You can eat them directly, most of them are washed and eaten directly, but this is not very safe.

You need to soak strawberries in salt water, because if you don't clean the dirt and bacteria on the rough surface of the strawberries, you're likely to get diarrhea. Using lightly salted water (half a tablespoon of salt in one side of the pot of water) can kill harmful microorganisms left on the surface of strawberries.

Precautions:

1, wash strawberries, do not remove the strawberry tip, remove the tip of the strawberry if the strawberry soaked in water, residual pesticides will be with the water into the fruit inside.

2, also do not use detergents to soak strawberries, these substances are difficult to clean, easy to cause secondary pollution.
