How to clean new walnuts and how to clean them when playing walnuts.

1. First, soak walnuts in clear water for about 10 minutes to soften them. Start cleaning them with a brush. According to the cleanliness of walnuts, choose hard brush or soft brush.

2. Brush repeatedly, so that the walnuts will fade off the glue attached to the surface, showing a true background color. Wipe the washed walnuts with dry paper towels and cotton swabs to absorb the water on the surface. Take a proper amount of alcohol with a brush and gently brush off walnut mold.

3. Dry walnuts in the shade to avoid cracking in a ventilated place. It takes two to three days to dry thoroughly. Thorough and timely drying can prevent walnut from being attacked by mold and growing dark spots that are difficult to remove.
