The Small Family secret to getting whites their whitest is Biz. It is more effective than the oxi's and much gentler than bleach. I add it to the detergent when washing regular loads. But it really proves its worth as a pre-soak. I use it on everything from linen sheets to Oxford shirts and Hanes T-shirts too, of course, Smalls panties. It works great on stains and that yellowing that comes with age. My new-fangles washing machine doesn't let me soak clothes, so I fill up my kitchen sink with hot water and ass the recommended amount of Biz, and let it sit overnight. Oftentimes I let if soak for a few days. I just keep checking it. Sometimes I rinse it out and start with fresh water and Biz and let it soak some more. If a few days og Biz won't make it white, it's just never going to get white.
