I noticed a very strange odour coming from a wicker basket of (rarely worn) clothes in my bedroom recently. It smelled like rancid cooking oil with a pronounced chemical bouquet (for want of a better description).
Anyway, after much detective work, I found a synthetic top buried deep in the basket that absolutely reeked of the above stink. Also, the top felt damp and greasy to the touch, as if it was starting to decompose. Note that all the clothes (including the pongsome top) were put away clean and dry so it wasn’t a case of true dampness causing the problem. And it was only this top, but of course the stink had contaminated other clothing as well.
Are there particular synthetic mixes in clothing that can start to degrade like this?
