2018 Wisconsin Flooding Resources

Cleaning and Sanitizing with Bleach After a Flood

To clean household surfaces with visible mold growth:

  • Mix 1 cup of household bleach with 1 gallon of water.
  • Wash surfaces with bleach mixture. Scrub rough surfaces with a stiff brush.
  • Allow to air dry.

To clean and sanitize household surfaces without visible mold growth:

  • Clean surfaces with a detergent (e.g., dish or laundry) and warm, clean water.
  • Rinse with clean water.
  • Sanitize using a mixture of 1 cup of household bleach with 5 gallons of water. Wash surfaces with mixture.
  • Allow to air dry.

Always be cautious when using bleach by using proper personal protective equipment (mask, goggles, and gloves). Never mix ammonia or acids with bleach.

These resources are intended to help Wisconsin residents and professionals understand the impact mold exposure can have on health, how to prevent mold growth, and how to fix indoor mold problems. Mold spores are constantly traveling through the air all around us and can be found both indoors and outdoors. It is not practical to expect a building or home be completely free of mold; however, indoor mold growth can be prevented and controlled.
