What can I do? I can't wear it until I get rid of the smell.
So far I've put it on a gentle tumble dry to try to evaporate some of the chemicals. It's currently hanging outside in the garden. My other options are to hang it over a hot vinegary bath, put it in a sealed bag with envelopes of fresh coffee for a few days or take it to the dry cleaners but I hate the idea of piling on yet more chemicals.
It's a Burberry Ivybridge trench, so not a £££ Heritage trench. Could I risk a gentle wash?
