ODOR-BOSS triple-action deodorizers from Chemisphere are formulated with three odor-eliminating agents and other high-performance ingredients to eliminate odors at the source. Winter and summer syrups are formulated to neutralize the toughest odors caused by bacteria and organic matter. They are easy to use, with a strong masking color. They are free of formaldehyde and nonylphenol ethoxylates (NPE), with a long-lasting effect. They will not damage a recirculating flush system, but keep drains and pumping systems clean using a detergent. They will protect metal, rubber and plastic parts of vacuum trucks. They are noncorrosive, nonflammable and non-staining. 877/426-9557; www.chemisphere.com.
