Why Do This?

It’s not the most pleasant topic, but germs are pretty common around the house. To prevent illnesses and bacteria from spreading to you and your family, it’s important to disinfect liberally. This homemade disinfectant recipe was developed by a food scientist at Virginia Tech to remove salmonella from meat and vegetables, but it also works great for getting rid of cold and flu germs.

Difficulty: Low  Time: 15 minutes

What You'll Need

  • hydrogen peroxide (3% solution)
  • undiluted white vinegar
  • 2 spray nozzles
  • one spray bottle

How to:

  1. Hydrogen peroxide comes in a brown bottle because it’s extremely light sensitive. So leave it in the original bottle! Instead of transferring the liquid to another spray bottle, simply put a nozzle on the brown bottle from the store.
  2. Fill an empty spray bottle with undiluted white vinegar.
  3. Hold your hydrogen peroxide bottle in one hand and vinegar bottle in the other. Mist the surface you’d like to disinfect with the hydrogen peroxide and then follow up with a mist of the vinegar. Important: Don’t combine the two liquids into one bottle – they will form a new chemical if they’re combine that doesn’t work as well.
  4. This technique was developed to be sprayed directly onto food, but you can use it to disinfect anything in your house. (This is especially handy when you have a sick person in your house). If you do use the spray on fruit or vegetables, rinse the food with water after you’ve disinfected to remove any lingering flavors.
