This doesn’t even seem like the most egregious “weird warning”.
Thinking you can use a pet urine cleaner for fibres on a shaggy dog isn’t madness, it’s just “nope, actually a skin irritant”.

It can be funny when the legal department’s Cover-Your-Ass labelling conflicts with marketing.

“My dirty pet was in the car, so…”

Ive heard about the dog owner who washed thier dog, and used the microwave to dry it. Didnt end well.

What’s wrong with it?
