Washing grapes

Hi folks! SE loves eating grapes. However, he finds the skin of the grapes bitter(I used to soak it in vegewash and salt before this). Thus, each time he eats it, he will either peel the skin himself before eating or ask us to do it for him. Now with Biosafe, I will wash the grapes with it and tadaa SE will happily eats his grapes without peeling. And the grapes are so sweet! Look at this before and after picture..the water is so murky that I have to throw the water away even though it is said the water can be reused 20 times (wash).
