"Another issue to consider regarding facial hair cleanliness is keeping food out of your beard or mustache while eating and drinking. For those new to wearing facial hair, this is something to keep in mind until you have developed good habits. After finishing a meal, be sure to discreetly wipe or comb out any crumbs or items that have made their way into your facial hair. Certain styles may be more prone to collecting food than others, so use caution and good judgment-- especially when trying to impress someone on a date, in the office, or at a formal event."
