Lasko recommends that owners clean their fans with a mild detergent, which is a household cleaning product. The best method to clean a Lasko heater is to use the brush attachment on a vacuum cleaner without any cleaning product.
Lasko also makes humidifiers. To clean a Lasko humidifier, the company recommends using vinegar to descale it. It also needs to be disinfected, and Lasko recommends using a teaspoon of chlorine bleach per gallon of water. Turn off and unplug the humidifier before filling it with bleach solution. The solution should sit in the humidifier for about 20 minutes, after which the humidifier should be rinsed thoroughly before using.
