Buying Guide

Regardless of the vehicle type, the catalytic converter is a crucial part of the engine. Therefore, you have to be careful in choosing, applying and cleaning the converter all the time. A slight mistake can lead to serious damage for the converter which may cause the engine to stop its functionality. To avoid such circumstances, you will certainly need the best cleaner to apply for the fuel system. There are some specific factors regarding the quality of the cleaner which will surely help you to choose the perfect one.

Compatibility:

You have to determine the type of engine in the first place. Different cleaner suits different types of engines; it mainly varies with the fuel type that powers the engine. Apart from that, some cleaners are found to be more suitable for particular engines. In this case, you have to make a careful observation as wrong or unsuitable cleaner can jam or damage the exhausting system.

System Condition:

Here, system condition refers to the current condition of the converter and exhaust. If the engine suffers from medium and low carbonization or deposition of soot, you may choose a cleaner with moderate power. You can also lower the concentration of a powerful one. But the removal of heavy and thick deposit will require powerful and considerably concentrated action.

Complete Cleaning:

A good cleaner must clean all the system path at once. Whether the preferred one can do the cleaning for all the fuel system path is, therefore, an important consideration. Apart from a catalytic converter, a perfect cleaning agent should clean the valves, oxygen sensors, carburetors, injectors, and even combustion chamber to some extent. You have to ensure that at least partial cleaning of these parts is possible with the chosen one.

Composition:

The formulation ingredients of the cleaner also have great importance that directly influences safety as well as environmental contamination. You must check and confirm that the cleaner doesn’t contain any toxic chemical that may cause environmental pollution. In this case, you better find something that is approved by a renowned standard.

Safety:

A safe application requires considerable attention when it is about applying and cleaning manually. In general, the formulation is quite harmful to human skin and eye despite containing no toxic chemical. Though it is more related to your caution and careful working, you need to ensure that the cleaner can be applied safely. And in case the formulation makes skin contact, there needs to be recommended a remedy to minimize the damage.

Emission Reduction:

One important benefit of using catalytic converter cleaner is its ability to reduce emission from the engine. Continuous emission not only hampers the functionality but also decreases the life of engine with increased fuel consumption. Reduction of emission ultimately leads to low fuel consumption with better serviceability. Therefore, you need to ensure that the amount of reduced emission is quite good.

Multipack:

There are two types of cleaner concerning available packs. The single packed cleaner can or can’t come with sufficient quantity to treat the converter. Therefore, you may need to buy lots of single packs to meet the required amount. On the other hand, multipack cleaner offers quite a lot amount at once to work with. It is, therefore, economical to some extent to use a multipack cleaner rather than lots of single pack formulations.

Cleaning Interval:

How often does the catalytic converter require cleaning? Not to mention, it completely depends on cleaner concentration, efficiency, and type. But normally, a catalytic cleaning needs to be for about 2 – 4 times a year. With a powerful one, 2 or even 1 cleaning session per year holds well enough for the fuel system.

FAQs (Frequently Asked Questions)

Question: What is the best catalytic converter cleaner?
Answer: The best catalytic converter cleaner should possess sufficient power to clean the entire fuel system. And it needs to have an environment-friendly composition that will cause no harm or pollution. Apart from that, a good cleaner should wipe out the thick deposit of carbon and residue. Considering all these, the Cataclean catalytic converter cleaner among our choices is indeed the best one.

Question: How to clean with catalytic converter cleaner?
Answer: Using the cleaner is indeed a simple and easy task. You need to take out the cap and enter it into the chamber to pour the cleaning agent. But the tank should be filled with around 4 gallons of fuel which may vary according to model while pouring. The applied cleaner will blend with the fuel by itself inside the tank. Then you need to start driving for about 10 miles or unless the tank becomes empty. Once the tank becomes empty, fill it with regular fuel and drive. You will certainly experience less emission with a smooth engine.

Question: What causes catalytic converter problems?
Answer: As the burned gas triggers carbonization, the catalytic converter starts to get clogged which eventually blocks the path of gas removal. In fact, it raises the deposition of carbon with other nasty particles. Though the problem comes with simple cleaning treatment, the consequence of the clogged fuel system can provide a long-term effect on the entire system.

Question: Does catalytic converter cleaner work?
Answer: Application of converter cleaner mainly removes the particulates and also, different pollutants from the fuel system. Though the converter is completely ineffective for the failed catalytic converter, you can use it for jammed engine or converters that loses its efficiency to a great extent.

Question: Where to buy catalytic converter cleaner?
Answer: You can rely on online shopping sites based on Amazon, Walmart or eBay to get a good-quality cleaner. You can also directly make your order from these sites. Apart from that, you can go to a nearby auto parts store that sells automotive parts.

Question: How does a catalytic converter cleaner work?
Answer: A catalyst inside a ceramic chamber is provided to trigger a proper chemical reaction with the presence of fuel. The burning of hydrocarbon fuel leaves a residue that gets trapped and therefore deposits inside the fuel flowing path. The cleaner mixed with the fuel doesn’t participate in the burning, rather it starts reacting with the deposit.
In general, hydrocarbon burning leaves some specific composition for the trapped residue. The cleaner containing particular formulation breaks the composition of the deposit. Thus, it dissolves the soot or carbonized deposition in the fuel system that leaves the system with the continuous functioning of the engine.

Final Words!
