Tips To Reduce Bacteria And Viruses In Your Home

Germs don’t just lurk in your kitchen and bathroom, but they thrive in the most unexpected places in your home. Here are a few tips to sanitize the house and take care of both the germs that are airborne and stay on the surface. By keeping the house cleaner, you can reduce the pressure on your air purifier and help it last longer.

1. Start with the kitchen sink

While you may think that the trash can or dust bin is the dirtiest and germiest area in the kitchen, a lot of bacteria thrive on the kitchen sink, sponge and scrubber. The biggest source of germs come from the tiny pieces of raw meat and other food particles that stay stuck around the corners in your kitchen sink.

Make sure you clean and disinfect the kitchen sink thoroughly with a good disinfecting antibacterial cleanser. To sanitize the sponge, put a wet sponge in the microwave and run on high heat for 2 minutes to kill any bacteria.

2. Don’t forget the kitchen counter

Simply cleaning the sink may not be enough and you need to also take care of the countertop too. No matter how tired you are after cooking dinner, spare a few minutes to wash the countertop with hot soapy water to remove any grime and gunk that become breeding ground for germs.

Disinfect with a solution made of one cup of bleach mixed in a gallon of water, and let it air dry. Also, remember to clean the cutting board and knife. If the cutting board can develop cracks or ridges, replace it to prevent bacteria from thriving in those cracks.

3. Keep the towels clean

If a towel is used by only one person, wash it weekly and don’t forget to sanitize with hot water and disinfectant if someone is sick. Remember to wash the gym towels after each workout and replace the hand towels frequently or after you have guests in the house. Wash towels in hot water to kill any germs and air dry completely before using it again.

4. Clean the laundry area

Most people live under the illusion that their washing machines are the most sanitized places in the house, but it’s not. A dirty laundry area can add bacteria and viruses in your washer as well as future loads, not to mention the bad odor adding to your woes.

To keep the laundry area clean and sanitized, run an empty washer with a cup of bleach once every week. To keep your clothes germ-free, make sure you run the dryer with wash load at the highest temperature setting that the fabric can sustain.

5. Remove bedroom germs

To get rid of the bedroom germs, make sure you wash the bed linens in hot water at least once weekly, and more frequently if someone is sick. Always clean the soiled items such as the clothes with stains or mud separately from other laundry items, especially the bedsheets. Make sure you keep the snacks and food away from the bedroom as the crumbs attract a lot of bacteria and mold.

6. Sanitize the living room

9 Easy Living Room Organization Hacks

This is an important area of the house where family members come together to watch TV and relax (sometimes with pets cuddling with them). Guests will also spend time in the living area so it gets a lot of outside germs.

Make sure you sanitize every corner of the living room by cleaning spots like coffee tables, telephones, video controllers, TV remotes, and sofa covers. Clean the surfaces with disinfectant wipes, use a damp microfiber cloth to remove dust from TV and wash the sofa covers and rugs once a week. Vacuum clean the carpet and other areas to keep the living room germ-free.

7. Don’t miss the home office

Almost every house, no matter how small will have an office corner with desktop/ laptop, printer, and telephone. These are a breeding ground for bacteria and viruses, especially if you love snacking while you work.

You will be surprised to find the kind of dust and dander within your keyboard. Remember to shake it out often in order to clean and use a vacuum cleaner to suck out the stubborn dust and germs. You may then use a disinfectant wipe to clean and wipe the computer screen using a damp microfiber cloth.

8. Disinfect the railings and knobs

Some of the gunkiest spots in the house are railing handles, doorknobs, light switches, faucets, lamps, and cabinet handles. The germs in hands get transferred to these spots and spread quickly, so don’t forget to sanitize them while cleaning the house.

Use a nice disinfectant or antibacterial cleanser to wipe these spots at least once a week, and clean more often if someone in the house is sick or you have guests.

9. Cleaning the Kids rooms

Kids and germs seem to be inseparable because no matter how much you try, kids love to do all the dirty stuff. While the top air purifier for bacteria and viruses takes care of the airborne hazards, make sure you wipe down the surface with a disinfecting spray.

If you have a small baby in the house, you must disinfect the diaper changing area, plastic toys, slats, and crib rails. Spray a disinfectant on all these spots, leave for about 30 seconds and then wipe down with a wet cloth or paper towel.

10. Take care of the fridge

Besides the airborne germs and other obvious areas, there are several other much-ignored breeding grounds of bacteria and viruses. One such example is the fridge, so we suggest that you disinfect the fridge by cleaning the inside walls, shelves, and doors with hot soapy water once a month.

To get rid of the stinky smell, prepare a mixture of half white vinegar and half water, and clean the interior with it. Alternatively,  you may create a paste of water and baking soda to clean the fridge and then let the interior area air dry before use.

11. Getting rid of germs in bathroom

How to Fix a Bathroom Smelling Like Rotten Eggs?

Germs don’t just thrive on the bathroom floor, but also under the shower, faucet, cabinet, bathtub, towel rings, and so on. To disinfect these areas, create a solution by mixing two tablespoons of a liquid dishwasher, two tablespoons of ammonia, and one part of warm water. Rinse with water

You may also use a paste of baking soda and water to get rid of the stubborn stains and ugly hard watermarks in the tub or sink. Always use a squeegee to remove water from the wall tiles to prevent hard watermarks from forming.

12. Tackle the toilet germs effectively

Always remember to put the lid of the toilet down when you flush in order to prevent the germs from spreading all over the bathroom. Clean the toilet bowl weekly and always keep the lid down. You must also use a damp cloth and an all-purpose bathroom cleaner to disinfect the seat, lids, and bowl area.

If you don’t prefer using chemical-based toilet cleaners, consider using diluted bleach which works best for disinfecting against bacteria and viruses. Use a mixture with one part of white distilled vinegar and nine parts of water in a spray bottle to clean the surface and degrease.

13. Sanitize the carpets and hallways

When you or guests walk into the house wearing shoes, it’s an open invitation to bacteria, viruses and other germs. To save your carpets, rugs, and floors, keep the shoes at the door. If you must wear shoes inside, keep a rug at the door to clean shoes before walking in.

Vacuum clean the carpets and rugs once a week and mop the floors with a disinfectant cleanser once to twice a week as needed.  Don’t forget to vacuum clean the top shelves, under the bed, ceiling fans, and other hard to access areas.
