Geerpres® 304 stainless steel buckets have rolled, open rims that reinforce the bucket and prevent accumulation of dirt and bacteria. Exclusive seamless construction keeps buckets leak-free and easy to sanitize. Bail ears are positioned below rims to avoid interference with wringer placement. Three-inch stainless steel (greaseless) casters allow ease of movement as well as sanitation. With proper care and maintenance, these buckets can provide a lifetime of corrosion-free use and will retain their clean, attractive appearance. To prevent the spread of infection (nosocomial infection), many infection control experts prefer stainless steel over plastic because they know it is the only true surface which resists germs and provides no true surface support for the growth of microorganisms. The entire bucket is autoclavable.
