Catalytic Converter Cleaner – Everything You Need To Know

by Conner Mckay

Catalytic converters that work well are not only important but also required to reduce your vehicle’s emissions. However, they may often perform poorly because of the carbon deposit, resulting in less efficient exhaust gas filtering. Using a reliable catalytic converter cleaner might assist you in resolving this issue every time. They are cost-efficient and effective at reducing emissions and improving your vehicle’s overall performance.

Using the best catalytic converter cleaner, you can easily and quickly restore your catalytic converter to good operating order. These specifically developed cleaning products help to remove the dust and debris that has accumulated in the catalytic converter, as well as unclog it. However, you’ll need a good cleaning to achieve the best results.

A catalytic converter collects a large number of particles and other material that is ejected from the engine. This implies it may become clogged and require cleaning (or if you want to learn how to hollow out a catalytic converter without removing it). Here’s what to do about it.

What Is A Catalytic Converter Cleaner

Catalyst cleansers are chemicals that are used in engines to clean or increase the performance of the fuel-air mixture (FAM). Some cleaners and purifiers for air/fuel mixtures are used to clean or enhance the mixture in your engine. They’re described as carefully developed compounds that clean the complete exhaust system, EGR valve, combustion chamber, and fuel injectors, as well as remove and prevent carbon accumulation inside the car.

Catalytic Converter Cleaners: How Do They Work?

A catalytic converter cleaner uses chemical reactions to eliminate the build-up in a car’s exhaust system. This contains the cylinders, fuel injectors, and various exhaust components. Catalytic converter cleaners are solvents that, when added to gasoline, break down the carbon deposits that the fuel mixes with as it passes through a car’s combustion and exhaust systems.

The cleaner breaks down the molecular structure of the hydrocarbon particles simply by coming into touch with them, making it easier for them to be carried out of the exhaust system. As a result, the vehicle’s overall performance improves.

What Causes The Catalytic Converter To Clog

The catalytic converter is an important part of the exhaust system for reducing vehicle emissions. It accomplishes this by using an oxidation and reduction process to turn dangerous pollutants in exhaust gases into less toxic pollutants and water. When a catalytic converter breaks, it must be changed right away.

The conversion of harmful contaminants from the exhaust gas is a complex process. A ceramic monolith with a honeycomb filter structure serves as the converter’s heart (to learn more, check out our guide on what does a catalytic converter look like). On top of the monolith is a precious metal film that intercepts and decomposes the toxins as they pass through the converter at high temperatures (you can confirm this with a catalytic converter temperature test).

Manufacturers promise that a catalytic converter will last the vehicle’s life. Still, it is now commonly known that it will not and need to be replaced at least once throughout the vehicle’s lifetime.

Types Of Catalytic Converter Cleaners

There are so many different types of catalyst cleaners that picking the right one for your engine might be difficult (for more insight, check out our guide on what does the catalytic converter do and what’s in catalytic converters, as well as what are catalytic converters). There are, however, a few types of catalyst cleaners that are suitable for most engines. These are some of them:

1. Ammonia

Ammonia is a powerful oxidant that might harm your catalytic converter. Use this cleanser to restore surfaces that have been oxidized.

2. Lysol Chemical Acid

Lysol chemical acid is a strong halogenide cleanser that can aid with converter cleaning. This cleaner is especially good at eliminating oil or fuel-related build-up on the converter.

3. Carbon Dioxide

Carbon dioxide is a powerful reducing agent that can aid in the cleaning of the converter. Clean regions that have been contaminated by carbon dioxide or other contaminants with this cleanser.

4. Clorox Chemical Acid

Clorox chemical acid is a potent halogenide cleaner that can aid in the cleaning of the converter. This cleaner is especially good at eliminating oil or fuel-related build-up on the converter.

5. Methylene Chloride

Methylene chloride is a powerful organic solvent that can aid with converter cleaning. This solvent also aids in the removal of oils and other impurities from the engine’s interior air.

6. NaClO

Sodium hydroxide, sometimes known as “lye,” is a strong base that can aid with converter cleaning. This cleaner is especially good at eliminating oil or fuel-related build-up on the converter.

7. Spic And Span

Spic and Span is a mild organic solvent that can aid with converter cleaning. This solvent also aids in the removal of oils and other impurities from the engine’s interior air.

Do You Need A Catalytic Converter Cleaner

Before we get into the core of the article, let’s go over some of the advantages of employing an exhaust system cleaning solution. The engine performance will be the first thing you notice after using a cleaning.

