According to the Health Protection Agency (HPA), windscreen-washer tanks can be a breeding ground for the bacteria that causes Legionnaires’ disease. In a recent pilot study conducted by the HPA, scientists discovered traces of the Legionella bacterium in one of five windscreen-washer reservoirs filled with plain, stagnant water. Thankfully those reservoirs topped up with an additive-based screenwash showed absolutely no sign of the harmful, disease causing bacteria. Basically these finding conclude that people who spend a lot more time behind the wheel of a motor vehicle (taxi drivers, couriers etc) are 20% more likely of contracting the rare disease. To lessen the chances of infection, leading bacteriologists suggest that you only fill your windscreen-washer reservoir with a reputable screenwash additive (see below) available from most reputable petrol filling stations.
My word, what next?
