How do I get rid of this stain?

[Maize]

I managed to drop tomato sauce (not ketchup, was with pasta and made from chopped toms etc) down my work uniform last night.

I could not wash it out at work and it didn't end up being soaked or washed until a good 12 hours after I did it.

I have washed it now and the stain is still there (grr). I really need it to fade out.

What can I use to fix it.

My uniform is navy and white striped and its nurses tunic. Thanks!

i would put a blob of washing up liquid on it and give it another wash.

leave it to dry in the sunshine (what sunshine?) and it will help fade anything left.
