does bleach whiten everything?

Ammonia

I don't use bleach except for cleaning plactic stuff. I use ammonia in the wash for colored or whites. It dosen't break down the fabric and it keeps whites white and colored clothes brighter.

My mom has used this for as long as I can remember and now I do as well

One cup in every wash is all you need!!!!

Bleach is a chemical compound derived from organic components used to whiten fabric. Bleach works via the ability of oxidation, or the alteration of a compound via the creation of oxygen molecules. A stain is largely a chemical compound, and the addition of bleach breaks down the molecules into smaller factors so as that it separates from the fabric. Detergent and the agitation of the washing gadget speed up the cleansing technique. The disinfecting properties of bleach artwork interior the comparable way—germs are broken down and rendered danger unfastened via the creation of oxygen. In marketplace, diverse varieties of bleach are used to whiten components mutually with paper and wood, in spite of the undeniable fact that maximum bleach is used to launder textiles.

Bleach is a corrosive substance and doesn't whiten things per say rather than that it breaks down things. So it will break down the dyes in the shirt along with the fabric.

you can try washing it inside out... if its an emblem / design that isn;t sewn in then you will be fine... if its a threaded print it will bleach out the color from there too... so I wouldn't use bleach... plus it wont necessarily white the colored spots it can turn them other colors like yellow.
