1. Block the drainage hole of the dishwashing sink, fill it with enough water to cover the baking pan, pour 1/2 cup of baking soda and 1/2 cup of white vinegar, and mix evenly. Put it into the baking pan and soak it for about 30 minutes to 1 hour. The oil stain will soften at high temperature, so you can also soak it in hot water. The decontamination ability will be improved. If the oil stain and burnt dirt are too thick, try to extend the soaking time. The previous step Just put the bowl in the sink to soak, and it will be easier to wash it the next day.

2. After the baking pan is soaked, gently scrub the baking pan with a vegetable cloth. It is recommended not to use wire brushing as this may scratch the baking pan, making it easier for dirt to accumulate in the future and even releasing harmful substances.

3. After scrubbing off the charred dirt on the baking pan, wash it slightly with detergent, drain and wipe it dry. Drain the baking soda and white vinegar mixture from the soaked baking pan. When it is dropped, the water pipe can also be cleaned at the same time, which can be said to be an approach that kills two birds with one stone.
