These things are the bain of my life. I've just had to replace ds white polo shirts yet again as they are ruined with white board markers. Aibu to ask the teacher to get the kids to wear an old t-shirt ( which we were required to provide ) when doing messy activities? I can't afford to keep replacing t-shirts. This is not just one or two small marks which I could live with it's several big marks. I've even asked ds if he or his friends are deliberately doing it to each other but he says no.
If anyone has any stain removing tips for markers I am more than happy to try anything
