Sigh.

It is not its pH that makes urine corrosive, but the dissolved salts
that become reactive. That's why cars that are close to the oceans rust
more quickly than do those in rainy inland locations.

Sooner or later you may get something right. Let me rephrase that.
Sooner or later you may apply a known fact correctly to the situation
being discussed. That urine is more or less neutral, or even more
importantly has little buffering capacity, is true, but that fact is
not relevant to the topic.

with a bit of urea, and a neutral pH.
