One of the best ways to prepare for a home biohazard cleanup is not to touch anything. Do not remove belongings, even if they are of value or importance, from the area as they are likely contaminated. It’s essential not to use any cleaning products of your own, as the cleaning company will be using chemicals that could interact with your products. 

One thing you can do to prepare is take pictures of your space and belongings that need to be cleaned, especially if you plan on filing a claim with your insurance company. In addition, take time to make a list of items that are valuable, sentimental, or otherwise important. The cleanup company must evaluate these belongings to make sure they are safe. 

Bleach isn’t the best choice to use while cleaning a refrigerator. Food absorbs odors, and bleach is known for its lingering smell, which can then lead to your fresh foods tasting off. Most people don’t safely dilute bleach, either. If you’re concerned about bacteria or mold from contaminated food, the Centers for Disease Control and Prevention recommends using a bleach solution of 1 tablespoon of bleach to 1 gallon of water for sanitizing. Be sure to let the fridge air out for an hour or more afterward to let the fumes dissipate.

Yes, it’s also important to clean off the back of your fridge several times a year. Cleaning the condenser coils, in particular, will help extend the lifespan of your fridge to ensure that it runs efficiently. Cleaning the back of the fridge also allows you to check that all the lines and cords going to your fridge are in good working condition.

Anything that might have been exposed to fumigation chemicals should be washed before use. Wipe down and sanitize surfaces like countertops and tables, and wash all utensils (or take care to store them in an airtight box beforehand), as well as anything else that could find its way into someone’s mouth, like kid or pet toys.
