<human>: How many times should I wash my hands before I wash my face?
<bot>: It is recommended that you wash your hands at least 20 to 30 times a day. However, it is important to keep in mind that the number of times you wash your hands will vary depending on how often and for what purpose you are washing them. For example, if you are washing your hands after using the restroom, then you should wash your hands more frequently than when you are simply cleaning up around the house or preparing food.
