Ways of removing small dye or run stains on fabric are different from ways of recovering from a run.
Dip a clean, white cloth in a bleach solution, wring the cloth so it does not drip on the fabric.
Carefully dab the colour stains with the bleached cloth. Avoid dabbing the cloth around the stain.
Proceed in small touches, but quickly: a few seconds should do the trick.
Even if the coloured stains have not disappeared completely, rinse as quickly as possible, using a damp cloth, proceeding in the same way, with gentle touches.
It is better to repeat this process several times than to damage the garment.
