i have to wear white polo shirts to work 5 days a week. they are adjectives white, but have the company logo on the sleeve, which is a bright red. My shirts are looking a little dingy and want to brighten them up, but using bleach will discolor the logo/ any guidance how to brighten them up without risky them? and please dont say go and get new shirts, im lucky i hold 5 shirts, some people solely have 1 to use adjectives week.

thanks
Use Oxi verbs. This stuff works great. Gets stains out and everything.


I use borax and vinegar. Our whites stay white and the colors are still bright. Add 1/2 cup borax to the wash. Add 1/4 cup white vinegar to the rinse. The vinegar smell dissipates as it dries.

Borax is what population use to use on cloth diapers to remove stains, whiten and kill germs.
