Cleaning Facts About Germs
Let’s get into some interesting germ facts. We’ll talk about where germs fester, how to tackle them, and some great cleaning tips that can help combat germs, viruses, and bacteria.
- Wash your hands: The most cost-effective way to reduce germs is by washing your hands (1). You can do all the cleaning and scrubbing of your home, but if you don’t wash your hands regularly, you’re more likely to get ill. In fact, the CDC put out a statement that one million deaths per year could be prevented by routine handwashing. If you work in an office or hospital, you should do this regularly because these are dirty places!
- Germs multiply: One germ can multiply into over eight million germs in just 24 hours. A significant way to prevent this is by routine hand washing and disinfecting your electronics, including your phone, remote control, and keyboard.
- When to wash: When cleaning around the house, there are critical times to clean your area and hands. You should always clean your hands and the surface you’re working on before, during, and after preparing food. Always wash your hands before eating. Wash your hands after using the toilet or changing diapers, as well as the area around you. Wash your hands before and after handling pet food. And always wash your hands after taking out the trash.
- Regularly clean common surfaces: Think about the surfaces used the most, such as the kitchen countertops or the bathroom sink. Clean these frequently to prevent the spread of germs.
- Germs in the washing machine: You might think your washing machine is clean since it’s in contact with detergent and warm water most days. But it’s actually full of dirt and germs from dirty laundry, so it’s necessary to deep clean the inside and outside of the washing machine every month.
- Wash your towels: Germs love to live in towels because they’re moist and warm. You should wash your own towel once a week and avoid sharing towels. Wash gym towels after each use. Try to wash kitchen towels separately from bathroom towels.
- Germs in the bedroom: No, we’re not talking about cooties. We’re talking about real hazardous germs and even mites. Wash your bed sheets every week to minimize germs. Keep food out of the bedroom as this can easily attract bacteria.
- Clean knobs and railings: As you know, you transfer germs via your hands, so cleaning the things we touch most is essential. Once a week, disinfect your doorknobs, handles, railings, faucets, lamps, light switches, and other things you brush past daily.
- Clean your kids’ toys: Your little one plays with toys regularly and even puts them in their mouth at times. Once a week, if you have time, disinfect your little one’s things to prevent illness.
- Ditch the kitchen sponge: Did you know your kitchen sponge has been found to host 362 different species of bacteria, with 45 billion per square centimeter? To minimize this, replace your sponge every couple of weeks and clean it every few days by wetting it and putting it in the microwave for a minute. You should also keep the sponge away from raw meat.
- Germs spray around when you flush the toilet: When you flush a toilet with the lid up, you can spread germs as they hang out in the air. In fact, some tests show that tens of thousands of droplets spread for each flush. This can spread harmful diseases such as Ebola and norovirus. Lower the lid down, then flush.
- Your kitchen is full of germs: The National Sanitation Foundation found that the kitchen has more bacteria and fecal contamination (yuck!) than other areas of the home (2). The dirtiest places are the fridge, kitchen sink, countertops, cutting boards, and coffee maker.
Residential Cleaning Statistics
Let’s dig deeper into some of the facts about cleaning habits in the home. Do you relate to any of these? Maybe we can all learn a new hack!
- We spent hours cleaning: On average, Americans spend around six hours a week cleaning their home. We’re not being funny. That’s like a whole other day of work! Only 10 percent of people clean their homes for less than an hour per week. Thirty-one percent wonder if they are cleaning their homes properly.
- Least favorite cleaning tasks: The study found that the most hated cleaning task is the bathroom. Fifty-two percent of people dread that the most, with 23 percent dreading the kitchen the most. Next up is dusting, then mopping, then laundry.
- Make priorities: If you’re only going to do a couple of cleaning tasks in each room, here’s what you should prioritize. In the bathroom, disinfect the toilet bowl, sink, tub, and shower. In the kitchen, clean the cutting boards, countertops, and dishes. In the laundry room, wash your sheets, towels, and bathmats weekly. Vacuum carpets and mop floors weekly.
- Minimize mess and germs: The best way to keep your home clean is by avoiding clutter, washing your hands regularly, and removing shoes at the door. Keep your bathroom and kitchen surfaces clean and dry, clean up food immediately, and treat stains ASAP.
- Who does more housework?: Studies have found that 59 percent of women claim to do more household chores than their male partners. Only six percent of women say their male partner does more housework. Meanwhile, 46 percent of men say that the housework is split equally.
- Chores cause arguments: One poll found that a third of people would have broken up a relationship over household chores. Sixty-seven percent of people admitted that they argued with their partner or housemates about cleaning tasks on average three times per week. The most common grievances include leaving the toilet seat up, leaving drawers or cupboards open, and forgetting to close the fridge door.
- A clean home improves mental health: If you wanted a great reason to clean your home this evening, this could be it. It’s proven that a clean home actually improves mental health, focus, and productivity.
- Less time to clean: More 30-50-year-olds are hiring cleaning services for their home. Since we are all working more, we have less time with our family every week. Hiring a cleaner allows many people to spend their free time doing fun things rather than chores.
