Ugh. In an attempt to look a bit more put-together I spent a bit more than usual on a really lovely, good-quality white t-shirt. It developed yellow stains, which I am fairly sure are from sunscreen. They are not coming out and I am determined not to give up on the newish expensive t-shirt.
So far I have tried:
soaking in Napisan
washing in biological powder
hanging to dry in the sun
It's hanging in my garden in the hope that ongoing UV exposure will fade it but it's been three days and there's still a clear yellow mark.
Any magical remedies, please?!
