When's It DueHow often
How often should you restock laundry detergent?
When the bottle or box is low — typically every 4–8 weeks
Liquid, pods or powder all empty on a wash-count, not a date. Save what you use and mark replaced when the new bottle arrives.

Why replace it
An empty bottle mid-basket is a small crisis with a wet pile behind it. The reminder is the fill line, not a subscription.
Signs it is worn out
- The bottle is on the last pour
- Pods are down to a handful
- You have already borrowed a neighbour’s or a hotel leftover
