The Eco One is a portable machine that makes a 1 liter batch of hypochlorous acid (HOCl) on site from water, non-iodized salt, and electricity. It uses a platinum-coated titanium cell and runs on 110V or 220V. Use the solution in your usual cleaning routine on barn aisle and stall surfaces, coop interiors, greenhouse benches, walkways, and other hard surfaces in those spaces.
This page is about cleaning those surfaces only. It is not guidance for treating plants, crops, or animals. HOCL sells machines that make HOCl, not bottled HOCl, so you can mix a fresh batch on site from water, salt, and electricity.
Make a batch on site
Fill the pitcher to the 1 L line molded on the pitcher (about mid-height), not to the top. The pitcher holds 1.5 L; the recipe is for 1 L. Add 2 grams of non-iodized salt and the vinegar the manual specifies, replace the lid, and run the setting the manual gives for the strength you need (about 200 ppm takes 16 minutes; up to 500 ppm takes 40 minutes). Check each batch with HOCl test paper (10–200 ppm). For a 500 ppm batch, mix 1 part solution with 4 parts water, test that, and multiply the reading by 5. Empty and rinse after use; do not use a dishwasher.
Use only the salt and vinegar amounts in the manual. Never mix the solution with ammonia, bleach, strong acids or other cleaners; doing so can release chlorine gas.
If someone breathes in fumes or swallows solution, call Poison Help at 1-800-222-1222 (poisonhelp.hrsa.gov).
Benches, aisles, and other hard surfaces
Wipe or spray greenhouse benches and walkways, barn aisle floors and stall walls, and coop surfaces when those areas are empty and you are already doing a cleaning pass. Keep solution out of feed, water troughs and drinkers. Keep the solution on hard surfaces. Do not apply it to plants or animals, and do not use this page as guidance for crop or animal treatment.
How it fits the work
- Mix a 1 liter batch in a utility area, then use the included 8 oz fine mist sprayer on benches, latches, and other tight surfaces.
- For longer aisles or rows of benches, the Eco One + Electrostatic Sprayer bundle adds a handheld, battery-powered sprayer with a 1.8 liter tank. Spray surfaces only, with plants moved off the benches and animals out of the area.
- The Eco One unit is made in South Korea.
- Manufacturer-stated storage: keeps close to 90% of its strength for about 90 days in a closed, light-protected container at room temperature or cooler.
- Store unused solution in a closed HDPE, LDPE or PET container away from light.
- The Eco One weighs 1.3 lbs (0.6 kg), so it is easy to carry between buildings. Full directions are in the user manual on the product page.
