How do I clean my Razer mouse?

We cannot say with certainty what type of dirt and debris may be on your product, or how certain cleaning products may react with it, but we have had good luck cleaning Razer products using commonly available monitor cleaning wipes. To clean the body of your Razer mouse, take a monitor wipe and use gentle wiping motions. Do not scrub the surface of your Razer mouse. You can clean the sensor using a Q-Tip lightly coated with rubbing alcohol. Let the sensor dry for five(5) minutes before attempting to use it.


Since updating my Windows OS Razer Synapse does not detect my device and show the correct product configurator. What should I do?

If you encounter this, update Synapse 3 through Settings > Check for Updates. If there is no update available, uninstall Synapse 3 and download the latest installer.

My Razer peripheral will not work properly when used with a KVM switch. What should I do?

We recommend plugging your Razer product directly into your PC. KVM switches are known to cause interruptions in communications between devices and PCs. If your Razer product works when plugged directly into the computer, then it is working correctly, and the issue is most likely due to the KVM switch.


Will my Razer product work on a console via USB ports?

The Razer Viper is designed for PC use. However, note that as of 2018, Microsoft has updated Xbox One to support PC keyboards and mice. Razer Viper will work with games that have allowed keyboard and mouse input. For these games, the Razer Viper will work with basic functions.


  • You can’t use a mouse on Home or within the Xbox user interface while navigating the dashboard.

  • You’ll need to use your controller to configure your mouse. Settings do not support mouse interaction.

  • A mouse will not work in Edge, which already has an on-screen cursor.
