options to repair AirPods Max?

I bought AirPods max from Amazon in March 2023. I don't have apple care. They may have liquid damage but I'm not certain. I tired to clean the cups because of sweat stains and maybe the water got inside I'm not sure. The lights work and flash but when I try to connect them to my iMac they say connection rejected and a lot of the time in bluetooth I just got the spinning wheel and they don't connect at all. The sound doesn't work. The cups and headband are are also a bit stained still.

do I have any options to send them to be repaired? or will I just have to buy new ones?
