One of our technicians recently did some troubleshooting of a customer’s Nest Protect smoke/CO2 alarms and determined that, unfortunately, they’d all been ruined because they weren’t protected from the dust and debris of a remodeling project in the home. Dust buildup on the outside or inside of a Nest Protect can stop its sensors from working properly. (The Nest Protect has 6 different sensors: Split-spectrum, carbon monoxide, heat, humidity, occupancy, and ambient light.)
In addition, a Nest Protect's sensors can be damaged by common cleaning chemicals, paint, or too much water. So, be sure to take steps to protect your Nest Protects when needed and to clean them periodically as well.
Here are some tips:
To clean the outside of a Nest Protect: Wipe with a soft, slightly damp, lint-free cloth.
To clean the smoke chamber inside: Take the Nest Protect off the wall or ceiling and follow the steps detailed on Nest’s website that correspond to the model you have. (On Nest's website, click on Nest Protect, scroll down, and choose the model you have - 1st gen Nest Protect or 2nd gen Nest Protect.)
