I drowned my 3DS XL in orange juice.?

Around August of 2015, I bought a Nintendo 3DS XL. Today, I drowned it in orange juice. Not on purpose, just that a bottle leaked in my bag where my DS also happened to be. Hilariously enough, out of all the other things in my bag at the time, including clothes, that was the only thing ruined. But anyways, when I bought the thing, I didn't get the warranty the nice man at Target offered me because I didn't want to spend the money and I honestly did not think I would need it. I realize now that I've made a huge mistake. So I guess my question is, do I have to replace it or can something be done to fix it?

I should also mention that I think it's too late to put it in a ton of rice as the DS was wet for probably 5 or 6 hours and the damage had already been done so I don't think that will help.

Thanks in advance.
