Best Catalytic Converter Cleaners Buying Guide
Choosing the right catalytic converter cleaner can be cumbersome, especially when you come across tons of options. It requires some specialized knowledge to pick the best one for your needs.
Before jumping on any product, you need to consider a few factors to make an ideal choice. Here are some factors that must never be overlooked while making a purchase.
- Engine compatibility
Since different cars come with different engines, you need to pay attention to the compatibility of the cleaner. While many auto catalytic converter cleaners go well with gasoline and diesel engines, some of them are not accurate for certain engines. Similarly, if you are driving a hybrid car, you need to check the compatibility of the cleaner with the engine.
The best way to do so is by looking at the cleaner’s manufacturer instructions. A quick glance will help you find whether a certain cleaner is compatible or not. You can always find a cleaner that consists of a premium blend to work with all types of engines.
The catalytic converter cleaner usually comes in a bottle. Therefore, you need to know how safe it is to use in the car. Similarly, it should be eco-friendly. Make sure to check that the cleaner consists of low-sulfur content and meets the necessary regulations like VOC and OTC.
Though not a critical consideration, capacity is still an essential one. Keep in mind that catalytic converter cleaning is not a one-time job. In fact, you need to do this from time to time. Therefore, it is better to invest in a package that offers a volume discount to bring value to your purchase.
Similarly, don’t go for bigger bottles, as opened once, they tend to lose potency over time.
You will find various cleaners that incorporate additional detergent additives to take the experience to the next level. However, if you drive a regular gas-powered gas, there is no need to invest in something this fancy.
- Full system cleaning
You should know that a good catalytic converter cleaner is also good at cleaning the entire exhaust system, and not just the catalytic converter. Since each part of the system plays an integral role in the overall performance of the vehicle, you should go for a product that offers thorough cleaning. It should offer a good flush to the cylinder, pistons, as well as valves while lubricating them at the same time.
This might be an important consideration for some of you. Believe it or not, renowned brands have an edge in providing some excellent products. They hold a proven history of delivering quality goods for decades. Therefore, it is suggested to go for a well-known brand to enjoy premium quality.
Price can be an important consideration, especially if you are on a tight budget. Just remember, quality always comes at a price. Therefore, set your budget first and then try to pick a model accordingly. Moreover, it is always economical to go for packages instead of a single bottle.
Benefits of Catalytic Converter Cleaner
You might wonder why it is important to invest in a good catalytic converter cleaner. Those who are still struggling to make up their mind for getting a new cleaner should not stop here. We have drawn a list of benefits to convince you. Let’s have a look at them one by one.
- Lower emission levels
A catalytic converter is specially designed to limit the emission of gases in the environment. Since these gases are quite harmful to human health, it is essential to incorporate a good catalytic converter in the vehicle. Meanwhile, you need to clean the system with an efficient cleaner to serve the purpose precisely.
The cleaner not only helps to cut the emission levels of harmful gases even further but also enables you to pass the test easily.
- Improves engine performance
The lost power of the engine can be restored with a catalytic converter cleaner. It is indeed one of the major benefits of this product. The improper combustion of fuel leaves hydrocarbon particles on certain parts of the system. We all know that a gunked-up catalytic converter can highly alter the overall performance of the vehicle.
Adding the catalytic converter cleaner will effectively clean the fuel injection system. As a result, there will be more power production with less fuel. Moreover, it cleans and lubricates the cylinder to cut down on friction, thereby improving the car’s efficiency.
Any debris in the path of exhaust gases can lead to bad engine performance. The catalytic converter literally clears every blockage for ensuring better results.
- Saves bucks
It goes without saying that better engine performance will save you huge bucks because of lower maintenance and fuel costs. Similarly, you don’t have to change the catalytic converter as you can clean it from time to time.
- Reduce bad smell
Any car that has been running for a while tends to develop a rotten egg smell over time. This smell is caused by the build-up in the catalytic converter. So, if your car also has a signature rotten egg-like smell, a catalytic converter cleaner can be of great help. It will remove the smell by cleaning the combustion and exhaust system. Moreover, you don’t have to spend money on replacing the catalytic converter.
- Protect the engine
Another prominent benefit of a catalytic converter cleaner is protection from any damage. Regular cleaning will prevent the engine from damage, thereby keeping the vehicle good on the road. Similarly, proper fuel and exhaust flow ensure a smoother and better operation.
- Pass emission tests
As mentioned above, if you have an old car that needs to go for an emission test, a catalytic converter cleaner will be at your rescue. The high-end formulations can dissolve debris and carbon deposits efficiently. A clean converter means clean emissions.
You will find various features in a cleaner that are peculiar to a certain brand. Different manufacturers offer their modified version of a product. However, you just can’t trust any random brand. You have to be really careful while picking a product to regret any loss in the future.

Now, fill the tank until it’s almost full. It is better to consider the fuel to catalytic convertor cleaning mixing ratio for better results.
- Step 4: Drive around till empty
Once you have completed the above steps, now is the time to drive around your vehicle. It is recommended to drive around for at least 50 miles to achieve the best results. It is even better to drive the car until the tank is empty.
- Step 5: Check Engine light
Your car’s check engine light should go off by now. If it does not, repeat the entire process. Clear all the error codes by consulting your vehicle’s owner manual.
- Step 6: Refill the tank
Finally, fill your tank, and you are good to go. You should also go and check the emission levels.
It is important to clean your car from time to time. Though the exact time-frame depends on the usage of the vehicle, 3-4 cleaning sessions are necessary per year for a car to keep it running at its best.
