Instead of this pointless hack, the NHS website gives detailed advice on washing all fruit and vegetables.

The official advice says: “Washing will help remove bacteria, including E.coli, from the surface of fruit and vegetables.

“Most of the bacteria will be in the soil attached to the produce. Washing to remove any soil is, therefore, particularly important.

“Wash them under a running tap and rub them underwater, for example in a bowl of freshwater.”
