I bought htis white top from Walmart

SINCE I don't follow directions well i would probably put it in a light bleach water & see if that didn't help. I don't know of anything else that would hekp. I use bleach in alot of things. There are detergents that claim they have bleach in them but i still add blrach to my white clother, towels etc. GOOD LUCK, HOPE U ARE HAVING A NICE DAY. JO

There is a washing detergent that claims it whittens and its not bleach. I don't remember the name of it but have seen it in commercials. I'd use that...if you can find out what it is.

I have never seen or heard of anything like that before. I think you would still be able to use colorsafe bleach when washing it. Colorsafe bleach is alot safer than actual bleach.

Lemon juice, vinegar, or dish detergent. Good luck! Lemons are a natural way to whiten clothing and linens. Let your clothes soak in a sink basin with hot water and lots of lemon slices for an hour or two then launder as usual. Another option for more dingy clothing is to boil water, turn off the heat and add the clothes in a large pot with lemons. Then, let them soak overnight. You will not only get your garments white they will smell lemony fresh as well. Dishwasher detergent is another great whitener for your laundry. Add about ¼ cup dishwasher detergent to your whites and wash them in warm water with your regular detergent. The whitening agent from the dishwasher soap will work its magic and you will have clean, bright whites as a result. White vinegar is another whitening alternative. Pour ½ to 1 cup of white vinegar in your white clothes along with your detergent. The vinegar will not only whiten your clothes, it will help clean out any residue from other detergents or soaps, and it also aids in softening your fabrics. You may get a faint smell when you open your washer, but after you dry your clothes, any trace of vinegar odor will be gone. One more idea that was used quite often before the invention of the washing machine and chemical cleaners is old-fashioned sunshine. While this method may not be as powerful as other whitening methods, it was used quite often by pioneers and early settlers. Sunlight helps brighten whites and keep them smelling fresh. http://www.ehow.com/how_2184890_whiten-clothes-using-bleach.html
