Athena Cleanse
Athena Cleanse – Root Zone & Irrigation System Cleaner
Athena Cleanse is a specialist root zone and irrigation system treatment designed to help maintain clean growing environments, reduce mineral buildup and keep hydroponic equipment working efficiently.
Formulated using hypochlorous acid (HOCl), Athena Cleanse provides powerful oxidative properties in a mild, easy-to-use liquid solution. Produced through a controlled electrochemical process using salt and water, hypochlorous acid helps manage unwanted organic residues, mineral deposits and biofilm within irrigation systems and growing environments.
Whether you're using a recirculating hydroponic system, drip irrigation, coco coir or rockwool, Athena Cleanse can help maintain cleaner irrigation equipment and a more consistent root zone environment.
Suitable for use throughout the growing cycle when applied according to the manufacturer's recommendations, Athena Cleanse is particularly useful in systems where mineral deposits, blocked drippers and organic buildup can become ongoing problems.

What Is Hypochlorous Acid?
Hypochlorous acid (HOCl) is an oxidising compound produced through an electrochemical process involving water and salt. It is widely used in carefully controlled formulations for cleaning, water treatment and hygiene applications.
Unlike conventional acidic descalers, the main action of hypochlorous acid comes from its oxidative properties. These properties allow it to react with certain organic compounds and unwanted residues.
In hydroponic growing systems, this can help manage organic buildup and maintain cleaner irrigation equipment when the product is used at the recommended concentrations.
Athena Cleanse has been developed specifically for horticultural applications, providing growers with a convenient way to incorporate hypochlorous acid into their system maintenance routines.
Why Use Athena Cleanse?
Over time, hydroponic and irrigation systems can accumulate mineral deposits, organic residues and biofilm. These deposits may develop inside reservoirs, pipework, pumps, filters and dripper heads, potentially affecting water flow and system performance.
Regular maintenance with Athena Cleanse can help reduce unwanted buildup and keep irrigation systems operating more consistently.
Clean irrigation equipment is particularly important in automated growing systems, where restricted water flow or blocked drippers can lead to uneven feeding and inconsistent moisture levels.
Athena Cleanse can also be useful in recirculating systems, where the same nutrient solution passes repeatedly through the reservoir, growing containers and irrigation equipment.
How to Use Athena Cleanse
Athena Cleanse can be used at different concentrations depending on the application and condition of the growing system.
Always measure accurately, follow the current manufacturer instructions and ensure the product is diluted correctly before use.

| Media & System Flushing | 1.5–2.5ml per litre |
| Foliar Application* | 95ml per litre |
| Surface & Equipment Treatment* | 95ml per litre |
*These are the supplied manufacturer application rates. Foliar and surface treatments should only be carried out where supported by the current product label and applicable UK instructions. Test foliar applications on a small area first.
Regular Irrigation System Maintenance
Recommended dosage: 0.5–1.5ml per litre of water.
For ongoing system maintenance, Athena Cleanse can be added to irrigation water at the recommended dilution.
Regular use helps manage the accumulation of unwanted residues within reservoirs, irrigation lines, pumps and drippers. This is particularly useful for systems that operate continuously or use automated feeding schedules.
Maintaining clean irrigation equipment can help support consistent nutrient delivery and reduce the need for frequent manual cleaning.
Using Athena Cleanse in DWC & RDWC Systems
Deep Water Culture (DWC) and Recirculating Deep Water Culture (RDWC) systems require careful management of water quality, dissolved oxygen, nutrient concentrations and root zone conditions.
Because nutrient solution is continuously circulated, organic residues and deposits can accumulate in reservoirs, connecting pipework and other system components.
Athena Cleanse can be used as part of a regular maintenance programme to help manage unwanted buildup in these systems.
Its oxidative properties are particularly useful for growers maintaining clean, low-organic nutrient solutions.
Important: Athena Cleanse is not a substitute for adequate dissolved oxygen, correct water temperatures, good reservoir hygiene or appropriate nutrient management.
As an oxidising treatment, it may also be unsuitable for systems that rely on deliberately introduced beneficial microorganisms. Check compatibility before combining it with microbial inoculants or biological root treatments.
Athena Cleanse for Drip Irrigation Systems
Drip irrigation systems are especially vulnerable to deposits forming inside narrow irrigation lines and fine dripper heads.
Over time, mineral precipitation and organic residues can restrict water flow, potentially causing uneven irrigation between plants.
Using Athena Cleanse as part of a regular maintenance routine can help manage deposits and reduce the likelihood of buildup affecting irrigation performance.
For heavily blocked equipment, physical cleaning or replacement may still be necessary.
Athena Cleanse for Cuttings & Propagation
Manufacturer-listed dosage: 2.5ml per litre of water.
Athena Cleanse can be incorporated into suitable propagation and cloning system maintenance routines.
Clean propagation equipment is important because young plants and freshly taken cuttings can be particularly sensitive to poor water quality and unhygienic growing conditions.
The manufacturer also describes a diluted treatment for fresh cuttings. Always follow the current product instructions before applying directly to plant tissue, and avoid assuming that treatment will prevent disease or guarantee successful rooting.
Clean tools, suitable humidity, appropriate temperatures and good propagation practices remain essential for successful plant establishment.
Using Athena Cleanse During Flushing
Recommended dosage: 1.5–2.5ml per litre of water.
Athena Cleanse can be used during a system or growing media flush to help manage residual mineral deposits and unwanted buildup.
This may be useful when changing nutrient programmes, carrying out system maintenance or addressing excessive salt accumulation in a growing medium.
The treatment can be used during vegetative or flowering stages where appropriate, provided the application follows the manufacturer's recommendations.
For growing media with high salt concentrations, always monitor runoff EC and use an appropriate flushing procedure. Athena Cleanse does not replace the need to physically remove excess dissolved salts through irrigation and drainage.
Surface & Equipment Maintenance
Manufacturer-listed dilution: 95ml per litre of water.
Athena Cleanse is also described by the manufacturer for certain surface and equipment cleaning applications.
Maintaining clean cultivation areas, irrigation components, filters and equipment can help reduce unwanted residue accumulation and support efficient system operation.
Before using Athena Cleanse for surface cleaning, check the current product label for the intended application, suitable materials and any required precautions.
Please note: Do not assume that a horticultural cleaning product is approved as a disinfectant or biocide for every surface or application. Follow the applicable UK product instructions and never mix hypochlorous acid products with other cleaning chemicals.
