Crusty armpits help

[SecretSpy]

Can anyone tell me the secret of how to get deodorant out of a polyester uniform please?

I generally use Mitchum roll on and now I have stiff crusty patches under both armpits that don't come out it the wash. And they look very attractive obvs

have you tried soaking in cold water with a bit of washing powder over night?
can you wear cotton items instead?

No cotton option as it's work uniform. So far I have tried rubbing it with fairy liquid, or with some laundry detergent, before putting it in the wash but it didn't work.

Maybe the green fairy soap bar is worth a try.

Try napisan that works well at getting stains out. Just put it in with the washing detergent.

soaking the areas in vinegar is supposed to help
