CLEANING AND SANITIZING WITH BLEACH AFTER AN EMERGENCY

Cleaning and sanitizing your household after an emergency is important to help prevent the spread of illness and disease.

Using Cleaning & Sanitizing Products

First, wash surfaces with soap and warm, clean water to remove dirt and debris. Next, sanitize surfaces with household bleach.

It is critical to read and follow the safety instructions on any product you use. Below are the most important safety guidelines when using sanitizing products:

  • Never mix bleach with ammonia or any other cleaner.
  • Wear rubber or other non-porous boots, gloves, and eye protection.
  • Try not to breathe in product fumes. If using products indoors, open windows and doors to allow fresh air to enter.

Cleaning & Sanitizing with Bleach

Use regular unscented 5%—6% household bleach and follow the instructions in the chart below.
