Did you try a rinse with distilled water? It may be all the acids, ammonias, etc. in the pee that are causing the trouble.

Open it up, rinse with distilled water, leave out to dry.

My older boy, when he was just 2 1/2 to 3 years, put one of my hearing aids in a glass of water. I was able to dry it out at once and it continued to work.

There's some hope. But not a lot.

BTW (1): try putting phone on lanyard around neck. Only way to immerse it then is to really bend over the toilet, and now why would you want to do that?

BTW (2): I find it easier to sit down. No matter how well you aim, the distance creates splashing, which creates, after time, an unsightly and noisome mess.
