How to Remove Dirt from the Catalytic Converter?

[MacJuliet]

There are two methods to clean dirt from the catalytic converter: 1. Although there are various cleaning agents available on the market, oxalic acid solution is widely recognized by car owners or repair shops for cleaning, and the effect is also very noticeable. However, this method requires disassembling the catalytic converter, and there are certain requirements for the dilution ratio of the oxalic acid solution and soaking time. Improper use may damage the internal structure. 2. The second method is a non-disassembly cleaning, which involves using a "drip bottle" or adding a cleaning agent to the fuel tank. However, this method is less effective than the first one and is suitable for mild clogging of the catalytic converter.
