A new, cited post every weekday: the science of hypochlorous acid, studies explained, head-to-head comparisons, and practical guides for every setting.
Studies Explained
Contact Time: Why the Label’s Wet Time Matters
Why disinfectant labels specify a wet (contact) time, what happens when sprays dry or are wiped early, and where to find the number that actually applies to your product.

Dental Unit Waterlines: Biofilm, CFU Limits and What CDC and ADA Recommend
CDC and ADA recommendations on dental unit waterline biofilm, CDC’s recommended limit of ≤500 CFU/mL heterotrophic bacteria for routine dental treatment water, manufacturer IFUs, monitoring and surgical irrigation.

Gyms and Combat Sports: Cleaning and Disinfecting Mats and Shared Gear
Surface cleaning and disinfection for gym mats and shared gear, framed around CDC MRSA athletic-facility guidance and CDC ringworm prevention—using a registered product for the target organism and its label contact time.
Comparisons
HOCl vs Bleach: Same Chlorine Family, Different pH
How hypochlorous acid and household bleach relate chemically, why pH changes kill rates and shelf life, and where each tends to win or lose.
Comparisons
HOCl vs Quats: Non-Enveloped Viruses, Spores and Hard Water
A balanced comparison of hypochlorous acid and quaternary ammonium compounds on non-enveloped viruses and spores, and how hard water affects each—drawn from CDC guidance and peer-reviewed studies.

Hotels and Vacation Rentals: Turnover Cleaning and Norovirus
A turnover cleaning-and-disinfection workflow for norovirus risk in hotels and vacation rentals, based on CDC cleanup guidance and EPA List G—using a product registered for norovirus and its label contact time.
How-To & Safety
How On-Site HOCl Generation Works
A brand-neutral explainer of electrolyzing salt and water to make hypochlorous acid on site: the chemistry, what must be monitored, and EPA device rules.
Science
How pH Affects HOCl
Why pH decides whether free chlorine is mostly HOCl, OCl⁻, or chlorine gas—and why the working target for hypochlorous acid solutions is pH 5–6.
How-To & Safety
How to Store HOCl
Why hypochlorous acid loses strength over time, and how closed containers, light protection, cooler temperatures and chlorine-compatible plastics slow that loss.
Myths vs Evidence
The “Kills Everything” Myth: HOCl’s Real Limits
A myth-check on what hypochlorous acid does not guarantee—organic soil, concentration decay, light and air, pH drift, contact time, surface type and hard-to-kill microbes such as spores—and what affects how well it works.
How-To & Safety
Never Mix: Chlorine Gas, Acids and Ammonia
Why mixing bleach or other chlorine cleaners with acids or ammonia can release chlorine or chloramine gas—and what U.S. poison-center and CDC sources say about the hazard.
Glossary
ppm, FAC and Total Available Chlorine: What the Numbers Mean
A plain-English guide to ppm, free available chlorine (FAC) and total available chlorine—what test strips report, what they don’t, and how to read high-range results.
