I’m new here 🙋‍♀️ and I’m working through a big box of Arm & Hammer with OxyClean powdered detergent

From searching the sub, do I just add Biz to each load (in the drum) until I get through this box? Some threads mentioned Biz + OxyClean but it already has OxyClean so assuming I don’t need to add more.

Thanks in advance!
