We wash all incoming fruit and vegetables in salted water, but lately our usual suppliers (Ocado/Waitrose) seem to have run low, and most of the stuff on the www is overpriced ‘gourmet’ stuff.
Some veg marked 'prewashed' will get washed in a very mild solution of 1% sodium hypochlorite (NaClO) and 16.5% sodium chloride (NaCl; common salt). This is the same solution @ 1:80 dilution that is used to sterilise babies' feeding utensils, including baby bottles. Hardly going to kill you allen is it?
Those veg marked 'wash before consumption' can simply be washed in water. The really nasty things (pesticides and insecticides) are not so much ON the fruit/veg as IN them, as these products are systemic. The only way to avoid consuming these chemicals (all be it in minute quantities) is to eat organic produce.
We sell it here cheap and have plenty of stock and am pretty sure all the other supermarkets here sell it to, even tho we have are firebrake in Wales and therefor a little bit of panic buying last week. Maybe its a London problem allen