Hydrocarbons cling to exhaust components, causing them to malfunction. A catalytic converter cleaner is used in this case to clean the exhaust system and increase engine performance.

When the cleaner activates, it improves filtering performance and reduces the quantity of pollution it emits.

It also improves the fuel efficiency of the engine by allowing it to create greater power with less fuel. No one likes it when the exhaust system emits that rotten egg odor (for more insight, check out our guide on my car smells like rotten eggs). Fortunately, if you apply cleaning, the odor will go away.

Benefits Of Catalytic Converter Cleaners

Here are some of the key advantages that catalytic converter cleaners can provide:

1. Enhances The Performance Of Your Vehicle

When your catalytic converter is unclean, it has an impact on more than simply your car’s emissions. It also reduces the efficiency of your vehicle. In scenarios like starting your automobile from a dead stop or ascending an incline, you may discover that your engine isn’t functioning as effectively as it once did.

2. It Helps You Save Money

You may save hundreds of dollars by extending the life of your catalytic converter, which is one of the most expensive replacement parts. Of course, you’ll have to replace it eventually, but you’ve had plenty of time to save.

3. Air Purification

This is a critical worry because it affects your and your family’s health. When you drive a car with a dirty catalytic converter, the exhaust contains hazardous compounds that can harm your health. This is especially true for persons who suffer from respiratory issues like asthma.

How To Use Catalytic Converter Cleaner

Here’s a quick seven-step guide to getting the most out of your catalytic converter cleaner.

Step 1: Make Sure Your Spark Plugs Are In Good Shape

You might be wondering what spark plugs have to do with cleaning the catalytic converter in your vehicle. However, heavy carbon buildup on your converter is most likely an indication that your vehicle is running rich.

It means the fuel and air mixture is off, or one of your spark plugs isn’t sparking properly. It’s a good idea to change your plugs every now and again, especially if you can’t recall the last time you did.

By thoroughly burning all of the available gasoline, excellent spark plugs help to reduce the amount of carbon buildup on your catalytic converter. You’ll need to consult your vehicle’s owner’s manual to determine the type and quantity of plugs to purchase.

Step 2: Pour In The Cleaner

Once you’ve dealt with your plugs and ensured that everything is in working order, it’s time to empty the contents of the cleaner into your vehicle’s gas tank. Simply empty the bottle into the tank after opening it. Always read the instructions before using anything. So, if your cleaner comes with any specific directions, make sure you follow them.

Step 3: Fill The Tank

Fill your vehicle’s tank until it’s completely full, or around 10 gallons. Look up the suggested fuel to catalytic converter cleaner mixing ratio to figure out how much fuel you’ll need.

Step 4: Drive Till The Tank Is Empty

To receive the best results from the cleaning process, you should drive for at least 50 miles straight after the application. You should drive the car until the tank is completely empty.

Step 5: Inspect The Check Engine Light

If your car’s check engine light hasn’t turned off yet, repeat the procedure. If your vehicle used error codes to warn you of a problem with the catalytic cleaner, now is the time to clear them. Because every vehicle is different, you may need to consult your owner’s manual for instructions on how to clear the codes, or it may be automatic.

Step 6: Refill Your Tank & You’re Done

Fill up your tank and get back to your daily routine, or go check your car’s pollution levels. By now, the cleanse should have come to an end. Remember to clean your car on a regular basis.

However, how frequently you use the vehicle determines the exact time frame. Once a year is sufficient for automobiles that are rarely used, with up to three or four cleaning sessions per year for cars that are used regularly.

Factors Before Choosing A Catalytic Converter Cleaner

Because the cleaner is a type of chemical, there are a few things you should know before purchasing one and pouring it into the engine’s tank.

1. Compatibility

Don’t buy a catalytic converter cleaner until you’ve determined whether it’ll work with your vehicle’s engine. Not all cleaners were designed to work with all sorts of engines. Some car cleaners work with a variety of engines, including 2-stroke, 4-stroke, and gasoline and diesel engines.

On the other hand, some cleaners may be incompatible with specific engine types. Before you buy, check the instructions to see if your engine type is listed among the compatible engines.

2. Capacity Of Bottle

Catalytic converter bottles come in a variety of sizes and capacities. Most fuel tanks require a full bottle of cleaner, though this varies depending on the brand and type of cleaner. One thing to keep in mind is that once the seal is broken, the contents will no longer be effective.

As a result, for a typical 16-gallon tank, the best option is to acquire a bottle of roughly 10-20 ounces. You’ll also find a lot of multipack alternatives in this range. Getting a multipack is highly advised because you may require a catalytic converter cleaner on a frequent basis to maintain your vehicle. They are rather inexpensive, and the small bottles can be used one at a time.

