How to keep your Nest products clean

In general, you can gently dust the outside of Nest products with a soft, lint-free cloth. If your product needs cleaning more thoroughly, follow the recommendations in this article. In particular, if you have a Nest Protect, this article will show you how to open its back and carefully clean the smoke chamber.

Nest thermostats 

Use this method to clean any Nest thermostat:

  1. Lightly dampen a soft, clean cloth with water.
  2. Wring out any excess water from the cloth.
  3. Gently wipe the display and sides of the thermostat, making sure that no drops of water
    accumulate around the ring or in the grill at the bottom of the display.

Important: Do not spray water directly onto Nest thermostats, or use cleaning solutions or polishes, as doing so may damage your thermostat.

Nest Temperature Sensor

If your Temperature Sensor gets a little dusty, you can:

  • Gently wipe it with a slightly damp cloth.
  • Use isopropyl alcohol if it's really dirty.

Important: Do not spray water directly onto Nest Temperature Sensors, submerge in water or use abrasive cleaning solutions or polishes.

Nest cameras and video doorbell 

Nest cameras come with a coated glass lens that’s engineered to provide the clearest high-definition (HD) picture possible, day and night. But like anything else, the lens can get dirty, which might affect your video. In general, you should treat your Nest camera as you would any other high-quality optic. If it needs cleaning, use a soft, lint-free cloth.

If your video always seems to be out of focus in a particular area, check the lens for debris. Any glare from the sun will also be worse when the lens is dirty.

Important: Do not use paper towels, tissues or rags to clean your camera. These materials can leave lint behind and can even scratch the lens coating. In addition, don't clean your camera with glass cleaner for windows and mirrors, rubbing alcohol or any other household cleaner. These cleaning fluids may contain harsh chemicals and can leave behind residue.

Follow the specific instructions below:

Indoor cameras 

Indoor cameras from Nest include:

  • Nest Cam Indoor
  • Nest Cam IQ Indoor

How to keep your camera clean

  • To clean the body, simply wipe it with a soft cloth to remove any dust or dirt.
  • To clean the lens, gently wipe away any dust with a soft, lint-free cloth. Cleaning cloths for glasses and optics are ideal for removing dust and oily fingerprints without damaging the lens coating. You can also use a compressed-air duster made for electronics.
  • For tougher smudges, such as oily fingerprints on the lens, you can dampen the cloth with a drop of cleaning solution made for cameras, glasses and other optics.

Outdoor cameras 

Outdoor cameras from Nest include:

  • Nest Cam Outdoor
  • Nest Cam IQ Outdoor

Over time, your Nest outdoor camera may collect dust, pollen, water spots and other types of debris from its outdoor environment.

Do not submerge your camera in water or any other liquid.

To clean the lens:

  1. While holding your camera in place, gently wipe your camera's lens with a soft, lint-free cloth. If you like, you can use compressed air to blow off dust and particles.
  2. If there are water marks or other materials on the lens, you can moisten a soft cloth with a little water and gently wipe the lens clean. You could also use a drop of cleaning solution made for cameras, glasses and other optics.

To clean the body, power adaptor or power cables (not the lens):

  1. Unplug your camera from the wall socket.
  2. Moisten a soft cloth with water and a little washing-up liquid.
  3. While holding your camera in place with one hand, gently wipe the surface clean with the cloth in your other hand. Be careful not to get any washing-up liquid on the lens.
  4. Rinse the cloth and then wipe the surfaces again to remove any remaining washing-up liquid.
  5. Plug your camera back in.

Although Nest outdoor cameras are designed to withstand the elements, it's not recommended that you spray one with a high-pressure hose. Make sure that you wipe it down with a soft cloth after cleaning to prevent water spots, which can obstruct your camera’s view.

Nest Hello video doorbell 

Over time, your video doorbell may collect dust, pollen, water spots and other types of debris from its outdoor environment.

Do not submerge your doorbell in water or any other liquid.

To clean the lens and body:

  1. Gently wipe your camera’s lens and body with a soft, lint-free cloth. If you like, you can use compressed air to blow off dust and particles.
  2. If there are water spots or other materials on the lens, you can moisten a soft cloth with a little water and gently wipe the lens clean and wipe down the body. You could also use a drop of cleaning solution made for cameras, glasses and other optics.

