A household runs more gently when unfinished chores are discussed before they become accusations.

Chores turn into evidence when they go unspoken. Nobody mentions the bins, the laundry or the dishes for three weeks, and then it emerges as a summary of somebody’s character rather than a request about tonight. By that point the other person is defending themselves instead of helping. The task was small, and the delay is what made it about something else.

Raise the undone thing while it is still just a thing, in one sentence and with no history attached. Ask for the specific job rather than for a change of attitude.
