Hey Clean Freaks!
Let me ask you something.
Have you ever spent an entire afternoon cleaning your house, stepped back to admire your work, and thought…"This place looks amazing."
Floors are vacuumed. Counters are spotless. Bathrooms smell like lemon cleaner.
You sit down on the couch feeling proud of your cleaning victory. Then someone grabs the remote control with greasy pizza fingers. Suddenly that spotless home does not feel quite as spotless anymore. However, many people don’t realize - the dirtiest places in your home are usually the ones people never think to clean.
Today I want to share a few of the biggest hidden germ hotspots I see all the time. Once you start cleaning these areas regularly, your home will feel next level clean.
Let’s Go! 👇
🚪 1. Light Switches and Door Handles
If germs had a favorite vacation spot in your house, light switches and door handles would be on the top of the list.
Think about how many times these get touched every day.
Kids running through the house.
Guests coming over.
You are turning lights on and off all day long.
All those hands leave behind oils and bacteria. And yet most people clean around them instead of cleaning them.
In my early years working as a janitor, I learned a lesson that stuck with me. My Grandma told me, “If you want to stop germs from spreading, clean the things people touch.” That advice completely changed how I approached cleaning. I started paying attention to high touch surfaces. Light switches. Door handles. Cabinet pulls. Refrigerator handles. And what I found was eye opening.
Cleaning these areas is simple. A disinfecting wipe or microfiber towel with a mild disinfectant works perfectly. I recommend wiping down switches and handles during your regular weekly cleaning routine.
Pro Tip: Wipe them down once a week. It takes about two minutes.
📺 2. Remote Controls
This might be the germiest thing in your living room. Why? Because they combine three things germs love. Constant handling, food residue, and almost zero cleaning. Think about how people typically use a remote control. You're sitting on the couch watching a movie. Maybe you're eating popcorn, pizza, or snacks. Your hands might be a little greasy or covered in crumbs. And without thinking, you grab the remote to change the volume. All of it ends up between those buttons.
At home, remote controls should be wiped down regularly. A disinfecting wipe works well, but I also like using a microfiber towel slightly dampened with rubbing alcohol. It cuts through oils and evaporates quickly without damaging the electronics. And if you want to go the extra mile, use a soft brush or toothpick to remove debris between the buttons.
A quick wipe makes a huge difference!
🧽 3. Kitchen Sponges
This one shocks people.
Most people assume the toilet is the dirtiest thing in the house. But numerous studies have shown that kitchen sponges can contain millions of bacteria, often far more than a toilet seat. Why does this happen? This is because sponges provide everything bacteria need to thrive.
Moisture.
Food particles.
Warm temperatures.
Every time you wipe down a countertop or wash a dish, tiny bits of food get trapped in the sponge. Then the sponge stays damp in the sink, giving bacteria the perfect environment to multiply.
It stays wet.
It collects food particles.
It rarely gets replaced.
In fact, researchers have found over 350 different types of bacteria living inside typical kitchen sponges. One of the easiest ways to improve kitchen hygiene is cleaning your sponge regularly and/or simply replacing.
Interesting Info from the USDA: According to the USDA Microwaving sponges killed 99.99999 percent of bacteria present on them, while dishwashing killed 99.9998 percent of bacteria. Thus microwave heating and dishwashing with a drying cycle proved to be the most effective methods for inactivating bacteria, yeasts and molds on sponges.
How to Microwave a Sponge Safely?
🚨 USE EXTREME CAUTION
No Metal!: Inspect the sponge for any metal particles or metallic scrubbing pads (like steel wool). Never microwave a sponge with metal, as it will cause sparks and potentially a fire.
Saturate with Water: The sponge must be dripping wet. A dry sponge is a fire hazard and can quickly melt or ignite in the microwave.
Microwave on High: Place the wet sponge in a microwave-safe bowl. Heat it on high for 1 to 2 minutes. One minute is usually sufficient to kill most bacteria.
Cool Down: The sponge and the steam it produces will be very hot. Use tongs to remove it, or let it sit in the microwave for at least 10–15 minutes to cool before handling.
How to Clean a Sponge in your Dishwasher?
Simply place the sponge in the dishwasher. Make certain you select a HOT drying cycle. Adding the HOT drying cycle proved to be one most effective methods to drastically reduce bacteria
🪥 4. Toothbrush Holders
Your toothbrush holder might look harmless, but it is one of the most overlooked germ hotspots in the bathroom. Think about what happens every morning and night. You brush your teeth. You rinse the toothbrush. Then you place it back into the holder.
Over time, water drips down the handle and collects in the bottom of the holder. That standing moisture mixes with toothpaste residue, bacteria from your mouth, and bathroom humidity.
Before long, the bottom of the holder becomes a breeding ground for bacteria and mold. In fact, studies have found that toothbrush holders are often one of the germiest items in the bathroom, even more contaminated than toilet seats.
Cleaning your toothbrush holder is quick and easy. Once a week, simply remove it, empty any standing water, and wash it with hot soapy water. Alternatively, you can use a Denture Tablet! (Read more about this method on our blog) If it is dishwasher safe, running it through the dishwasher occasionally works even better.
It is one of those tiny tasks that can take less than a minute but dramatically reduces germs.
🧺 5. Washing Machines
This one also surprises a lot of people. Your washing machine! After all, it cleans things. How dirty could it really be?
The answer is… surprisingly dirty if it is not maintained.
Modern washing machines operate with lower water levels and cooler temperatures than older models. While this is great for saving energy, it also means soap residue, fabric softener, body oils, and detergent buildup can accumulate inside the machine.
Front loading washers in particular are known for developing mold and mildew around the rubber door gasket. To keep your washing machine clean, run an empty hot cycle once a month with washing machine tablets or white vinegar.
Also wipe down the rubber gasket, detergent drawer, and door seal. If you have a front loading washer, leave the door slightly open after washing so moisture can dry out. A clean washing machine means cleaner laundry.
The Clean Takeaway
Cleaning a home is a little like painting a picture. The big strokes matter. Vacuuming the floors. Wiping the counters. Scrubbing the bathroom. But the small details are what truly make the difference.
By paying attention to hidden germ hotspots like light switches, remote controls, kitchen sponges, toothbrush holders, and washing machines, you eliminate the places where bacteria quietly build up over time.
These are the little details that elevate a home from “looks clean” to feels truly clean. The best part? Most of these tasks take only a few minutes. If you want the cleaning tools that make these jobs fast and easy, check out the Clean That Up Amazon Store.
I have put together a collection of my favorite cleaning tools that I personally use and recommend. Because the right tools can make cleaning a whole lot easier.
The next time you clean your home, take a moment to look beyond the obvious surfaces. Wipe down the things people touch. Replace that old sponge. Give your washing machine a quick refresh.
Your home will be cleaner, healthier, and far more hygienic because of it. ✨
