Do you use vegetable wash in preparing baby's food or just tap water?

Water and cooking is generally enough to kill germs because the food products you find in Singapore are generally tested to be safe by AVA,, whether they are home-grown or imported. I have a friend who lives all organic and cooks only organic vegetables because they are free from chemicals and non-natural fertiliser. Sometimes when she is abroad and is afraid that she cannot find a supermarket that sells organic foods, she will bring along a small bottle of vegetable wash to prepare both her meals and her baby's. I find that a wee bit too extreme but she is very consistent in her ways, and I do admire her for sticking to her organic ways.
