We recommend that, at the very least, you include everything from the so-called Dirty Dozen wash in the appliance. These include strawberries, nectarines, apples, grapes, peppers, cherries, peaches, pears, celery and tomatoes. For fruit and vegetables in the Clean Fifteen Or, for organic produce, a thorough rinse under the tap is sufficient. There is no point in cleaning produce with a thick skin, such as bananas, oranges, kiwis, onions, mangoes, pineapples, melons or avocados. The appliance is only suitable for whole (leafy) vegetables and fruit. It is better to peel conventional potatoes; they do not need to be treated with the AquaPure. We recommend eating organic potatoes with their skins on. You can treat these, but it is not strictly necessary if you eat them with a brush Wash them thoroughly under the tap beforehand. Mushrooms can absorb moisture, so it is advisable not to treat them. Incidentally, mushrooms are on the ‘Clean Fifteen’ list, so it is not strictly necessary to wash them thoroughly.
