don’t neglect pre-wash detergent.
Also, use powder/gel over packs/pods so you can use and close the detergent dispensers. You don’t want the portion for the main cycle to get rinsed away with the pre-wash.

The TC video covers that, and also use powder over gel, not only is it more economical but far superior. I forgot exactly, but 2 of the main cleaning agents can’t coexist in a liquid suspension so all gels have to pick which one. They can coexist in dry form so with powder you get the best of both worlds