3. Eco Friendly

A catalytic converter cleaner is a container full of chemicals, so you should know how safe it is to use in your automobile as well as how safe it is for the environment if you’re concerned about the environment.

You can check that the cleaner conforms with requirements such as the VOC and OTC regulations, as well as others like the low-sulfur content criteria.

4. Cleaning Effectiveness

The quantity and number of bottles you’ll need are also determined by how well the solution cleans. The best catalytic converter cleaners will not require a large amount of this solution to clean the fuel system.

Catalytic Converter Cleaner

The majority of cleaner bottles come with step-by-step instructions printed on the package. It will also tell you how much cleaning fluid you will need. When making a purchase, make sure to compare numerous possibilities and select the most efficient one in terms of reliability and efficiency.

5. Safety

These aren’t ordinary cleaning products; the bottles are brimming with toxins. As a result, you must determine whether it is safe to use in your vehicle. Also, ensure that the product you purchase is efficient and environmentally friendly.

6. Government Regulations

In several states, using a converter cleaner that fails an emissions test is illegal. State regulations apply to the usage of a catalytic converter cleaner, just as they do to the exhaust system. On the label of the bottle, the creators mention this. If you live in an area where chemical cleaners are not prohibited, however, you are free to use anything you like.

7. Price

Another important element to consider when purchasing a catalytic converter cleaner is the cost. Yes, most of the alternatives are reasonably priced, ranging from $5 to $15. However, you should proceed with caution because your primary motivation for hiring a cleaner is to save money.

If your car fails an emission test or displays a check engine light, the catalytic converter is certainly the issue. If you decide to replace this converter, expect to pay at least $2000.

As a result, using a catalytic converter cleaner is the best option. Compare costs and features before making a purchase. Even more so because you’ll need to use it on a frequent basis to keep your vehicle’s engines in good shape.

8. Complete System Cleaning

A catalytic converter is a part of a car’s exhaust system, not the entire system. Cleaning the converter alone will not give you the solution you need if it becomes blocked and affects other exhaust system components.

As a result, ensure the cleaner can work on important exhaust system components like oxygen sensors, cylinder heads, and fuel injectors. If you believe your car’s problem is restricted to a specific component, though, you might choose a cleaner that specializes in that component.

9. Multipack

Using a cleaner like this is an important part of car care. As a result, you’ll require the cleaning at some point in the future. To save money, purchasing a multipack that included a dozen or more of these cleansers would be great.

It is determined by your financial circumstances. If you have a lot of money to spend on your car, go with the cost-effective multipack choice. There are a range of single cleaners to choose from if you only require a solution for this time period.

Does CataClean Work

As a frequent owner of cars that require work doing at a garage, I know how costly those visits can be. If the problem is something I can fix myself I will always take that opportunity. Cataclean is the newest product that I will be adding to my list.

Cataclean is a fuel system cleaner with over 12 years of independent testing under its belt, which to me cries out for reliability. It is also a straightforward catalytic converter cleaner.

Cataclean Liquid Science for gasoline engines is formulated to detox the catalytic converter. Over time carbon deposits build-up, it’s unavoidable. This build-up limits the gas flow in the exhaust, in turn reducing engine output and efficiency. Not something a driver likes to hear.

What Is Cataclean

Cataclean contains solvents and specially formulated chemicals that remove these catalytic converter deposits with a single application. It is a performance improver, emissions reducer, and efficiency booster. Not to mention a money saver.

Cataclean is in no way limited to gasoline cars. The products are widely used on gasoline, diesel, and hybrids. Cataclean Diesel for diesel engines has the same detox effect on both the catalytic converter and the diesel particulate filter, thus lowering particulate emissions and prolonging the need for a DPF replacement. No matter what you drive, Cataclean has something for you.

Motorcycles also have their own Cataclean product, Cataclean ‘One Shot’ Bike. Brake horsepower, torque, and throttle response all benefit with just one use.

How Does CataClean Work

Well basically if you have a vehicle, Cataclean is going to be worth the purchase.  By using Cataclean and therefore removing the build-up of carbon deposits in the exhaust system, users have seen between 5-10% increase in fuel performance, some even 25%.

