Every sign has a story

Yeah.

@the_turtle @catsalad Once had a portable DVD player where the instructions had the specific callout "Do not urinate on and dispose of the battery in a fire."
"And", not "or"...
@f00df4ce
So I can urinate on it, or I can dispose of it in a fire, I just can't do both. Noted.

some TV-sets in Malaysia have a specific "beware of cat urine" warning (the same set in other countries does not have this!)

It might be because Malaysian folk are increasingly rehoming stray cats, of which a portion of wildcat hybrids with the Asian leopard cat (basically a low foundation number Bengal) and whilst they can be good pets might be a bit wilder..

Interesting. From what I gather, in addition to the normal electrolytes and such, cat urine is extra high in urea (as you could guess by smell) because their kidneys are very efficient, urea is hygroscopic, and moisture in the air breaks that down to ammonium which is conductive and quite corrosive.
@f00df4ce @vfrmedia @ozzelot @catsalad cat whiz will pretty much corrode anything. "Stainless" steel? Bullshit, cat pee will eat right through it.
@f00df4ce @vfrmedia @ozzelot @catsalad 18 years ago I damaged my lungs pretty seriously cleaning up cat whiz (overspray from a catbox in a corner) with a bleach solution in a powered floor cleaner, which released a shitload of pure chlorine for me to breathe. 18 years later, all that damage has finally just about healed.
@the_turtle @vfrmedia @ozzelot @catsalad Yeesh, that's awful. I had a similar concern cleaning recently but didn't think there would be enough volume to be a factor. I guess I was lucky to find peroxide and enzyme based cleaners first.
As regards the metal, ammonia/ammonium are typically fine on stainless up to industrial temps, but apparently the chlorides in the urine are what make it so aggressive as it removes the protective chromium oxide layer, and without oxygen exposure that doesn't reform. Plus despite having uricase, a purine heavy diet means uric acid is still present among all the other stuff.
Was not expecting the cat biology/metallurgy rabbit hole, but kinda fascinating.

@f00df4ce @vfrmedia @ozzelot @catsalad when you can see the actual Green Death, there's enough volume.

Bleach is still really effective at breaking up cat whiz, though. Outside.

@the_turtle
It is effective at breaking it up inside too, except it will also break you up...
