I've just washed some of ds1's school shirts twice using persil and using a prewash the second time.
Zilch effect, the collars and cuffs are filthy and there are random grass stains too.
These are brand new, super ultra non iron ones from M&S that he has probably worn about 3 days each.
He's just started secondary and I am almost in tears of despair. I can't afford to keep replacing them every few weeks.
What do I DO?
