Cleaning Your Smoke Alarm

Most of us have added changing the batteries in the smoke alarms to our yearly to-do lists (and if not, add it in NOW!). But do you clean yours at least yearly? Dust and cobwebs can significantly impact the effectiveness of your smoke alarm, so protect your family and give it a thorough vacuum on the outside, and a good spray with compressed air (like you use to clean computer keyboards) on the inside.
