How to Use Three-Way Catalytic Converter Cleaner?
2 Answers
The usage method of three-way catalytic converter cleaner is the same as adding ordinary fuel additive, simply pour it into the vehicle's fuel tank to mix with the fuel. After the vehicle is started, the cleaner will enter the combustion chamber along with the gasoline and eventually be discharged with the exhaust gas. When passing through the three-way catalytic converter, it will perform the corresponding cleaning work. Currently, there are two main cleaning methods for the three-way catalytic converter: additive cleaning and intravenous bottle cleaning. 1. Additive cleaning: Additive cleaning involves adding a dedicated three-way catalytic converter cleaner to the fuel tank. After the vehicle is started, the cleaner will enter the combustion chamber along with the gasoline and eventually be discharged through the exhaust pipe with the exhaust gas. When passing through the three-way catalytic converter, the cleaner will perform a certain cleaning effect. Advantages of this method: affordable price and easy operation. Disadvantages: the cleaning effect is very limited. 2. Intravenous bottle cleaning: Intravenous bottle cleaning is currently the most mainstream method and is strongly promoted by 4S shops and repair shops. This method connects a soft tube to the engine vacuum tube and uses the negative pressure in the hollow tube to suck the cleaner in the intravenous bottle into the engine. When discharged through the exhaust pipe, it cleans the three-way catalytic converter. Advantages of this method: convenient to use and good cleaning ability. Disadvantages: relatively expensive. 3. Tips for cleaning the three-way catalytic converter: Whether it is additive cleaning or intravenous bottle cleaning, the cleaning effect on the three-way catalytic converter is not very high. If you want a more thorough cleaning of the three-way catalytic converter, you can only remove it for cleaning. However, because this method is relatively troublesome, time-consuming, and labor-intensive, general 4S shops and repair shops do not provide disassembly cleaning services.
I usually enjoy maintaining my car myself, and using a catalytic converter cleaner is quite simple. Generally, you just buy a bottle of cleaner and pour it directly into the fuel tank—it's safer to do this before refueling. After pouring it in, start the engine and let it idle for about 20 minutes. This allows the cleaner to flow through the exhaust system and clean the catalytic converter. Safety is crucial: make sure the car is cold to avoid burning your hands, and it's best to do this in an open area. After using it, I noticed the exhaust pipe flows much more smoothly, and the emissions test becomes easier to pass. Regular cleaning can also prevent carbon buildup and extend the lifespan of the parts. It's recommended to do this every six months for the best results—it's cost-effective and saves a lot of hassle. Just remember to choose a reputable brand to avoid counterfeit products.
