The Dirtiest Items in Your Home That You Probably Aren’t Cleaning

You may think your home is spotless, but some of the dirtiest items in your house are the ones you rarely clean. While counters, floors, and bathrooms get regular attention, everyday objects harboring bacteria and germs, often go unnoticed. These overlooked items can spread illness, collect allergens, and impact your home’s overall cleanliness. Let’s uncover the dirtiest items in your home and how to clean them effectively.


1. Remote Controls – A Hidden Germ Hotspot

Remote controls are touched multiple times a day by different people, yet they are rarely cleaned. Studies have shown that remotes can harbor bacteria, viruses, and even mold.

How to Clean It:

  • Remove the batteries before cleaning.
  • Use a disinfectant wipe or a microfiber cloth with rubbing alcohol to wipe down all buttons and surfaces.
  • Use a toothpick or cotton swab to clean between buttons.
  • Clean remotes at least once a week to reduce germ buildup.

2. Light Switches – The Most Overlooked High-Touch Surface

Every time you turn on a light, you transfer dirt and bacteria onto the switch. Since light switches are often overlooked, they can become a breeding ground for germs in homes.

How to Clean It:

  • Use a disinfecting wipe or a cloth dampened with rubbing alcohol.
  • Pay extra attention to frequently used switches, such as those in kitchens, bathrooms, and entryways.
  • Clean switches at least once a week to prevent germ buildup.

3. Kitchen Sponges – The Dirtiest Item in Your Home

Your kitchen sponge absorbs bacteria from food particles and moisture, making it one of the dirtiest items in your home. It can even spread bacteria to your dishes and countertops.

How to Clean It:

  • Microwave a damp sponge for one minute to kill bacteria.
  • Soak it in a mixture of hot water and vinegar for deep sanitization.
  • Replace sponges every 1-2 weeks to prevent bacteria buildup.

4. Toothbrush Holders – A Moisture-Loving Bacteria Breeding Ground

Toothbrush holders often collect water residue, which creates the perfect environment for mold and bacteria to thrive.

How to Clean It:

  • Wash the holder with warm, soapy water every few days.
  • Use an antibacterial cleaner or a vinegar solution to disinfect.
  • Allow toothbrushes to dry completely before placing them back in the holder.

5. Cell Phones – Dirtier Than a Toilet Seat

Your phone goes everywhere with you—including places full of germs. Studies have found that the average smartphone has 10 times more bacteria than a toilet seat!

How to Clean It:

  • Use a microfiber cloth with rubbing alcohol or a disinfecting wipe.
  • Pay extra attention to buttons, speakers, and the back of the phone.
  • Clean your phone at least once a day to prevent the spread of germs.

6. Door Handles – A High-Touch Bacteria Zone | Germs in Homes

Everyone in the household touches door handles daily, but they rarely get disinfected. Bacteria and viruses can linger on these surfaces for hours or even days.

How to Clean It:

  • Wipe handles with a disinfecting wipe or an alcohol-based cleaner.
  • Clean handles at least twice a week, and more often during cold and flu season.

7. Reusable Grocery Bags – A Hidden Source of Germs in Homes

Reusable bags are great for the environment, but they can harbor bacteria from groceries, including raw meat and produce.

How to Clean It:

  • Wash cloth or fabric bags in the washing machine weekly.
  • Wipe down plastic or insulated bags with disinfectant after each use.
  • Store bags in a clean, dry place instead of on the floor of your car.

8. Pillows – A Dust Mite Haven

Your pillow absorbs sweat, oils, and dead skin cells, making it a prime location for dust mites and bacteria.

How to Clean It:

  • Wash pillows every 3-6 months in hot water.
  • Use pillow protectors to reduce allergen buildup.
  • Replace pillows every 1-2 years for the best hygiene.

9. Car Steering Wheel – A Germ Hotspot You Touch Daily

Most people clean the inside of their car, but they forget about one of the most-touched surfaces—the steering wheel.

How to Clean It:

  • Use a disinfecting wipe or a damp microfiber cloth with soap and water.
  • Wipe down at least once a week to prevent bacteria buildup.

10. Washing Machine – The Place That Cleans Your Clothes, But Needs Cleaning Itself

Over time, washing machines collect detergent residue, mold, and bacteria, which can transfer onto clothes.

How to Clean It:

  • Run an empty cycle with hot water and vinegar once a month.
  • Wipe down the rubber seal and detergent drawer to prevent mold.
  • Leave the door open after each use to allow air circulation.

Why Professional Cleaning Can Help

  • Disinfect high-touch areas with industrial-strength cleaners.
