I’m aware this sounds weird. DH has been working mad hours since lockdown and I’ve been ironing his clothes as I’ve had more time than him. He has this one pair of black jeans that, even when just washed, have a waft of stale urine all over them when I put the steam iron on them.
I remember having a pair of black jeans myself with a similar smell but DH’s are worse for this. It’s as if it’s from the dye. He’s definitely not pissing in his jeans. 
I have had a strong sense of smell ever having the kids so maybe this is why I’m noticing this and he’S never mentioned them smelling weird.
Has anyone else found this with denim? I press the steam button, there’s a waft that you think “hmm, odd smell....” then the last bit of the smell is “woah, 🤢”
It is definitely similar to stale urine. What the hell is it?!
