The Best!
Today was the first time I used Biz on my white bath rugs.  They weren't getting as white as they used to be.  But after using Biz, I could REALLY tell the difference! Since I have a front loader, I used 1 tablespoon with my powder detergent. ( I think 1/2 cup of anything  is too much for HE washers).  Well there really was difference.  But as far buying on Amazon, it is very high priced.
