Bird shit all over white blouse help

[Judystilldreamsofhorses]

Can anyone please help? I wore a lovely new white cotton embroidered blouse yesterday, and today a bird (I assume an eagle or even a pterodactyl by the state of it) shat all over it when it was on the washing line. I spot washed it in the sink and that removed the worst, but even after two washes in the machine it is still stained and definitely not wearable. Is there any miracle cure? (It’s only been worn once, so I would really like to save it if possible!) pic of pre-bird assault attached.

I soak in Borax powder from Savers. I live on a seagull flight path so I have been bombarded when walking up to my front door and straight away put my clothes to soak in Borax.
Last week I got my new shirt stained, washed it and like you could still see it so soaked and rewashed and hung it on the line in the sun. I hang it in the corner where they don't reach. Usually brings it out.

I’d hang it back out in the strong sunshine and see if that fades it. Sunlight is amazing for most biological stains. Might take a day or two, and you’ll have to hope whatever it was doesn’t make a return trip

Amazing quick responses, thank you so much. I’ll try and pop in past Savers tomorrow and also stick it out on the line again first thing. Bloody birds!

Easy one that. Rinse in cool water. Rub on a Marseille stain bar, leave 30mins. Wash as normal.

I rinsed, rubbed in washing up
liquid, left it for about half an hour, but even after two cycles in the machine it’s still stained 😔. We go again tomorrow.

I feel like the blonde is cursed because the day I bought it I was caught in a torrential rain storm and green dye from my tote bag ran into it. It’s been washed so many times, yet only worn once.
