I want to disinfect the part of my window-unit air conditioner that is exposed to the outside. I’ve always been worried about Legionella in air conditioners. I have used a shark steamer several years in a row to clean this part of my AC unit. I figured the extremely hot steam would kill bacteria on contact. Was I right?
You are thinking and trying to find an innovative solution using logic. And your hot steam may kill bacteria. However, despite conventional wisdom, air conditioners are not a source for Legionnaires’ disease.
