How to disinfect with bleach



So you have a moldy or super dirty surface that you want to clean. No problem. You can just reach for the handy bleach container and clean it up, right? Not so fast! While bleach can be a very effective cleaning and disinfecting solution, it is also a really potent and potentially dangerous chemical. Do not worry. As long as you follow the proper safety precautions, such as making sure to dilute bleach first, you can use bleach to disinfect and disinfect various surfaces.

[[[[Edit]Step

[[[[Edit]Use bleach safely

  1. Open windows to increase ventilation. When diluting or using bleach, always work in a well-ventilated area to avoid inhaling the toxic fumes. Open some windows to increase the air circulation in the room before using the bleach.[1]

    • You can also put on some fans in the room.
    • Another option is to dilute the bleach outside so that you do not inhale the fumes from the concentrated bleach.
  2. Wear rubber gloves and eye protection. Bleach is very corrosive, which means it can burn your skin and your eyes. Always wear a pair of rubber gloves to protect your hands when using bleach. Also, wear goggles or goggles to protect your eyes from bleach entering them.[2]

    • You can also wear trousers and a long-sleeved shirt. Bleach can damage and discolor clothing, so make sure you wear something you do not mind getting stained.
  3. Avoid mixing bleach with other household chemicals. Never mix bleach with other cleaning solutions. Combining bleach with common household chemicals such as ammonia can produce chloramine gas, which is highly toxic and can be life-threatening if inhaled. The only thing you should mix bleach with is water to dilute it.[3]

    • If you accidentally mix bleach with another chemical, leave the area and go out into the fresh air immediately.
  4. Store bleach in a cool, shaded, out of reach. Bleach has an expiration date and becomes much less effective when it expires. It can also be less effective if exposed to sunlight and heat, so keep it slightly cool and dark as a storage cupboard. Place the bleach somewhere high or out of the reach of children.[4]

    • Make sure that the lid is also tight.
    • Once the bleach has run out, discard it and use fresh bleach to disinfect. Check the expiration date on the bottle.

[[[[Edit]Clean a surface with bleach

  1. Choose regular bleach-free 5% -6% bleach to disinfect and disinfect. Household bleach can come in a variety of concentrations and fragrances. Use an unscented concentration of 5% -6% so that you can safely and easily dilute it so that it does not leave any residual odors. Make sure you work in a well-ventilated area.[5]

    • Fragrant bleach products are often used for washing.
  2. Clean the surface with detergent and warm water. Bleach is an excellent cleaning and disinfecting solution, but dirty surfaces must be cleaned first. Use warm water and add a few drops of detergent. Scrub the surface with a sponge or washcloth to remove dust, dirt and debris from it.[6]

    • Use a scrubbing brush to remove stubborn stains and debris from the surface.
  3. Rinse the surface with clean water. Use a hose or cloth dampened in clean water to rinse the surface before using the bleach. Make sure you remove traces of soap so that no one can potentially react with the bleach.[7]

    • It is very important that there is no soap left on the surface. Some soaps may have ingredients that can produce a toxic gas if combined with bleach.[8]
  4. Mix bleach with cold water. Fill a bucket with cold, clean water. Measure out the bleach in a measuring cup and pour it carefully into the water. Stir the solution with a pipe stick so that it is completely combined.[9]

    • Never use undiluted bleach to disinfect surfaces.
    • Hot water decomposes the active ingredient in the bleach, making it unusable. Always use cold water when diluting your bleach to use it to disinfect and disinfect.
    • Be careful not to overheat the solution to avoid inhaling the vapors.
  5. Wipe floors, sinks and household surfaces and then allow them to dry. If you use the bleach to disinfect and disinfect household surfaces, use a brush, mop, towel, sponge or washcloth in the solution and wipe the surface. Allow the bleach to air dry and clean the surface completely.[10]

    • It takes at least 10 minutes for the bleach to completely disinfect a hard surface, so do not rinse it off. Let it air dry on its own.[11]
    • Bleach is safe to use on hard surfaces such as floors, sinks, toys and walls.
  6. Soak cleaning tools in diluted bleach for 30 minutes and then rinse them. If you used a brush, mop, towel, sponge or washcloth to disinfect the surface, they must be completely disinfected. Soak them in the bucket of bleach for half an hour and then rinse them with clean water.[12]

    • Make sure you wear gloves when lowering and removing tools.
  7. Use dilute bleach within 24 hours. Once the bleach is diluted, use it while it is still healthy and strong enough to disinfect your surfaces. The diluted bleach begins to break down and is less potent after 24 hours, so discard it the next day.[13]

    • You can label and date the solution to make sure it is still fresh.

[[[[Edit]Getting rid of mold on hard surfaces

  1. Use bleach to kill mold on floors, countertops and hard surfaces. Bleach can be used as an effective way to kill mold on hard surfaces. Use it to get rid of mold on floors, countertops, walls, tiles, concrete and other hard surfaces around your home that may have mold on them.[14]

    • Do not use bleach to get rid of mold on fabrics or porous surfaces such as wallpaper as it may damage or discolor them.
  2. Mix 5% -6% bleach with cold water. Fill a bucket with cold water, not hot, as hot water makes bleaching ineffective. Carefully measure out the bleach and add it to the bucket. Mix the solution with a cane.[15]

    • Be careful not to inhale the fumes. Wear a mask and work in a well-ventilated area.
    • Killing mold requires a stronger bleaching solution than just disinfecting surfaces.
  3. Scrub rough surfaces with a stiff brush before applying the bleach. If you are cleaning a rough wall or a floor that has mold on it, take a stiff brush and give it a good scrub to break up the mold.[16]

    • Breaking up the mold helps the bleach to penetrate it more efficiently.
  4. Wash the moldy surfaces with the bleach mixture. Use a sponge or washcloth and soak it in the bleach solution. Wipe the bleach over all moldy areas to start killing the mold.[17]

    • Soak the sponge or cloth to add more bleach if needed.
    • Wear gloves and eye protection to protect yourself.
  5. Rinse off the bleach with clean water and allow the surface to dry. The strong bleach solution can damage and discolor surfaces if left on them for too long. Use cold, clean water to rinse the surface well so that all bleach is gone. Then let the surface air dry on its own.[18]
    Disinfect with bleach Step 16.jpg
    • Turn on some fans to increase circulation and speed up the drying process.
    • You can spray the surface with clean water or wipe it with a clean cloth soaked in clean water.
  6. Discard the diluted bleach after 24 hours. Diluted bleach begins to break down and become less effective. Use the bleach solution as soon as you mix it. When you are done, or the next day, throw away any remaining bleach.[19]

[[[[Edit]Tip

  • Use a milder disinfectant if you can, such as Borax or disinfectant soap. Bleach is harsh and should be used as a last resort.

[[[[Edit]Warnings

  • Never bathe in bleach. Household bleach irritates the skin and can cause long-term damage.[20]
  • Do not gargle or drink bleach, even if it is diluted. You can cause serious burns and it does not take much bleach to cause serious health problems or become life threatening if you swallow it.[21]
  • If anyone accidentally gets bleach, contact your local poison control office immediately.
