Removing stains from white jodhpurs

[ajph]

I borrowed my friends white jodhpurs for competing in and have managed to stain them with horse poo or something else….Washing has proved useless….Does anyone have any tips on how I can remove these god awful stains before I give them back to her…
Thank you for the help! x

Bucket of bleach, that's what the old school do.

Spray with Ariel stain remover or vanish leave twenty minutes then put some Ariel ( or similar ) not a colour one the green box is using Ariel in and bucket and make a strong solution with hottish water them soak the breeches overnight be sure to fasten them up this lessen the likely hood of rusty marks from the fastenings .
Then wash as normal at 40 in the dirty stuff programmer that should do it .
I would be cautious about using bleach on some else's breeches .
