I soak in vegetable / fruits into PH 11 water for 10 minutes, and then flush it with clean water, all such said chemicals will be neutralized and washes away.
Some of our C-hing claimed that water and other stuff used in cleaning is much expensive than the cost of veg/fruits !!!
However, please consider if Health is on top of all that mentioned ???
Noway la... for our own heath ma..mama......
