Insulation never really dries,not entirely. If you work construction and the builders are an asshole to you, you can always pop a little hole into drywall and pee directly into a wall 🧱
After a day,the urine will become rancid.
There is absolutely no way to get rid of that smell once it’s soaked into the insulation. They’d have to cut out the entire section of the wall and replace it.
I’ve never done this,lol, just something I think about when some punk gets uppity.
Silver lining, I’m get paid hourly to daydream about peeing into a wall.
