getting smell of turps/whie spirit out of cardigan

A bit by the by. But I have several children, and eventually, by the time they had reached their teens, I gave up on trying to get stains out of anything,even favorite items.

I used to give it one go only after that, and if it hadnt shifted or needed more time and effort, I gave up on it. I decided that the time and effort for the sake of a very few items a year just wasnt worth it. I found the giving up was very satisfactory!

Thank you. By dint of lots of washes and addition of conditioner the smell has reduced.

Neat Fairy liquid, rubbed gently in and then wash as usual.

You could try a hydrogen peroxide solution. Scroll down this link, it says 50%hp and 50% vinegar for some odours.

I once used it on some jeans where I'd spilt some oily liquid from kippers in a bag and it worked.

I think hanging it in the fresh air might do it suey.. maybe , worth a try.
