The short answer
Start with Safety and Drying
Before you disinfect, make sure the power is off in wet areas and that the structure is stable. Wear rubber gloves, boots, and a mask to protect yourself from mold and contaminants. Open windows and doors to increase airflow, and use fans if you have them.
Remove standing water and wet items as quickly as you can. Carpets, padding, and upholstered furniture that soaked up floodwater often need to be thrown out because they are hard to clean fully. Dry out the remaining surfaces with towels and dehumidifiers, as moisture invites mold growth.
Clean Surfaces Before Disinfecting
Disinfectants do not work well on dirty surfaces. First, scrub walls, floors, and countertops with soap and water to remove mud and grime. Rinse with clean water and let the surface dry.
After cleaning, apply a disinfectant solution. A common mix is one cup of unscented household bleach per gallon of water, but always follow the label instructions. For surfaces that touch food, use a food-safe sanitizer. Let the disinfectant sit for the time listed on the label, usually a few minutes.
- Wear gloves and eye protection
- Ventilate the area
- Remove all mud and debris first
- Use a bleach solution or EPA-registered disinfectant
- Allow surfaces to air dry completely
- Dispose of contaminated cleaning materials safely
Handle Soft Items and Personal Belongings
Clothing, bedding, and towels that got wet can often be washed in hot water with detergent and bleach if the fabric allows. Check labels first. Items that cannot be washed, like mattresses or stuffed toys, may need to be discarded if they soaked in floodwater.
Books and important papers can be dried slowly in a well-ventilated area, but they may still need to be thrown away if they are heavily contaminated. For sentimental items, consider consulting a professional conservator. Local water damage pros can help you decide what is worth saving.
Disinfect the Air and HVAC System
After cleaning surfaces, address the air. If your heating or cooling system got wet, do not turn it on until it is inspected. Mold can grow in ducts and spread through the house. A professional can clean and disinfect the HVAC system safely.
Use a dehumidifier to keep indoor humidity below 60 percent, as mold thrives in damp air. Air purifiers with HEPA filters can help remove mold spores from the air. In Caldwell's semi-arid climate with cold winters and hot dry summers, you may be able to dry out the home faster by opening windows during dry spells.
- Turn off HVAC until inspected
- Use a dehumidifier to lower humidity
- Run a HEPA air purifier
- Change air filters afterward
- Check for hidden moisture in walls
Know When to Bring in the Pros
If the flooding was extensive or the water was contaminated, such as sewage or chemicals, disinfecting on your own may not be enough. The pros have the tools and training to handle hazardous situations. They can also check for hidden moisture inside walls and under floors.
For a thorough job, consider services like water damage inspection, structural drying, and dehumidification. These can help prevent long-term mold and rot. If you are in Caldwell, keep the contact info for local pros handy for future storms. Acting quickly is important, as mold can start growing within 24 to 48 hours. Policies vary, and your insurer decides what is covered.
- Extensive flooding or sewage contamination
- Visible mold growth
- Wet drywall or insulation
- Unpleasant odors that persist
- Health symptoms like coughing or headaches

How long should I wait before disinfecting?
You can start disinfecting as soon as the area is safe and you have removed standing water and debris. Do not wait, because mold and bacteria multiply quickly. If the power is off, use battery-powered fans and open windows to dry the area.
Can I use vinegar or hydrogen peroxide instead of bleach?
Vinegar is not a strong disinfectant for floodwater, which can contain harmful germs. Hydrogen peroxide can work on some surfaces, but bleach is more reliable for most hard, non-porous materials. Always follow label instructions and never mix cleaners.
What should I do with items that cannot be cleaned?
Items like mattresses, upholstered furniture, and drywall that soaked in floodwater should be thrown out. They can trap moisture and grow mold. For valuable items, ask a professional restorer for advice. Check your policy and document everything for your insurance claim.
