How it's used
This idiom carries a strong sense of protecting family reputation and maintaining social boundaries. It is often used as a piece of advice to younger family members to prevent them from sharing embarrassing or negative household secrets with friends or colleagues. While it reflects traditional values of privacy, it can also be used critically to describe someone who is being overly secretive or defensive about their family's flaws.
Examples
Keep family matters private, don't go around talking about them.

Common mistake
Learners often mistake this for a literal description of hygiene or physical waste. It is strictly a metaphorical expression about reputation and privacy, so using it in a context related to actual cleaning or sanitation will cause confusion.
