FAQs
Can 3 % hydrogen peroxide be used on all surfaces?
It works best on hard, non‑porous surfaces; porous materials may absorb the liquid and reduce effectiveness.
How long should the peroxide stay wet to be effective?
A minimum of five minutes of contact time is needed for a >3‑log reduction of norovirus on clean surfaces.
Is hydrogen peroxide safer than bleach for households?
Generally yes—peroxide is less corrosive, has a milder odor, and is less likely to damage most countertops.
Can I use hydrogen peroxide as a hand sanitizer?
No. The CDC recommends soap and water; peroxide can irritate skin and isn’t proven effective on hands.
Do higher concentrations work faster?
Higher percentages may reduce contact time slightly but increase risk of surface damage and irritation; 3 % is sufficient.
