A. 3 Sure Benefits of Cleaning the Bathroom with Bleach
When you use it correctly, bleach guarantees these benefits:
1. Disinfects Effectively
Unlike ordinary cleaners, bleach eliminates even viruses like norovirus - giving your family real protection.
2. Eliminates Bad Odors at the Source
Due to humid bathroom conditions, harmful bacteria find it easier to breed in your space. Bleach kills these odor-causing bacteria, mildew, and mold completely. It then replaces that bad smell with its natural odor which actually repels bugs.
3. Brightens and Whitens Your Surfaces
Remember when your bathroom had that shiny, appealing look? Over time it loses that attractive appearance, but you can use bleach to restore the brand-new look of surfaces like your porcelain sink. This will dramatically boost your bathroom's appearance before visitors arrive - check the photo below:
In addition to being hygienic, a clean sink enhances the aesthetics of your bathroom
Although bleach is readily available at home or in shops, many people hesitate to use it properly. All you need to do is learn the correct techniques, and that's exactly what this guide will teach you. But before you rush to pick up that cleaning agent, you must understand these crucial precautions.
B. Precautions When Using Bleach
For the best results and your safety, keep these guidelines in mind:
1. Always Mix Bleach in Well-Ventilated Areas
When diluting concentrated bleach, perform this operation in a well-ventilated space. Ideally, do your mixing in open air. If you must work in your bathroom, open the doors, windows and switch on the exhaust fan. This protects you from becoming dizzy or experiencing breathing problems.

2. Wear Protective Clothing (No Exceptions)
Put on protective gear to shield your skin, eyes, and nose from bleach effects. You must wear:
A. Rubber gloves (protect your hands)

Your hands will be shielded from bleach with these gloves
B. Face masks (prevent inhalation)
You can avoid breathing in bleachy vapors by donning a respiratory mask, like the woman above
C. Long pants (avoid skin contact)

3. Keep Children and Pets Away from Your Work Area
While mixing and cleaning, ensure you keep children and pets far from your workspace. They can easily interfere with your job and face serious safety risks.
4. Never Drain Bleach into Pipes
After cleaning, you might feel tempted to pour remaining chemicals into pipes or septic systems. This will definitely damage your pipes and disrupt your septic system's smooth operation.
5. Never Mix Bleach with Other Chemicals
You might own various cleaning detergents, but you or your family should never mix bleach with other products since this creates dangerous situations. For example, mixing bleach with ammonia produces toxic gas that can seriously harm you.
6. Don't Mix Hot Water with Bleach
When preparing diluted bleach, always use cold water. When you dilute the chemical with hot water, it emits more dangerous fumes that can overwhelm you quickly.
7. Use Diluted Bleach Within 24 Hours
After diluting bleach for cleaning, don't let it sit longer than 24 hours. When you let it sit for extended periods, it decomposes and loses its effectiveness. At the same time, keep undiluted chemicals in cool, shaded areas away from direct sunlight.
C. Do You Know the Dirtiest Part of Your Bathroom?
Your washroom harbors countless germs from walls, toilet, floor, and even curtains. A recent study reveals that your bathroom floor actually has the highest number of germs. This contradicts the popular belief that your toilet seat or bathtub is the dirtiest area. According to a BBC report, your kitchen sponge could be 200,000 times dirtier than your toilet seat!

What you need:

- Turn on your water and let it run until it reaches the hottest possible temperature. Ensure your entire tub fills up (but doesn't overflow) with steaming water.
Hint: If your water doesn't get very hot (about 60°C), boil water in a separate container and add it to your tub.
- Depending on your tub's capacity, add the correct amount of bleach to the hot water. Use the ratio of half a cup of bleach to one gallon of water.
- Allow this solution to soak for about 15 minutes. This gives bleach enough time to work on those deep-seated stains.
- After the required time passes, drain out all water completely.
- By now, your tub should be sparkling clean. If not, mix one part bleach with one part water in a spray bottle. Then spray this solution directly onto stained spots.
- Finally, rinse your entire tub with hot water. Give it a thorough rinse to remove all traces of bleach.

- Allow this setup to rest for half an hour.
- Rinse by flushing out the baking soda and vinegar completely.

Cleaning With Bleach
A. Preparing and sanitizing your toilet's interior
- Measure half a cup of bleach, remove the lid and pour it gently into your toilet bowl. Wipe up any traces of liquid that spill on your floor.
- Take your toilet brush and scrub your toilet's interior. Make sure you clean under the rim, around the waterline and even down the chute thoroughly.
Cleaning the inside of the toilet
- Position your brush under the rim so that clean water can flow through it when you flush.
- Flush your toilet to rinse the brush as well. Shake your brush a little and put it back in its holder.
It's good to start thorough cleaning on a clean surface. Your toilet is now ready for deep cleaning.
B. Cleaning built-up or stubborn stains
Bleach can effectively eliminate stubborn stains from your toilet, but it must be applied and left to work for several hours.
So discuss with your family or roommates to pick the best time for this cleaning project.
Here are the steps for cleaning up built-up or stubborn stains:
- Measure ¼ cup of bleach.
- Carefully lift the lid and pour the bleach gently into the bowl, then return the lid to its position. Close the door and prevent everyone from using the bathroom.
- Let it rest for about ten hours. You can either let it stay overnight or throughout the day.
- After your preset time, open the bathroom door, flush the toilet and lift the lid to check the improvement.
- If you still see traces of stains on your toilet, repeat this procedure. Only this time, let it rest for a longer period than before.

Before spraying your bleach solution, use a mild cleanser to remove urine traces from your toilet completely.
Pay attention to these areas:
- Rim
- Both top and bottom of the seat
- Outer bowl
- Lid: front and back
- Stand
Having cleared urine traces, spray your entire toilet's surface with the bleach solution you prepared earlier.
If you're in a hurry to use the toilet, leave the solution for about a minute, then wipe dry with a clean towel.
Otherwise, for complete sanitization, allow the liquid to dry on your toilet's surface naturally.
I hope your toilet now looks pristine and fresh!

6. Countertops and Sinks
First, begin by cleaning any mess from your sink and countertops.
Next, plug your sink and run hot water into it until it's about halfway full. Measure half a cup of bleach and add it to your sink. Fill it completely with hot water.
Allow your bleach solution to sit in the sink for a few minutes until it returns to room temperature. This provides enough time for odors and bacterial infections to break down.
After putting on your dish gloves, remove the plug and let the water drain out. Fill your sink again with clean cold water and drain again. This removes any traces of bleach that might be lingering on your sink's surface.
Scrub lightly with a sponge or green scouring pad. Just make sure you use scouring materials that are friendly to your sink's surface.
To clean water or soap spots on your sink, pat dry with a dishtowel.
