Hello, I have an iPhone 5s and it got water damaged! It got really hot and I left it in a container. After 2 years of sitting, I want to fix it. Any help will be appreciated!

After 2 years the moister is vaporised but corrosion on the board must be very bad. I think that the chance is very very small that it can be fix, because the corrosion has damage the logic board to much in those years. Good luck if you continue the fix.