- The cleanest and dirtiest states: A study found that the states with the cleanest homes were the District of Columbia, Tennessee, and Mississippi. The states with the dirtiest homes were Oregon, Alaska, and New York. This tends to line up with the states with busier lifestyles, leaving people with less time to clean their homes. This study also found that people between 35 and 44 have messier and dirtier homes, whereas people above 55 have much cleaner homes.
- These cleaning mistakes are unattractive: The above study found some of the biggest cleaning dealbreakers in a romantic relationship. This included leaving dirty dishes out, never offering to help clean, wearing stained clothes, and leaving dirty clothes on the floor.
- Spring cleaning facts: While you shouldn’t save your deep cleaning for springtime, 77 percent of households do a spring clean every year. On average, this takes about six days to do. The top priorities for this week-long cleaning spree are cleaning windows, closets and drawers, ceiling fans, blinds, curtains, and carpets. As a result, people said they felt accomplished, satisfied, safe, and happy after spring cleaning.
- Get into the habit: You should clean your sheets every week. You should disinfect your sinks every day. Vacuum rugs and wash floors every week or two. Clean the bathroom weekly, at least. These are some helpful household habits to get into.
Hotel Housekeeping Fun Facts
When you go to a hotel, you expect it to be clean and fresh. Sometimes it is astoundingly hygienic, and other times, it’s a bit disappointing. Let’s look at some hotel housekeeping facts that may or may not surprise you.
- It doesn’t take too long: On average, it only takes around 31.5 minutes for hotel housekeepers to deep clean the room between guests. It takes 20.5 minutes for housekeepers to clean the room if the guest is staying another night.
- One hundred checkpoints per room: Many hotels have 100 checkpoints a housekeeper must do before a new guest arrives. This includes changing the beds, vacuuming, and ensuring the TV is set to the correct guide before the guest arrives.
- Average pay: The average hotel housekeeper is paid $13.79 per hour. The top paying hotels include IHG Hotels & Resorts at $30.46 per hour, Wyndham Hotels & Resorts at $25.56 per hour, and The Williamsburg Hotel at $20.62 per hour.
- Which states pay the most?: Chicago is the highest paying city for hotel housekeepers in the US, paying $17.52 per hour on average. New York is next at $16.99 per hour, and Orlando is one of the lowest, paying $12.88 per hour on average.
- Housekeepers aren’t very satisfied: Based on Indeed’s survey of over 1,600 hotel housekeepers, only 36 percent are satisfied with their salary. Housekeeping is very time-consuming and laborious, so it makes sense that they want to earn more.
- Housekeeping can lead to injury: Many studies found that housekeeping is a dangerous job within the hotel (3). These workers are dealing with heavy mattresses, climbing into high places and on their knees often to scrub floors. Seventy-seven percent of hotel housekeepers said their workplace pain affected other routine activities. Sixty-six percent had to visit a doctor for help with work-related pain.
- You can tip your housekeeper: If you want to leave your housekeeper a tip, leave money out with a note or pop some cash underneath your pillow.
- Housekeeping is a high expense for hotels to cover: One of the highest costs for a hotel is housekeeping. Hotel housekeepers must do an excellent job in mere minutes to ensure every room is ready for the guests.
- Not everything will be 100 percent clean: While housekeepers do a brilliant job, some things aren’t always tackled. For instance, there might still be bed bugs since they are almost impossible to see to the naked eye. Hotel whirlpools will also be full of bacteria. So if you’re going to a hotel, keep these gross facts in mind and wash your hands often.
- Blankets aren’t always washed: While the bed linen is washed between guests, bed throws aren’t laundered as often as you’d like. If you see a blanket on the bed, you may want to avoid curling up inside it.
- What do housekeepers do?: Between guests, they will replace towels and linen and restock toiletries, tissues, and toilet paper. They also replace drinking glasses, disinfect the bathroom, polish and dust furniture, empty the trash, vacuum floors, and wash uncarpeted areas. That’s not all: replacing light bulbs, emptying ashtrays, cleaning hallways and washing windows are also on their list.
- It can be a lonely job: Most hotel housekeepers work on their own. While some might enjoy the solo routine, others liven things up by competing with their colleagues, fighting for better trolleys or nicer rooms.
Cleaning Trivia Questions
Let’s finish off with some fun trivia questions you may be wondering. You never know, these might come in handy at your next pub quiz.
- Should you dust before or after cleaning the floors? Always dust before. When you dust, that dust lands on the floors and furniture. When you vacuum, you then pick up the dropped dust.
- How many calories does cleaning burn? Cleaning can burn between 80 and 400 calories per hour, depending on the cleaning task. So if you’re deep cleaning, you can skip your workout that day!
- What is the dirtiest part of a home? The kitchen sponge.
- Is indoor or outdoor air quality better? Air in our homes can be more polluted than outdoor air, even in big cities. This can be altered by using more eco and non-toxic cleaning products.

- How can you minimize allergic reactions while vacuuming? If the dust is getting to you while you vacuum, you need to get one with a true HEPA filter. This will capture over 99 percent of dust and allergens so that you can breathe easier.
