This is new to me. I will try it next time it might be helpful. Do you have any idea of the reason why it works???
Unfortunately, it prob won't help with the stuff pre-impregnated in the above mentioned clothing. This is diff from what gets in our clothes if someone reeking in scent hugs us or something. It is DESIGNED to STAY IN and GET STRONGER!!!! Quite unlikely to be able to get it out.
Also, I suspect that it was not only perfume, but also something else even more toxic. Since the company won't admit it is there, there's no way to know.
