Ecover Zero lasts longer because you actually measure it — overpouring is Gain's real enemy

Ecover Zero costs more upfront, but it actually lasts longer in real-world use because you measure it properly. Mom noticed a bottle lasted two weeks longer than Gain simply because the measuring cap encourages you to use the right amount instead of glugging. Gain runs out faster not because the bottle is smaller but because people overpour — it’s the psychological cost of a wide cap and a habit of eyeballing. Ecover Zero’s real cost advantage is the measuring cap.
