- vinegar (of your choice - I use white vinegar)
- baking soda
Pour some water into a bowl and add vinegar (half a cup for every litre). In the other bowl pour some water and add baking soda (1 full tbsp. of baking soda for every litre).
1. Put fruit and vegetables into the bowl with vinegar for 2-3 min.
2. Then put them into the bowl with baking soda for another 2-3 min.
3. Wash them in a normal water.
