Athena Cleanse – Root Zone & Irrigation System Cleaner

Athena Cleanse is a professional-grade irrigation system and root zone treatment formulated with hypochlorous acid to help maintain cleaner growing systems, healthier root environments and improved nutrient delivery. Derived from salt through an advanced electrochemical process, Athena Cleanse provides powerful oxidative cleaning properties while remaining safe for use throughout all stages of plant growth.

Designed for hydroponic, coco and soil cultivation systems, Athena Cleanse helps reduce mineral scale, break down unwanted organic matter and keep irrigation equipment operating efficiently for longer.

Why Choose Athena Cleanse?

Over time, irrigation systems, reservoirs and growing media can accumulate mineral deposits, scale and organic residues that reduce system performance and impact nutrient availability. Athena Cleanse works to break down these unwanted deposits while helping maintain a cleaner and more efficient growing environment.

Unlike many cleaning products, Athena Cleanse is non-toxic, non-nutritive and can be used safely alongside your regular feeding programme without significantly affecting nutrient balance.

Key Features

  • Powered by hypochlorous acid technology
  • Helps maintain a cleaner root zone
  • Reduces mineral scale and buildup
  • Supports irrigation system maintenance
  • Suitable for all stages of plant growth
  • Very low TDS formulation
  • Helps improve irrigation system efficiency
  • Can be used in hydroponic, coco and soil systems
  • Suitable for recirculating and DWC systems
  • Effective for system flushing and maintenance

Advanced Hypochlorous Acid Formula

Athena Cleanse utilises hypochlorous acid, a highly effective oxidising compound produced through a proprietary electrochemical process. This unique formulation helps break down unwanted organic residues and mineral deposits while remaining gentle enough for use around actively growing plants.

The result is a cleaner root environment and improved system performance without the need for harsh cleaning chemicals.

Supports Cleaner Irrigation Systems

Regular use of Athena Cleanse helps maintain irrigation equipment by reducing scale, mineral accumulation and residue buildup throughout reservoirs, pipes, drippers, filters and irrigation lines.

By helping keep systems cleaner, Athena Cleanse can contribute to improved water flow, more efficient nutrient delivery and reduced maintenance requirements over time.

Ideal for Hydroponic & Recirculating Systems

Athena Cleanse is particularly beneficial in recirculating hydroponic systems where mineral accumulation can gradually affect performance. Regular application helps minimise buildup within nutrient reservoirs and irrigation equipment while supporting cleaner operating conditions.

Suitable for:

  • Deep Water Culture (DWC)
  • RDWC Systems
  • Nutrient Film Technique (NFT)
  • Drip Irrigation Systems
  • Flood & Drain Systems
  • Coco Coir Growing
  • Soil Cultivation
  • Commercial Irrigation Systems

Root Zone Maintenance

A clean root zone is essential for healthy plant development and efficient nutrient uptake. Athena Cleanse helps maintain a cleaner growing environment by reducing unwanted organic matter and mineral deposits that can accumulate within the root zone and growing media.

Regular use can help support stronger root development and healthier growing conditions throughout the crop cycle.

Application Rates

Regular Maintenance

Use 2–5ml per gallon of water as part of a routine maintenance programme to help maintain clean irrigation systems and growing environments.

Heavy Buildup Conditions

For systems experiencing significant mineral deposits or residue accumulation, increase the application rate to 5–10ml per gallon of water.

Propagation & Cuttings

For propagation systems and cutting preparation, use 10ml per gallon of water to support a clean and healthy rooting environment.

Media & System Flush

Apply at 5–10ml per gallon of water when flushing growing media or irrigation systems to help remove accumulated mineral deposits and residues.

Foliar & Surface Applications

Athena Cleanse can also be used as part of a cleaning and maintenance programme for cultivation environments. When diluted appropriately, it can be applied to growing equipment, irrigation components and work areas to help maintain cleaner operational conditions.

Always test foliar applications on a small area before full use.

Best Practices

  • Shake well before use
  • Use clean measuring equipment
  • Follow recommended dilution rates
  • Monitor EC and pH as part of your feeding programme
  • Store in the original container with the lid securely closed
  • Keep away from direct sunlight and extreme temperatures

Why Growers Choose Athena Cleanse

Athena Cleanse has become a popular choice for growers looking to maintain cleaner irrigation systems, healthier root zones and improved system efficiency. Its unique hypochlorous acid formulation helps reduce mineral buildup and organic residue while remaining safe for use throughout all stages of growth, making it an essential addition to modern cultivation programmes.
