I used hydrogen peroxide to clean my air pods. Low sound on right none in left

Hello,

Low volume is normally a symptom of needing to be cleaned. You might try again:

How to clean your AirPods, AirPods Pro, AirPods Max, and EarPods

Otherwise, is the volume OK without the AirPods?

For the left one not working, see this:

If your left or right AirPod isn't working

Also consider a full reset:

Good luck.

How did you clean them?

Did you dampen a cloth and wipe the outside down, careful to not get any liquid inside the speakers?
