Hi neighbors. To clean the lens on your Ring Cameras or Doorbells, we recommend using a soft microfiber cloth to gently wipe away any dirt or debris. If that doesn’t work and the lens on your device appears to be blurry or foggy, other neighbors in the Community have found success using different methods. I did a quick search and found a few threads you can check out: Thread 1, Thread 2, and Thread 3.
You can give the DIY solutions that worked for the neighbors in those threads a try to see if it works for you. If the concern is that there may be moisture inside of your Doorbell or Camera that is impacting the lens, please give our support team a call at one of the numbers available here. Our support team can review the potential damage and the warranty on your Ring device to determine the best resolution. If you are outside of the US, please visit here to see how to contact support.
