Do I still need to use a bleach whitening detergent with Koh Sensitive Laundry Liquid?Updated 13 days ago

Typically bleach based whiteners are used to bleach back the whites that have become dulled and grey over a number of washes as the textiles reabsorb dirty water during the wash cycle, Sensitive Laundry Liquid protects whites from this reabsorption of dirty wash water meaning bleaching agents are no longer required.
