How do I clean my carbon monoxide detector or CO alarm?

You may vacuum or dust it but should not use any cleaners or paint near the CO alarm.

If you are cleaning with strong solvents such as ammonia you should ventilate the area to protect your health and protect the CO alarm from ammonia.  Ammonia and amines from cat urine can reduce the life expectancy of your alarm.  In normal operation it should last for 6 years.  If it is nearly 6 years old you should replace your alarm with a new one.
