Continual cleaning that adapts to facility needs.

Trench Clean is a time-release± cleaning product that can be used at any point of a trench or slot drain. Prevention is always the best practice—Trench Clean makes it easy and adaptable.

Trench Clean is a time-release± polymer block with cleaning agents in its pores.

When water contacts the surface, Trench Clean activates specialized cleaning agents to maintain drains. A polymer block, suspended by a high-quality knit fabric, is anchored in place by a durable Shock Control Disk secured above the trench grate or slot drain.

  • Adaptable
  • Use where it's needed most
  • Easy to use
  • Cleans 30 days
  • For trench and slot drains
  • Install Trench Clean at any point of the drainage system for continuous cleaning that helps prevent buildup, pooling, clogging, and foul odors.

    Dirty trench and slot drains present risks for businesses that process or prepare consumable goods. Moisture and a continual source of organic matter make drainage pipes a prime surface for biofilm formation. Buildup can lead to pooling, clogging, and cross-contamination, which exhausts company resources. Trench Clean releases cleaners in the presence of water to help prevent buildup and promote a clean environment.

    Available in EPA Registered or Green Certified

    Place Trench Clean in the desired position and secure it from the top using the Shock Control Disk. In narrow slot drains, slide Trench Clean in from the drain opening and position it near the source of water entry. Each Trench Clean lasts 30 days, providing an effective, time-efficient solution for trench and slot drains. Where the Shock Control Disk isn’t feasible, Trench Clean can be secured with the provided zip ties.

    Physical Characteristics

  • Flexible polymer block covered in a knit fabric
  • Maintains size and weight in water—will not shrink or dissolve
  • Secure fitment
  • Remains where it is secured in position
  • Easy to replace—remove the old block and place a new one
  • How does Trench Clean work?

    Trench Clean has a non-dissolving polymer core that contains cleaning detergents in its pores. When water flows into the trench and over the block, the pores release a small amount of cleaning detergents. This water-activated, time-release± system cleans each time water passes over the product, keeping the trench clean for 30 days. When it’s time to replace, simply remove the old Trench Clean and place a new one.

    Installing Trench Clean

    In trench drains, open the grate at the desired location. Place Trench Clean, pull the empty fabric through the grate, then secure with the provided Shock Control Disk or rubber grommet.

    In slot drains, place Trench Clean into the drain at the nearest opening. Pull the extended fabric to the top of the slot, slide to the desired location, then secure with the Shock Control Disk or zip ties as appropriate.
