For use with disinfecting and sanitizing units in internal chutes, this is a one-gallon bottle of cleaning and deodorizing solution for general purpose cleaning. We also sell a four-pack of these bottles at a package discount. A disinfecting and sanitizing unit is sometimes requested for trash, linen, and/or recycling chutes to control odor and bacteria. A unit such as this is generally composed of a reservoir tank and a proportioning valve and is located above the top intake of a chute. This disinfecting solution is injected into the water flow from the flushing spray head system.
