With these simple ways, you may safely eliminate unattractive and possibly harmful mould from the bathroom and other moisture-prone areas, as well as keep it at away.

Mold splotches on the walls or ceiling are an all-too-common problem in any part of the home where moisture levels are high. While mould may grow anywhere along a wall, it is most commonly discovered either high up near the ceiling, low down near the floor, or creeping along trim or baseboard borders. This inconvenient and sometimes dangerous issue is most common in bathrooms with frequently used showers or tubs, but it may also impact wet basements, kitchens, or laundry rooms. If circumstances are wet, ventilation is inadequate, and temperatures are high, airborne, invisible mould spores—which may be found almost anywhere—will happily settle in and develop.

Stachybotrys chartarum, often known as black mould, is the most dreaded form of mould that can cause chronic respiratory irritation, headaches, and persistent tiredness. According to the Centers for Disease Control and Prevention, black mould requires continual wetness to develop, not simply occasional moisture from the shower, therefore it’s more likely that your problem is caused by a less deadly mould. However, a significant mould infestation can cause or worsen respiratory or immune system problems.

If mould is forming in a moist location, it is recommended to speak with a mould remediation specialist for professional cleaning services. The good news is that you should be able to handle most common mould problems on your own. Continue reading to learn how to cure the typical mould.

How To Remove Mold From Walls

In a spray bottle, combine one part bleach to three parts water and completely soak the mouldy portions of the wall. As you work, open a window and/or have a fan blowing; bleach smells are unpleasant and can irritate the lungs. Allow the bleach to sink into the mould on the walls for several minutes before removing the spots with a scrub brush. If the stains are widespread or deep, the treatment may need to be repeated to eliminate all discoloration.

Kill the Mold

While bleach is effective in killing surface fungus and removing mold-caused stains on walls, it does not penetrate deeply into the drywall, leaving the mold’s “roots” unaffected. That implies the issue will most likely return, possibly within days. Simply spray undiluted white vinegar onto the afflicted area and allow it to dry to destroy mould under the surface. Don’t worry about the stink; it will go away once the vinegar is totally dried.

Make Sure It Doesn’t Come Back

After you’ve eradicated all mould from the walls, use the following preventative actions to keep those surfaces looking good:

  • Wipe up any puddles or spills as soon as possible.
  • After a shower or bath, keep the bathroom door open for at least 20 minutes with the air fan running or the bathroom window open to enable humidity to dissipate.
  • Be on the lookout for plumbing leaks. Fix them quickly away—most forms of mould require just 24 to 48 hours of wetness before spores begin to grow, and black mould becomes more likely the longer water leaks go unnoticed.
  • Spread out damp towels to allow them to dry rapidly.
  • Shower with the bathroom door open if possible to prevent moisture from accumulating in the confined space.
  • Set a canister of moisture-absorbing desiccant (often silica gel or salt) in a corner of your bathroom, or run a dehumidifier if you live in a particularly humid region.
  • After each usage, squeegee the shower walls and glass doors to remove the moisture that fosters mould growth on your walls and to avoid unattractive hard-water and soap-scum accumulation.
  • When it’s time to repaint or renovate the bathroom or mold-prone rooms, choose mold-resistant paint.
  • Clean the bathroom once a week with your preferred disinfectant, whether it’s bleach, vinegar, or a professional cleaner, and remember to scrape behind shampoo bottles and other shower essentials where mold may accumulate.

Know Your Mold and Mildew

Mold may grow in your home anywhere there is a lot of moisture, especially if it is allowed to stay for a lengthy period of time. Mold typically grows on the walls, ceilings, and floors of homes when moisture control is inadequate. Mold thrives in locations such as basements, shower walls, and windowsills. Mold and mildew are essentially the same thing; mildew is a general term used to describe various small mould concerns in the house, such as on shower tile grout. Some moulds, on the other hand, may become extremely hazardous to humans if allowed to grow unchecked.

Mold may cause allergic responses, asthma, and other respiratory problems, and it is especially dangerous for young children, the elderly, and those who already have respiratory diseases or have compromised immune systems. Mold can appear in a variety of forms and hues, none of which correctly identify the species of mould. It does, however, frequently appear in different shades of black, white, green, or blue, as well as countless combinations of these and other hues.

What is Black Mold?

Black mould is frequently discovered inside homes when there has been severe moisture damage to the wallboard and other surfaces. Much is made of the “toxicity” of this form of mould, although the mould itself is not dangerous. It does, however, have the ability to create mycotoxins, which can be harmful to humans and pets depending on the species of mould. When eradicating moulds, a good rule of thumb is to “take caution,” especially if there are a lot of them.

What is White Mold?

White mould is commonly seen on walls and other structures in chilly, damp areas such as basements. It is frequently mistaken with efflorescence, a mineral deposit formed on foundation walls and other brick surfaces as a result of water seepage. You may spray it with water to determine if it’s mould. If it dissolves, it is most likely a mineral deposit; if it does not dissolve, it is most likely white mould.

What is Blue Mold?

Another typical hue of household mould that can occur in moist parts of the home, such as on bathroom walls and ceilings, is blue mould. Moisture that accumulates on walls after lengthy, steamy showers may provide the ideal environment for this mould to grow.

What is Green Mold?

Green mould, like blue mould, is quite common in homes and may be found in moist locations such as shower walls and damp corners. Green mould, like other moulds, may be eradicated by washing it away with a bleach solution.

Control Moisture

There is no method to completely eradicate mould and mould spores inside, according to the United States Environmental Protection Agency (EPA). Controlling indoor moisture is critical to mould control:

  • Repair Water Issues (Leaks, etc.) – Repair leaks as soon as you discover them. A leaky basement or roof not only causes immediate structural damage, but the wet regions allow mould to flourish if not addressed. To avoid mould formation, clean and dry any moist or wet construction materials within 24 to 48 hours. If you do not, and mould infiltrates them, they must be removed in order to entirely resolve the mould problem. See How to Repair Basement Leaks and First-Aid for Roof Leaks for more information on repairing leaks.
  • Reduce Indoor Humidity – The more humid your house is, the more probable mould spores will thrive. Reduce humidity by boosting ventilation in your house to keep the air from getting heated and stagnant. Large appliances, such as washers and dryers, as well as your bathroom and kitchen, should be vented. Turn on air conditioners and dehumidifiers as well to decrease moisture in the air. If you don’t already have an air conditioner or a bathroom exhaust fan, check How to Install a Window Air Conditioner and How to Install a Bathroom Exhaust Fan.
  • Prevent Condensation – Insulate external walls, roofs, windows, and pipes to decrease the possibility of condensation creating moisture.
