I used bleach on my childrens taekwondo uniforms, now they look less white- how do I fix?

I put about half a cup of bleach into the bleach dispenser of my washing machine. I put the worn once uniforms in the wash on cold, now they appear less vibrant, more of a faint tint to them. HELP!!! How can I remedy?|||Some fabrics,even whites,you can%26#039;t bleach. They probably have a small amount of a synthetic in them and bleach will discolor them. Try some of that new OxyClean powder that may help. At least thats what they say it will do.|||Get a new uniform or a white die from rit. Report Abuse
|||add 1 cup of vinegar next time you wash them and they will come out clean and vibrant.
