Removing deodorant stains from linen

[honeychurch]

I wore a beautiful 1960s cream linen blouse and my deodorant has left a faint blue stain. I tried a vinegar and biocarb paste to no avail. Any other suggestions? I've left it soak for a week now and unsure as to what to do next!

Unfortunately vinegar is a dye/colour fixative so you may have inadvertently set the stain in. If the blouse is cream all over I would try a oxycleaner for whites.
