The expression "clean up your act" means to improve your behavior or situation, especially if it is messy or unacceptable. It is often used when someone needs to make positive changes in their life, such as stop doing something wrong, correcting bad habits, or becoming more responsible. For example, if your friend is always late for work, you could tell them to "clean up their act" and start being on time.