Benefits Of Using Catalytic Converter Cleaners Like Cataclean

  • Reduce engine smells –  Over time an engine’s catalytic converter can start to smell like rotten eggs. It is not an attractive smell and can easily be sorted out with the catalytic cleaner.
  • Protect your motor –  To look after your engine periodic cleaning out of the catalytic converter will help ensure that the engine is getting a proper fuel supply and healthy exhaust gas flow. This means that the engine will run smoother, clean, and will cut down on maintenance.
  • Clean pass emission on tests – Yearly emissions tests are essential to make sure you pass every year, a catalytic converter cleaning treatment can help. Cataclean as an example will clean out all the grime, dirt, and carbon from the engine and exhaust system. Helping pass that test every year.
  • Reduce emission levels – Catalytic converters are complex parts of the car’s exhaust system (as with what is the purpose of a catalytic converter), if you are not keeping it clean, then it has no chance of working at its full potential. regular cleaning means it can run at 100%.
  • Improve engine power – You may notice that you are down on engine performance. It could be a simple thing like a gunked-up catalytic converter. A quick clean with a catalytic converter cleaner might get you back running at full power without even touching a spanner.
  • Save cash – You might be able to notice that regular cleaning improves your car’s MPG and will prolong the life of the catalytic converter which can cost a hundred to replace if damaged.

How To Use CataClean

It couldn’t be easier. Cataclean is available in 150 ml bottles for Cataclean ‘One Shot’ Bike or in a larger 450 ml bottle if you’re buying Cataclean Liquid Science for your car. For a single application, you pour the contents of the bottle into a 1/4 full gasoline tank, drive the car as normal for 10-15 minutes and you’re done. That’s it.

As much as one application will benefit your car, Cataclean recommends that you repeat the process 3-4 times a year, just to keep the fuel system at its absolute performance best. If you want to be utterly organized about it, schedule the application before your next service and save on some unexpected fixing costs.

Simple Cleaning Process Steps:

  • Pour the bottle of Cataclean into your tank
  • Drive as normal until the tank is almost empty
  • Clear any OBDII error codes if present
  • Refill with normal fuel
  • Drive on the roads for around 50 miles to re-calibrate on-board computer (OBDII)

How Do Catalytic Convertors Work

For those of you wanting to get technical, here is exactly how a catalytic converter works.

Where To Buy Catalytic Converter Cleaner

The usual price for Cataclean Liquid Science is £15.99; Cataclean Diesel, £16.50; and finally Cataclean ‘One Shot’ Bike, £12. I can say for one that I will be going to my nearest retailer and grabbing a bottle. Of course, that’s for those of us here in the UK. For you folks across the pond State-side, all you need to do is order a bottle of Cataclean in from Amazon. As of writing, a 473mm bottle costs $24.73.

What To Do If My Catalytic Converter Is Clogged

To clear your catalytic converter, you must first determine whether it is clogged. A few signs and symptoms are sufficient to make a diagnosis. However, these symptoms could be as little as a decrease in engine performance, decreased gas mileage, and so on.

So, if you’ve ever considered driving a car without a catalytic converter, the symptoms you’ll experience during its clogging will persuade you otherwise. Of course, this is not the case; a car cannot be driven without the converter. However, using a converter is always risky and not recommended since it might result in various problems over time.

Now, if you’re the type of person who pays attention to even the smallest details, such as a clogged catalytic converter, you’ll be desperate to get rid of it. The good news is that a catalytic converter cleaner may be found in any auto store or online.

The Steps Are As Follows

Step 1: The first step in unclogging the converter is to identify the right cleaner brand for your automobile and engine model.

Step 2: Never begin the cleaning procedure with less than 15 liters of gas. So, don’t drive your car until it’s been cleaned to get the gas content below this range.

Step 3: Last but not least, put the cleaner in your gas tank. It should be poured in such a way that no catalytic cleaner is lost throughout the procedure. Follow the directions on the cleaner bottle to determine how much cleaner to pour.

Step 4: Finally, replace the gas cap and begin driving your automobile for roughly 30 minutes. Drive on a highway if possible to avoid overheating the engine.

Step 5: Continue driving until the tank is empty or nearly empty. You should then repeat the converter reading after clearing the OBD code and letting it calibrate.

This procedure is ideal for a non-clogged catalytic converter.

I’ve used Cataclean diesel to get rid of the rotten egg smell on my Volvo S40. First time it happened it took 1 bottle to sort it out. A year later the problem reoccured and it took 3 bottles. So Cataclean does work for sure. Cheaper than paying for a new catalytic converter.

Scott 02/12/2022 - 8:55 pm

Definitely works!! I have a finicky turbo engine that leans toward a rich gas mixture which kicks off the check engine light & reduces mpg. 1 bottle of Cataclean on a near empty tank, then fill er up, will do the trick. Just be patient as it can take a little time to go through the system.
