While very few (if any) Catholics who attend Mass on Ash Wednesday choose not to receive ashes, no one is required to receive ashes. Similarly, anyone who receives ashes can decide for himself how long he wishes to keep them on. While most Catholics keep them on at least throughout Mass (if they receive them before or during Mass), a person could choose to rub them off immediately. And while many Catholics keep their Ash Wednesday ashes on until bedtime, there's no requirement that they do so.
Wearing one's ashes throughout the day on Ash Wednesday helps us remember why we received them in the first place, and it can be a good way to humble ourselves at the very beginning of Lent, especially if we have to go out in public. Still, those who feel uncomfortable wearing their ashes outside of church, or those who, because of jobs or other duties, cannot keep them on all day should not worry about removing them. In the same way, if your ashes naturally fall off, or if you accidentally rub them off, there is no need to be concerned.
Far more important is observing the rules of fasting and abstinence, because Ash Wednesday is a day of strict fasting and abstinence from all meat and food made with meat.
