Is the Three-Way Catalytic Cleaner Useful?
1 Answers
For mild three-way catalytic converter blockages, the three-way catalytic cleaner is quite effective. Currently, there are three methods for cleaning the automotive three-way catalytic converter: 1. Additive Cleaning: This involves directly adding the cleaner to the fuel tank to mix with the fuel. When the vehicle starts, the cleaner enters the combustion chamber along with the gasoline, burns, and is eventually expelled with the exhaust gases. As it passes through the three-way catalytic converter, it performs the corresponding cleaning. 2. Drip Bottle Cleaning: Also known as no-disassembly cleaning, this method directly injects the cleaner into the engine via a drip bottle, allowing it to enter the combustion chamber with the air and burn. Similar to the additive cleaning method, it cleans the three-way catalytic converter as the exhaust gases pass through. 3. Disassembly Cleaning: This requires completely removing the three-way catalytic converter and soaking it in oxalic acid for cleaning. This method offers the best cleaning results but is cumbersome, time-consuming, and labor-intensive, making many 4S shops and repair shops reluctant to provide disassembly cleaning services.
