the engine check light will come back on after a while

When you read the fault code on the car’s dashboard when the engine check light is on, for example – P0420, P0430, if you wash the stone filter and use it, it can only be used for a short time, and the engine check light will come back on after a while. According to these fault codes, it means that the stone filter has expired (the stone filter is already damaged).

If the stone filter is clogged with dirt, then you can use stone filter cleaner (or carbon cleaner) to clean the stone filter. If you don’t have these solutions, you can also wash the stone filter by using a household academy ceramic rust remover. Some friends also saw that they took apart the stone filter. (There are some negative effects of separating the stone filter and using it).
