When it comes to maintaining your car, don’t overlook the catalytic converter. This crucial part helps reduce harmful exhaust gases. To keep it in top shape, choose a catalytic converter cleaner with the right qualities. Here’s what to look for:
- Compound Quality: Opt for a cleaner with a strong chemical composition, like high levels of PEA (polyetheramine), which effectively breaks down deposits and enhances cleaning.
- No of Units: Look for multi-pack units to extend shelf life and provide value, as you may not need to clean the converter more than a few times a year.
- Quantity: Also, consider the quantity per bottle; a typical 16-ounce bottle covers up to 16 gallons of fuel.
Maintaining catalytic converters is challenging due to dirt and chemical buildup. Use specialized cleaners and consult our “Buying Guide” and reviews to choose based on user feedback and comparisons.

Buying Guide For The Best Catalytic Converter Cleaner
Cleaning your car’s catalytic converter is really important. Over time, these converters fall prey to oil, rust, dirt, and many other types of impurity buildup. So, the efficiency of a catalytic converter will surely decrease since it can’t perform well with these layers of impurities blocking its paths. In a lot of cases, it also causes the “check engine” light to turn up which would usually indicate a problem with the engine but is because of excessively harmful exhaust.
And your vehicle could also fail the emissions safety check if the catalytic converter is not working properly. Therefore, you should get a decent catalytic converter right now and make sure that your catalytic converter is in the best shape possible. To help you find the best option, we have prepared this helpful buying guide. Here, we will discuss some important properties of a catalytic converter and help you find the perfect one for your needs.
1. Compatibility
The very first thing that you need to ensure before buying a catalytic converter cleaner is whether it is compatible with your car’s engine or not. While it may seem a little far-fetched, some cleaning solutions are compatible with a narrow range of engine variants and can cause issues when paired with others.
However, if you are using a gasoline car or a bike, then you should not worry yourself too much. Almost all catalytic converter cleaners are compatible with gasoline engines. But, the compatibility issue arises when it comes to hybrid or diesel-powered engines. So, we will recommend going through the manufacturer’s instructions for the cleaning solution and checking whether it is the right option for your engine or not before making a choice.
2. Cleaning Capacity
Even though you are looking for a catalytic converter, there are a lot of options on the market that can treat many other parts of your car along with the catalytic converter such as the exhaust system, carburetors, sensors, inlet, and exhaust valves, manifolds, etc. Since all of these parts are interconnected and are dependent on each other, a problem with one part will start creating problems with others as well.
So, it would be ideal if you get a cleaning agent that has a wider cleaning range and can effectively treat all of these other components along with the catalytic converter. Such cleaners can significantly reduce carbon emissions and replenish the health of many different parts of the exhaust system. And with that, you can not only get a cleaner exhaust from your car, but also increased fuel efficiency and overall better vehicle performance.
3. Quantity
A catalytic converter cleaner is in a liquid form and ships inside bottles of various capacities. So, there are a lot of options available around us in terms of quantity and the total volume of cleaning liquid available in a set. However, you need to keep in mind that you will most probably have to use an entire bottle when you are treating the catalytic converter of your car. While the required volume may vary based on various brands and their compound density, the bottles are usually designed to be used all at once.
Also, keep in mind that these cleaning agents do not have a very long shelf life. So once the seal is broken, you will have to utilize the entire volume of the cleaning agent as soon as possible. So in terms of quantity, we will suggest going with a smaller capacity option if you are treating only one car or a bike. You can also get a set of multiple small bottles for future use. However, if you are planning to get multiple vehicles treated at the same time, you should go with a larger option that offers 10 to 20 ounces of the fluid per set. For an average 16 gallons fuel tank, you will need about 10 to 15 ounces of cleaning agent approximately.
4. Compound Efficiency
Lastly, we will suggest you check the overall efficiency of the chemical before you make a choice. It also affects the quantity of the fluid you need as well as the frequency of cleaning sessions you need with the said catalytic converter cleaner. Generally, an ideal solution for a catalytic converter cleaner does not require any additives and can be used right out of the bottle.
Plus, with a premium quality solution, you won’t need to use a higher volume to get better results. When it comes to the overall quality and instructions regarding the chemical quality of the cleaning agent, you should choose one that ensures the best results in order to keep your catalytic converter in the best shape.
You will also find detailed instructions on the packaging of the catalytic converter cleaner about usage guidelines and preferred quantity based on your engine type. So, make sure you consider this factor before you decide to buy a catalytic converter cleaner.
Frequently Asked Questions
Ans: Using a catalytic converter cleaner is pretty simple and you can definitely use the cleaning agent without needing a mechanic or any sort of professional help. However, you need to know how to unclog a catalytic converter before you can use the solution.
To use the solution effectively, follow these steps:
* Take out the seal of the bottle and empty the cleaning agent into the fuel tank
* Take the vehicle out for a ride and drive it around for 15 to 20 minutes to evenly spread the solution to all parts.
* It is important to have your fuel tank at about ⅓rd of its capacity for effective results.
Ans: A slightly impure or problematic catalytic converter would not cause a lot of problems to the operation of the car or its engine. You can still use your car but there will be a constant indication of the “check engine” light on your dashboard, signaling problems with the catalytic converter. However, it can cause serious problems down the line and can even cause blockage of exhaust gasses completely, preventing your car from starting at all. The excessive back pressure can also damage the internal components of the engine.
Ans: A catalytic converter cleaner works with a mixture of gasoline to effectively clean the internal parts of the engine as well as the converter. And for that, the mixture of gasoline and the cleaning solutions should be balanced. And using a catalytic converter cleaner with a full tank can cause problems with that. For best results, you should pour an entire bottle of 10 to 15 ounces of cleaning solutions in a 16 gallons fuel tank when the tank is at about ⅓rd of its capacity.
Conclusion
Today, we have discussed the best solutions available out there for a catalytic converter cleaner.
