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 between-stay cleaning routine on hard surfaces: counters, bathrooms, floors, and other frequently used hard surfaces in a short-term rental.
HOCL sells machines that make HOCl, not bottled HOCl. A compact unit lets a cleaner mix a fresh batch at the property, instead of hauling a bottled product from stay to stay.
A 1 liter batch between stays
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).
Hard surfaces, kitchens, and bathrooms
Work through the unit in the same order you already use for turnover: kitchen counters and sinks, bathroom fixtures, tables, floors, and other hard surfaces guests use most. For a degreasing solution on kitchen film or similar residue, the Eco One can use food-grade potassium carbonate in place of salt. A 100 g sample is included with the machine. Don't combine salt and potassium carbonate in one batch. This page covers hard-surface cleaning only; it is not guidance for laundry.
How it fits the work
- Mix a batch at the property, then use the included 8 oz fine mist sprayer on counters, fixtures, and other tight surfaces.
- For a larger unit or more floor area, the Eco One + Electrostatic Sprayer bundle adds a handheld, battery-powered sprayer with a 1.8 liter tank. Spray surfaces, not the air.
- 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 in a turnover kit. Full directions are in the user manual on the product page.
