During the COVID-19 pandemic, many families are staying home. Our team of environmental pediatricians has put together some information to help keep your indoor environment safe and healthy.
Preventing the Spread of Germs in Your Home:
Safe Disinfecting and Good Hand Washing
Cleaning, sanitizing, or disinfecting: what do they mean?
- Cleaning: removes germs, dirt, and grime from household surfaces. Cleaning does not kill germs, but removes some of them.
- Sanitizing: lowers the number of germs on a surface to a level deemed safe by public health organizations. This can include either cleaning or disinfecting.
- Disinfecting: kills germs on surfaces after a surface is cleaned by using a disinfecting cleaning product.
When is disinfection needed?
- All households should routinely clean and disinfect “high-touch” surfaces like doorknobs, light switches, and faucets.
- For households with confirmed or possible COVID-19 cases, more extensive disinfection and additional precautions are needed.
How can I safely disinfect my home from coronavirus?
- Chemical disinfectants like hydrogen peroxide, diluted bleach, or another EPA-certified disinfectant are important to control germs such as the coronavirus.
- Disinfectants must be used correctly, safely, and according to manufacturer’s instructions to avoid harm to health. Open windows for fresh air. Keep children out of the area- children with asthma are especially sensitive to bleach and other strong chemicals.
- Remember to securely store all cleaning products (and other chemicals) out of the reach of children.
What products are available to disinfect my home?
- Selecting hydrogen peroxide: Over-the-counter hydrogen peroxide (3%) can be used for general household cleaning.
- Use it safely: Pour a small amount of peroxide solution into a spray bottle, and apply carefully to surfaces. Let sit for at least 6 minutes. After, wipe off with a cleaning towel. Store-bought cleaners with hydrogen peroxide as the active ingredient should be used as directed on the bottle.
- Store it properly: Hydrogen peroxide loses its strength quickly when exposed to air or sunlight. After opening, keep the unused peroxide in its original bottle and seal tightly
- NEVER mix bleach and ammonia or any other cleanser – this can create toxic fumes.
- Safety: Wear gloves. Open windows for fresh air. Keep children out of the area. Children with asthma may be particularly sensitive to bleach and other strong odors.
- Selecting bleach: Common household or laundry bleach (5.25% or 6%) bleach should be used. Do not use industrial strength bleach.
- Dilute it carefully: Use a funnel to carefully dilute the bleach with cool water. Always ensure to make a fresh batch as it can lose its strength overtime.
- Before disinfecting with bleach: clean surfaces with soap + water, then wipe dry.
- Apply diluted bleach safely: disinfect by carefully applying to the surface until glistening wet. If using a spray bottle, make sure it is on the “stream” setting (avoid using “mist” settings).
- Disinfecting time: Allow surfaces to completely dry (or wipe down with a paper towel after letting it sit for 5 to 10 minutes).
- While Clorox wipes are a fast and convenient tool for cleaning that are generally safe, they can pose risks to certain populations, so use them safely!
- Safety: Open windows for fresh air. Gloves are generally unnecessary, unless you are using hospital-strength wipes. Keep children out of the area. Children with asthma may be particularly sensitive to bleach and other strong odors.
- Not all Clorox wipes are created equal: Take note of the strength of the product you are purchasing. There is no need to use hospital-strength wipes in the home, and doing so may actually be harmful for families (these products are commonly labeled as “hospital-grade,” “healthcare-grade,” or “ultra”).
- Where to use wipes: Wipes work best on solid surfaces; look to other methods of cleaning for fabrics or other materials.While many wipes are safe to use in kitchens, they should not come in direct contact with food or utensils.
- Use it correctly: Wipe the surface to be disinfected, ensuring enough product is applied to give the surface a wet appearance. Let it dry. Check the label and follow recommendations for the amount of time you should let it sit before touching or using.
- An undiluted isopropyl alcohol solution (at least 70% strength) can be used as disinfectant. These can be found over the counter.
- Safety: Open windows for fresh air. Keep children out of the area. Children with asthma may be particularly sensitive to bleach and other strong odors. Store safely, out of the reach of children. Make sure to keep away flame, heat or sparks when using.
- Where to use wipes: Isopropyl alcohol is most effective on hard surfaces.
- Use it correctly: Prep the surface by cleaning it with water and detergent. Apply the isopropyl alcohol and let sit for at least 30 seconds.
- Can alcohol-based hand sanitizer be used as a household disinfectant? Hand sanitizers are not meant to be used for disinfecting. If possible, stick to products specifically designed for disinfecting surfaces in your home.

Frequent hand washing with soap and warm water is the most effective method of reducing transmission of coronavirus. What are the safer options for hand washing?
- Regular soap and water will work well to prevent the spread of germs. Remember to rub and scrub all hand surfaces for at least 20 seconds.
- If soap and water are not available, use an alcohol-based sanitizer to kill germs. This should be used safely and stored out of the reach of children.
- The CDC recommends products with at least 60% ethanol or 70% isopropyl alcohol. Do not attempt to make your own hand sanitizer at home- it can be harmful if not made correctly or it may be ineffective (unable to kill coronavirus).
- First, ensure that hands are not greasy or dirty. If they are, wash with soap and warm water (if available).
- Apply hand sanitizer to the palm of one hand and rub it on both hands and between fingers until dry. Use enough to cover all sides of both hands.
- Frequent hand washing can lead to dry hands. If needed, use a fragrance-free lotion.

My child has asthma and is now spending most of their time inside my home. How can I reduce common asthma triggers in my home safely and effectively?
Keep Pests Out: Pests like cockroaches and mice are common and can trigger allergies and asthma. Using safe methods to prevent and get rid of pests are important. Eliminating the use of chemical pesticides is one important step.- Rx for Prevention: Pests and Pesticides (español)
Don’t Smoke: Smoke from the end of a burning cigarette, cigar, or pipe contains a mixture of chemicals that can make asthma worse. These chemicals can persist in the environment and remain on surfaces, clothing, and skin. Rx for Prevention: Secondhand Smoke (español)
Use Cleaning Products Safely: Whether you need to do routine cleaning to remove dust and grime, or disinfect high-touch surfaces to kill coronavirus (and other germs), use safer products and practices! Remember to keep all cleaning products safely stored. When cleaning, keep kids out of the area, open the windows to ventilate with fresh air, and follow product instructions closely.
