Napisan?

I too wondered about Napisan, or similar, and have in front of me what I use - Sard Wonder Oxyplus (not for nappies though, am well past that stage in life! ) I note though that on the back of the container there is this info':
"Important: Do not use on silks, leather or Woollens. Take particular care with polyester/viscose. "

Good luck glynsmum - I hope that you are able to find an appropriate way to freshen the colour of your top. :-))

Napisan or any of the laundry soakers in a soak overnight and then hot wash - this even seems to work on son's white football socks although they've been soaking since last weekend
