When you think of dirty items in your house, your mind might immediately jump to the bathroom or bins. However, some of the dirtiest items in your house are hiding in plain sight.

Here’s a list of everyday items that might be harboring more germs than you think and tips on how to clean them.


The dirtiest items in a house


Kitchen Sponge 

Your kitchen sponge is a breeding ground for bacteria. A study found it can contain more bacteria than a toilet seat! To clean it run it through the dishwasher.


Dish Towels 

Dish towels often come into contact with raw food, dirty hands, and wet surfaces, making them a hotbed for germs. Wash them frequently on a hot cycle.


Smartphones and Tablets 

We take our devices everywhere, including the bathroom. Studies show they can carry more germs than a toilet handle. Wipe them down daily with a microfiber cloth and a disinfectant safe for electronics.


Remote Controls 

Remotes get touched by everyone in the household, often while eating or lounging. Clean them regularly with disinfectant wipes.


Light Switches and Door Handles 

These high-touch surfaces can accumulate germs quickly. Wipe them down with a disinfectant weekly, or more often if someone is ill.


Toothbrush Holder 

The bathroom is a humid environment, and your toothbrush holder is often exposed to bacteria from the air and your toothbrush. Clean it in the dishwasher or by hand with hot, soapy water.


Pillows and Pillowcases

Pillows can harbor dead skin cells, sweat, and dust mites. Wash pillowcases weekly and pillows every few months.


Cutting Boards 

Whether they’re used for meat, veggies, or bread, cutting boards can be a home for bacteria. Clean them thoroughly with hot soapy water and also sanitise them.


Laundry Baskets 

Laundry baskets hold dirty clothes, which can contain bacteria and germs. Wipe them down with disinfectant or wash fabric liners regularly.


Pet Toys and Bowls 

If you have pets, their toys and bowls can also harbor bacteria. Clean bowls daily and wash toys regularly.


While it’s impossible to eliminate all germs, regular domestic cleaning and disinfecting of these often-overlooked items can help keep your home healthier. Pay attention to high touch and damp environments, and incorporate simple cleaning routines to reduce germs in your living space.


Frequently Asked Questions: The Dirtiest Items in Your House and How to Keep Them Clean


What are the dirtiest items in your house that need cleaning regularly?

Some of the dirtiest items in your home are everyday objects that are touched frequently but often overlooked. Kitchen sponges, dish towels, remote controls, smartphones, light switches, door handles, toothbrush holders, and cutting boards can collect large amounts of bacteria and germs. Regular cleaning and disinfecting of these high touch areas can help create a healthier home environment.


How often should I clean the dirtiest items in my house?

The cleaning frequency depends on how often an item is used. High touch surfaces such as door handles, light switches, phones, and remote controls should ideally be cleaned weekly, or more often during illness. Items like kitchen sponges, dish towels, pet bowls, and cutting boards require more frequent cleaning because they can quickly collect bacteria from food, moisture, and daily use.


What is the dirtiest item in a kitchen and how do I clean it?

A kitchen sponge is often considered one of the dirtiest items in a home because it stays damp and collects food particles, creating the perfect environment for bacteria to grow. Replace sponges regularly and clean reusable ones by washing them thoroughly or placing them in the dishwasher if suitable. Kitchen cloths and dish towels should also be washed frequently on a hot cycle.


Why are remote controls one of the germiest items in a house?

Remote controls are frequently handled by multiple people and are often touched while eating, relaxing, or after touching other surfaces. Many people rarely clean them, allowing bacteria and dirt to build up. Wipe your remote control weekly using a disinfectant wipe or slightly damp cloth, paying attention to the buttons and gaps.

  • Fridge handles

  • Computer keyboards

  • Reusable shopping bags


Adding these areas to your regular cleaning checklist can significantly reduce the amount of bacteria around your home.

Keeping a healthier home does not mean eliminating every germ. A good cleaning routine should focus on removing dirt, bacteria, and allergens from frequently touched surfaces. Regularhoovering, disinfecting those high touch areas, washing fabrics, cleaning kitchens and bathrooms, and maintaining good ventilation all help reduce germs inside your home.


How often should I have a deep clean to remove hidden dirt and germs?

A professional deep cleaning service can target areas that are not usually included in a standard clean, such as behind furniture, skirting boards, kitchen appliances, door frames, and other hidden areas where dust and bacteria can accumulate.

  • Door handles

  • Light switches

  • Phones and tablets

  • Remote controls

  • Computer keyboards

  • Stair rails


Regularly disinfecting these areas helps prevent the spread of germs throughout your household.
