Laundry problem

[lil75]

I have washed all my fellas shirts this morning and used persil liquid....my fella sweats quite a lot and it is though the washing liquid has reacted with the sweat and has turned the armpits Orange!!! I have washed them again using something else, but I cant seem to get rid of the orange stain!!! Anyone got any ideas on how to get rid of it, and what has caused this to happen...thanks!

Is the Persil liquid a BiO or NON-BIO cleaner??
Sweat stains are a Biological stain and may need a Bio liquid or Powder cleaner to remove them.
Just a thought!!

Soak the shirts in white vinegar (NOT malt!) then wash on a hot wash.
