Clothesline Fresh Anti-Chlor is an additive for eliminating chlorine carry-over in commercial laundry applications, which also reduces fabric damage by chemically neutralizing the residual chlorine bleach in the washing process. Certain types of stains, especially medicinal stains (i.e. iodine, betadine) can only be removed with a reducing bleach. These types of stains are unaffected by chlorine bleach.
