Of acids, descaling and my sinuses
I love my humidifier. Since buying it a month ago my sinuses have given me a lot less trouble. Leaning over the unit and directly breathing in the hot moist air has decreased my sinus difficulties in a big way. However, while I do love the humidifier I certainly don't love taking care of it. Particularly not the scale that builds up quite rapidly on the thermal unit in the base. Since the humidifier goes through a couple of liters of water--and since my water is from a well with lots of mineral content--a night, there's a lot of mineral salts building up. I need to descale every week. The typical descaling method is to soak in vinegar. Vinegar is mildly acidic having around 5% acetic acid and a pH of around 3. Traditionally vinegar is produced by allowing bacteria to oxidize a fermented solution, typically wine or hard cider. This process takes considerable time, weeks at least and more often months. Some expensive Balsalmic vinegars are aged for decades. That's acetic acid
