This is really silly, but I bought this top second hand and it smelt so bad at first. I gave it a gentle cold hand wash but even after that it didn’t take the smell out, I then smothered it in washing powder and tried to hand wash again.
Unfortunately, the jumper seems to have absorbed all the powder and while it doesn’t stink anymore, it has slightly reduced in size when dry (not when wet) but leaves a film of product when touched.
I have tried to carefully wash it with cool water over and over, tried to use vinegar to pull the product out, but nothing seems to work. It is too sudsy, and the soap seems to have absorbed into the jumper and it doesn’t wash out very easily.
I’ve tried online guides but this is a very specific issue and nothing seems to work, any advice would be appreciated. Many thanks!
