One AirPod is significantly quieter

My left airpod is significantly quieter than my right one. Many many months ago I was walking and it was pouring down rain. My airpods fell out of my pocket and got wet. I grabbed them immediately and tried to dry them off. I later put them on and I could barely tell a difference. Now, its like I can barely hear out of my left airpod. I have to have my full volume up to hear audio when my right airpod is loud. I’ve done several methods. I have reset them many times. I’ve cleaned them with a q-tip. I played those audios that are supposed to get gunk out. I checked my sound balance. I even did the thing where you try to suck the gunk out. I’ve done everything I can. None of it has worked. I have a warranty on them until mid-January.