Although Nest Hello is designed to withstand the elements, it's not recommended to spray it with a high pressure hose. Make sure that you wipe it down with a soft cloth after cleaning to prevent water spots, which can obstruct your camera’s view.

Nest Protect 

For regular maintenance, simply wipe the outside of your Nest Protect with a soft, slightly damp cloth. If it needs cleaning more thoroughly, take it off the wall or ceiling and follow the steps below.

As with any smoke alarm, dust build-up on the outside or inside of the Nest Protect can stop it from working properly. For example, dust can interfere with the smoke sensor. Dust can get into the alarm during the installation process or build up over time. Nest Protect has been designed to be as maintenance-free as possible, but you should keep it clean. Therefore, as a part of standard ongoing maintenance, you may need to clean the inside of your Nest Protect thoroughly.

Important cleaning tips

Nest Protect sensors can be damaged by common cleaning chemicals, paint or too much water. Please follow these guidelines:

  • Never use detergents or solvents (such as glass cleaner).
  • Don't spray air fresheners, hairspray or other aerosols near your Nest Protect. These chemicals will damage it and can make it non-operational.
  • Don't get water inside your Nest Protect.
  • Don't paint any part of your Nest Protect. Paint will seal the vents and affect its ability to detect smoke and carbon monoxide.

How to clean the smoke chamber

There are different instructions for cleaning the smoke chamber of 1st- and 2nd-generation Nest Protects.

1st gen Nest Protect 

  1. Take your Nest Protect off the ceiling or wall. Just twist it anti-clockwise, being careful to pull and unplug connectors gently if you're cleaning a wired Nest Protect.
  2. Wipe the outside of the Nest Protect with a clean, slightly damp cloth. Don't use soap or solvents.
  3. Place the Nest Protect down on a soft, dry cloth with the Nest button facing down. You can prop one side up to avoid pressing the button accidentally.
  4. Unscrew the back of the Nest Protect. Be careful not to lose either of the screws.
  5. Remove the batteries.
  6. Use a can of dry, compressed air, the kind used to clean computer keyboards. Move the air from one corner of the battery cover to the other in a sweeping motion.
  7. Make sure that you blow into the smoke chamber – the large circle in the middle of your Nest Protect. Carefully blow air all around the chamber. Don't try to remove the smoke chamber itself.
  8. Finish by blowing air across the Nest Protect, just as you did with the battery cover.
  9. Replace the Nest Protect's batteries. Wait a minute, until it says 'Hello, from Nest'. If Nest doesn't speak again, screw the battery cover back on. If it begins to sound an alarm or chirp, you may have to give it another few blasts of compressed air.
  10. Put your Nest Protect back on the wall or ceiling. You may want to dust the area where the Nest Protect connects to the wall before you put it back, just in case.

2nd-gen Nest Protect 

  1. Remove the Nest Protect from the wall or ceiling (turn it anti-clockwise until it comes off the back plate).
  2. Detach the power connector if required.
  3. Wipe the outside with a clean, slightly damp cloth. Don't use soap or solvents.
  4. Place the Nest Protect on a soft, dry cloth with the Nest button facing down. Open the battery compartment door and remove the batteries. The door is designed to stay open until they're all replaced.
  5. Remove the screws and lift off the back.
  6. Gently vacuum the inside. Make sure that you clean all the way around the mesh sides of the smoke chamber (the large metal circle).

Note: Before you put your Nest Protect back on the wall or ceiling, you may want to clean the area where it connects to the wall or ceiling.

Nest Secure (Detect and Guard)

Both Nest Detect and Guard should be cleaned once every month. If the motion sensor gets dirty, the detection range could decrease.

  1. Gently wipe it with a slightly damp cloth. You can use isopropyl alcohol if it’s really dirty.
  2. If your Detect was having trouble sensing motion before cleaning, follow the testing instructions in the Nest app.

Nest × Yale lock 

Use this method to clean your Nest × Yale Lock:

  1. Lightly dampen a soft, clean cloth with water. A mild soap solution will remove oil or accumulated dirt build-up.
  2. Wring out any excess water from the cloth.
  3. Gently wipe the front display, including the sides of the keypad, to remove fingerprints.
  4. Gently wipe the back of the lock, making sure that no drops of water accumulate around the thumb turn and battery cover.

Important: Do not use solvents or abrasive cleaners on any components, as this will destroy the protective clear-coat finish. Avoid products that state on the label that they remove tarnish and rust or that they contain acids or caustic agents.
