How to Use Hypochlorous Acid, the Gentle Cleaner That Works on Almost Any Surface

Bleach is out, and a gentler alternative is now taking over on TikTok. Hypochlorous acid (HOCl), once used mostly in hospitals and dermatology offices, is now having a moment as one of the safest, most effective ways to clean your home. Best of all, it doesn't contain any harsh chemicals, and it won't leave behind any lingering odors.

So how can you use this eco-conscious solution in your kitchen or bathroom? Here, we asked professional cleaners for their insight on this miracle worker.

What Is It?

Hypochlorous acid is a weak acid created when electricity is applied to a solution of salt and water. It's the same molecule that your white blood cells naturally produce to fight off pathogens. So despite its intimidating name, HOCl is one of the safest and most effective disinfectants available today.

“[It] plays a unique and effective role in household cleaning because of its strong disinfecting properties combined with relatively low toxicity,” says Petya Holevich, house cleaning expert and supervisor at Fantastic Services. “It’s effective against a broad range of pathogens, including bacteria, viruses, and fungi.”

Benefits

HOCl’s real magic lies in its versatility and shockingly gentle nature. It works as a disinfectant, deodorizer, and sanitizer without the potential side effects of traditional all-purpose cleaners. You can use it on everything from countertops to toys, and it’s a go-to for homes with kids, pets, or anyone sensitive to harsh chemicals.

Compared to bleach or ammonia-based products, hypochlorous acid is:

• Non-toxic and biodegradable
  
• Safe on skin and gentle on lungs
  
• Free of strong odors or sticky residues
  
• Environmentally friendly—it essentially breaks down into saltwater

Taylor Riley, co-founder of GermSmart Commercial Cleaning, swears by it. “What really sold me was the ability to make it at home,” he says. “It bridges the gap between green cleaning and serious sanitizing.”

How to Use It: Cleaning Fabric

You can use HOCI on some soft surfaces like pet beds, throw pillows, or that mysterious stain on your favorite armchair.

Here’s how to do it right:

• Look for a household-safe concentration. Around 200 ppm is ideal.
  
• Lightly mist the fabric. No need to soak it!
  
• Let it air dry; no rinsing is required.
  
• Always spot-test first if you’re working with dyed or delicate textiles.
  

Don't use hypochlorous acid on materials like unsealed leather or silk. While it’s a very gentle cleaner, repeated use can cause these surfaces to fade or wear over time.

How to Use It: Cleaning Surfaces

HOCl is incredibly utilitarian. Just get a jug, and you’re good to go for almost all of your surfaces. Use it on the spots you touch countless times each day, like kitchen counters, doorknobs, bathroom tiles, phones, and light switches.

Here’s how to apply it effectively:

• Spray directly onto the surface until it’s visibly damp.
  
• Let it sit for at least 60 seconds so it can disinfect.
  
• Wipe with a clean cloth or let it air dry—either works.
  
• If you're cleaning a food prep area, give it a quick rinse after.
