Ds started school last week, he did two days. The two jumpers he wore are absolutely filthy! I know everyone says they get messy but they really are pretty bad. It's paint and mud mainly and the Vanish stain remover I used one the first one hasn't got it out. I'm starting to think that the 3 jumpers I bought was hopelessly optomistic but at £14 each I was hoping to manage. Any top stain removing tips?
