Iphone xs water damage

I had ran my phone under a little water and soap to clean it I made sure to avoid the charging port, I then left it out of its case for about an hour to make sure it was dry. When I went to go put it back in its case I saw that there was some water inside the back camera. I saw it was almost died so I tried to charge it and it didn't work. I tried a different outlet and charging cord and still nothing. I dropped my phone in a creek a several months ago and every thing was fine and normal and that was defiantly more water than this.
