Try soaking in vanish before for a few hours and then wash on high with vanish
My mum friends at older daughters school, swear by hanging clothes in the sun to make school T-shirts come clean xx
Agree with Jane, let vanish sit in the clothes before washing x
Hang them out in the sun, it bleaches all the stains away 🥰
Vanish for a little bit then soak in napisan for as long as you can then just a normal wash
I soak in napisan wash and then put in the sun! Even just put out in the sun after washing makes a huge difference!!
