Dust and pollutants can impede fire alarm performance, so try to keep your detectors clean. An occasional light dusting with a dry rag should easily remove any exterior dust, but you’ll also want to perform deeper cleans annually.
To do a thorough cleaning, take the device off of the wall or ceiling, remove the power source, and then gently take off the external casing. Carefully clear out any collected dust using a vacuum attachment, a compressed air can, or a dry cloth—avoiding liquid sprays or cleaners. Once all dust is gone, you can reassemble the detector and place it back on the wall or ceiling.
Fire safety is a vital component of a homeowner’s responsibility. Hopefully you’ll never experience a house fire, but it’s a good idea to be prepared. Follow the steps above to help ensure that your home is as safe as possible, and check out our recommendations for the Best Fire and Smoke Alarms.
