Literally a brand new top bought yesterday, worn last night and got pasta tomato sauce on .  It is a pale lime green colour and I wiped as much of it off as poss then put it in a wash last night... stain still there... soaked it in washing powder and water in the sink for 30 mins this morn... stain still there.... It is 92% cotton, 8% spandex.  It's so annoying!  Any ideas anyone?

Sometimes soaking in cold water then plunging into hot helps remove the stain.

I googled and got this answer back lol

Always make every effort to rinse a stain while still fresh. To remove tomato based sauce stains from clothing, quickly blot as much of the stain as possible from the garment.  Do not attempt to rub in any fashion, as this only embeds the stain further.  Run the stain under running water, doing so from the back side.  This forces the stain back out through the fabric.  Then, rub a little liquid detergent into the stain, being careful to do so gently.  If the garment is white, you can use a bleaching agent such as hydrogen peroxide or white vinegar to further reduce the stain.  Lemon juice is also known to work, too.  Launder the garment per care label instructions. Be sure to check the stain before putting in the dryer.  If the stain is still present, don't dry it - the dryer will set the stain further. If the stain is persistent, use a pre-treatment stick to remove.  Carpeting can be cleaned by flushing the stain with cool water, blotting up excess with a motion from the center of the stain to the outside. Pour a little lemon juice or rub with a slice of lemon to remove stain.  (Be careful on wood!) Flush with cool water, and blot up excess.  If the stain persists, use a wet spotter on the stain.  Cover with an absorbent pad that is moistened with the wet spotter, and keep an eye on the stain.  Keep the pad moist until the spotter has had a chance to eradicate the stain.  Blot clean with cool water and a white cloth to remove residue.

Try it it might help, fingers crossed anyway it comes out

Generally the best thing is to use a good squeeze of 'fairy liquid'. Rub the stuff well in before washing in the normal way. It has always helped me, only thing it cant help if there has been a bleaching of colour, something that i have done and is a complete nuisance.

Thanks for all of your replies...  What started out as a bargain top turned out to be an expensive one after I'd hot-footed down to the shops to get some remedies... I bought both of the stain removers that my supermarket sells, some white vinegar and a lemon.  Did it work?  The first three didn't and that was after trying washing-up-liquid and washing powder rubbed into the stain.  But aha!!! The lemon worked!!  I cut it in half and rubbed it into the reverse side, rinsed it under the tap, hung it on the line (sun shining onto the stained side) and it dried minus the stain yeee!  Thanks guys :-)

magic! thats good :)
