SENTINEL Formula 522 Odor Destroyer Block, 5 lbs

Sentinel 522 OB Odor Destroying Blocks are a simple, effective solution for controlling odors and foam inside recovery and waste tanks. Designed specifically for professional cleaning and restoration equipment, these water-soluble solid blocks dissolve gradually to provide continuous deodorizing action while helping reduce foam buildup that can interfere with vacuum performance. Unlike liquid treatments or powders, the drop-in block format requires no measuring or mixing. Just place a block directly into the tank, filter basket, or mesh pouch and let it work automatically during operation. This helps maintain cleaner tanks, fresher-smelling equipment, and smoother airflow. The integrated foam suppression helps prevent excessive suds that can reduce suction or risk overflow, protecting sensitive internal components and improving overall equipment reliability. Available in both 1 lb tubs for smaller crews and 5 lb tubs for high-volume or daily use, Sentinel 522 OB blocks are ideal for carpet cleaners, janitorial teams, restoration contractors, and facility maintenance professionals who need dependable, easy-to-use odor control.
