catalytic converter as an emission filter. Although the converter does not filter anything, it CONVERTS the vehicle’s harmful emissions into less harmful gasses.
When the emissions pass through the catalytic converter, a chemical reaction occurs between the emissions and the metal parts of the converter. As a result of the chemical reaction, the harmful emissions are converted to specific, less dangerous products.
Catalytic converter’s problems occur when the vehicle is running “rich.” In other words, if the air-fuel mixture has more fuel than the required, there will be unburnt fuel in the cylinders. The unburnt fuel can build up carbon in the catalytic converter causing it to clog.
What Causes is Catalytic Converter Clogging?
The most common cause for catalytic converter clogging is when the car runs rich or when the air-fuel mixture has more fuel than the optimal. The unburnt fuel can cause carbon to buildup in the catalytic converter, and therefore, the converter will clog.
One of the first reasons for a rich air-fuel mixture is problems with the spark plugs.
You need to know how often you should replace the spark plugs by reviewing the vehicle’s owner’s manual. If you do not have a copy of your vehicle’s manual, you can search for it and find it online.
The vehicle’s owner’s manual can tell you exactly when to replace the spark plugs, how many spark plugs do you need for your car, how much should each spark plug cost you, and how much of labor effort cost to expect.
Therefore, if you do not remember when you changed your spark plugs, it might be time to change them.
The vehicle’s come with four, six, or eight cylinders; therefore, you need to know how many to buy and if you can see by each separately.
Once you have changed your spark plug, it is now the time to use a catalytic converter cleaner.
Will the Catalytic Converter Cleaner Solve the Problem?
A lot of people ask the same question and wonder if the catalytic converter cleaner will solve the problem forever.
The answer to this question depends. If the catalytic converter has a relatively small amount of clogging, you can simply use one bottle of catalytic converter cleaner and solve the issue.
However, if the dirt and clogging is a decade worth of carbon buildup, you might need to use more than one bottle of catalytic converter cleaner to get rid of the problem entirely.
Lastly, if the catalytic converter has severe problems, unfortunately, you might not have any other option than replacing the whole part.
In general, it is recommended to clean your catalytic converter four times every year.
The cleaner is a cheap solution when it is compared to the cost of replacing the catalytic converter.
Can I Drive My Car If the Catalytic Converter is Clogged?
A Clogged catalytic converter will not stop the car from moving unless the clogging is severed.
If the catalytic converter is lightly clogged, you can drive your vehicle just fine.
However, you need to note that the vehicle will not perform as it should be. In other words, you will have significantly less fuel efficiency, and you will pay more for gas.
Besides, the vehicle will emit thick smoke that might be offensive to some people.
On the other hand, if the catalytic converter is completely clogged, you will not be able to drive the vehicle at all. In this scenario, it is most likely that the cleaner will not be able to fix the problem, and you will need to replace the whole part.
How Long Will My Catalytic Converter Last?
The catalytic converter is one of the parts in the vehicle that does not go bad so often.
The catalytic converter can las for quite a long time. For instance, if you bought a brand-new car, the catalytic can last up to 100,000 miles, if not more, without needing to repair it.
Usually, the catalytic converter has very minimal problems, and if you had to replace it, you do not need to worry about it for a couple of years.
Therefore, if you are planning to get the catalytic converter cleaned, make sure to deep clean it to save yourself time and effort since you might not need to open it for a long time.
What Are the Best Catalytic Converter Cleaners?
If you decided to clean your catalytic converter, there are many options to choose from.
However, you need to evaluate each option and see what works best for you.
For example, some catalytic converter cleaners can be pricy but can deeply clean your converter.
Besides, pay attention to what the cleaner cleans in addition to the catalytic converter. For instance, many cleaners will not only clean the converter, but they can also clean other parts like the oxygen sensor, the fuel injectors, and others can help clean the entire exhaust system.

The biggest drawback of this vehicle is that you can only use it for diesel engines. In other words, if your car is not a large truck or trailer, you might need to consider any of the other listed products on this list.
The vehicle’s catalytic converter is responsible for converting harmful car emissions into less harmful gasses.
The catalytic converter can get clogged due to the carbon buildup in the system. Carbon buildup can mostly happen due to high fuel concentration in the air-fuel mixture.
A clogged catalytic converter can reduce the fuel efficiency in the vehicle and might cause the car to emit thick white smoke. In some scenarios, a clogged catalytic converter can cause severe damages that require a full replacement to the part. Moreover, a clogged catalytic converter can cause the car to fail the emission test.
Once the catalytic converter is clogged, you need to use a catalytic converter cleaner to flush the dirt and get the converter’s performance back to normal.
There are lots of converter cleaners’ brands. In this article, we highlighted ten of the most common catalytic converters.
If you want to select the best catalytic converter cleaner that works best for you, you need to pay attention to the price relative to the size of the bottle. Besides, you need to consider the scale of cleaning, does the product clean other parts of the vehicle?
