Norovirus is killed by chlorine bleach at 1,000–5,000 ppm and by EPA-registered disinfectants that explicitly list the virus on their label.
For the full breakdown, see our best Cleaning Products For Norovirus guide.
Norovirus spreads fast through surfaces, and most household cleaners do nothing to stop it. The answer to what cleaning products kill norovirus comes down to two categories: chlorine bleach mixed at the right concentration, or an EPA-registered disinfectant carrying the virus name on its label. Alcohol sprays, standard wipes, and hand sanitizers are not effective against this particular pathogen, so knowing which products actually work matters every time someone in the house gets sick.
Bleach: The Only Ingredient Proven To Kill Norovirus
Chlorine bleach (sodium hypochlorite at 5.25–6.15%) is the disinfectant the CDC relies on for norovirus. The virus is non-enveloped, meaning alcohol and most quaternary ammonium compounds can’t break through its shell — bleach can. To work, the solution must stay wet on the surface for 10–20 minutes (CDC cites 5 minutes as a minimum for some scenarios).
Never mix bleach with ammonia, vinegar, or other cleaners — toxic gases result.
| Surface Type | Dilution (Bleach to Water) | ppm Target |
|---|---|---|
| Food-contact items (utensils, toys) | 1:250 (1 tbsp per gallon) | 200 ppm |
| Standard nonporous surfaces (counters, sinks, tile) | 1:50 (1/3 cup per gallon) | 1,000 ppm |
| Heavily contaminated areas (vomit, stool, porous surfaces) | 1:10 (1⅔ cups per gallon) | 5,000 ppm |
Before applying bleach, remove visible vomit or stool with paper towels and discard in a sealed plastic bag. Apply the solution, keep the surface wet for the full contact time, then rinse with clean water — especially on food-prep areas.
Which EPA-Registered Products Actually Kill Norovirus?
The EPA maintains an official registry called List G of disinfectants that are proven to kill norovirus. Any product that does not appear on this list or does not say “norovirus” on its label should not be trusted for this job.
Several Lysol products are on List G, including Lysol Disinfectant Max Cover Mist and Lysol All-Purpose Cleaner. Clorox models such as Clorox Disinfecting Bleach and Clorox Clean-Up Cleaner + Bleach are also listed. Other verified options include Force of Nature, Oxivir wipes (hydrogen peroxide–based), and OxiClean Disinfectant.
Conventional hand sanitizers do not work against norovirus — washing with soap and water for at least 20 seconds remains the standard for hand hygiene.
Disinfectants That Won’t Stop Norovirus
Quaternary ammonium products that are not specifically EPA-registered for norovirus also fail. “Splash-less,” scented, or concentrated alternative bleaches alter the required dilution ratios and should not be substituted.
Bleach at 5,000 ppm can damage porous surfaces and wood; always rinse thoroughly. Ventilate the area during use. The CDC’s norovirus prevention page provides cleaning guidance for home and healthcare settings.
Bottom line: stick with fresh bleach solution at the right dilution or an EPA List G product. Skip the alcohol sprays and standard wipes when norovirus is the target.
FAQs
Does hydrogen peroxide kill norovirus?
Some hydrogen peroxide–based products are effective if they appear on EPA List G. Oxivir wipes and Clorox Professional Hydrogen Peroxide Cleaner Disinfectant are both registered for norovirus. Standard drugstore hydrogen peroxide at 3% is not tested or listed for this use.
How long does bleach stay effective after mixing?
A bleach-and-water solution mixed for norovirus disinfection loses potency within 24 hours and should be made fresh each day. If you need to store it, double the concentration (2,000–10,000 ppm) and use within 30 days. Write the mixing date on the bottle.
Does Lysol spray kill norovirus?
Only specific Lysol products that carry norovirus on their label and appear on EPA List G — such as Lysol Disinfectant Max Cover Mist and Lysol All-Purpose Cleaner — are proven to kill the virus. Regular Lysol wipes and standard sprays that do not list norovirus are not reliable for this purpose.
