The kitchen brush is a collective term for brushes of various sizes that are used for different tasks around the kitchen. Some kitchen brushes are associated with sanitary cleaning, while others are used in food preparation. Historically, the kitchen brush was composed of a wood handle and a selection of bristles made with stiff natural fibers. Today, the typical kitchen brush features a durable plastic handle and stiff bristles that are composed of nylon, polypropylene, plastic or brass.
