How to Get Rid of Mould from Your Bathroom

How to Get Rid of Mould from Your Bathroom

, by Aussie Pharma Direct, 9 min reading time

Dealing with mould growth can be a common nuisance for many homeowners, and the bathroom is often a prime breeding ground. You step into your bathroom, ready for a relaxing shower or a quick brush-up, only to be greeted by those unsightly patches of black mould lurking in the corners of the ceiling, mildew on shower curtains or in the grout lines. Mould isn't just unsightly; it can also pose health risks and compromise the cleanliness of your bathroom. 

In this guide, we'll explore the ins and outs of mould: what it is, why it thrives in bathrooms, and most importantly, how to effectively remove it. So, let’s get to it!

Types of mould in the bathroom

Mould is a type of fungus that thrives in damp, humid environments, making bathrooms an ideal breeding ground. It reproduces through tiny spores that are invisible to the naked eye and can easily spread through the air.

There are two types of mould commonly found in bathrooms:

  • Black mold (Stachybotrys chartarum) - This type of mould is notorious for its dark green or black colouration and can cause serious health issues if left untreated. Black mould typically thrives in areas with prolonged moisture exposure, such as shower walls, ceilings, and grout lines.
  • Mildew - Mildew is a common type of mould that appears as white or gray patches on bathroom surfaces. While less harmful than black mould, it can still cause respiratory issues and aggravate allergies, especially in individuals with sensitivities. 

What causes mould in the bathroom?

Key factors contributing to mould growth in bathrooms:

1. Moisture:

  • High humidity - Bathrooms are typically high-humidity environments due to activities like showering, bathing, and handwashing. Moisture from these activities accumulates in the air, providing an optimal breeding ground for mould.
  • Poor ventilation - Inadequate ventilation exacerbates moisture buildup by trapping humid air inside the bathroom. Without proper airflow, moisture lingers on surfaces, promoting mould growth.
  • Leaking fixtures - Leaky faucets, pipes, or shower heads contribute to moisture accumulation in the bathroom. Even minor leaks can create damp conditions conducive to mould growth.
2. Warmth:
  • Temperate conditions - Mould thrives in temperatures ranging from 77°F to 86°F (25°C to 30°C). Bathrooms often maintain a comfortable temperature range, especially in homes with central heating systems, providing favourable conditions for mould growth.
3. Organic matter:
  • Cellulose-based materials - Mould requires organic matter to feed on for growth, and bathrooms offer plenty of suitable surfaces, including drywall, wood, wallpaper, and even soap scum. These materials provide nutrients for mould spores to colonise and spread.
4. Lack of sunlight:
  • Dark, damp spaces - Mould thrives in dark, poorly lit areas where sunlight cannot penetrate. Bathrooms with limited natural light or areas that remain shaded due to architectural features are more susceptible to mould growth.
5. Inadequate cleaning:
  • Neglected surfaces - Infrequent or ineffective cleaning allows mould spores to accumulate on bathroom surfaces over time. Mould can quickly take hold in neglected areas such as grout lines, corners, and behind fixtures.
6. Lack of maintenance:
  • Untreated water damage - Failure to address water leaks or moisture issues promptly can lead to structural damage and mould growth within walls, ceilings, and flooring.
  • Uncleaned ventilation systems - Dust and debris buildup in bathroom exhaust fans or air vents can hinder proper airflow, exacerbating moisture retention and mould growth

How to clean mould in the bathroom?

Here are some general tips for effectively cleaning mould from bathroom surfaces:

1. Safety first

Before you begin cleaning, ensure proper ventilation by opening windows or using exhaust fans. Additionally, wear protective gear such as gloves and a mask to prevent exposure to mould spores.

Choosing a suitable PPE can make all the difference when it comes to protection. Check out the range of gloves and face masks available at Aussie Pharma Direct.

2. Use protective measures

To prevent the spread of mould spores, cover nearby surfaces and fixtures with plastic sheeting or towels before you start cleaning.

Using SAN-AIR™ Surface Mould Remover

For a more powerful and eco-friendly solution, consider using SAN-AIR™ Surface Mould Remover. This innovative product is formulated with 100% natural actives that effectively remove visible mould, neutralise toxic mould and mildew, eliminate bacteria, and banish unpleasant odours.

Here's how to clean with SAN-AIR™ Surface Mould Remover:

  • Adjust the nozzle of SAN-AIR™ Surface Mould Remover to achieve a fine spray for even application on the surface you want to clean.
  • Before proceeding, test the spray on a small, inconspicuous area of the surface to gauge compatibility and observe any temporary changes in colour.
  • Spray the surface mould remover evenly to coat the mould-infected area.
  • Allow the spray to sit for 15 minutes. After the waiting period, use a clean, dry cloth to wipe off the mould. Ensure thorough cleaning and avoid reusing dirty clothes to prevent mould spread.
  • If any mould residue remains, repeat the application and wiping process until all traces of mould have been completely removed from the surface.
  • Give the cleaned surface a final spray with SAN-AIR™ Surface Mould Remover and allow it to air dry naturally.

How to avoid mould in the bathroom?

Preventing mould growth in the bathroom requires proactive measures to control moisture and maintain cleanliness. Here are some tips to help you avoid mould in your bathroom:

1. Ensure proper ventilation
  • Use exhaust fans during and after showers to remove excess moisture from the air.
  • If your bathroom doesn't have a fan, crack open a window to promote airflow.
  • Leave bathroom doors open after showering to allow moisture to dissipate.
2. Fix leaks promptly
  • Inspect plumbing fixtures regularly for leaks and repair any issues promptly.
  • Pay attention to dripping faucets, leaking pipes, and any signs of water damage.
3. Keep surfaces dry
  • Wipe down wet surfaces such as shower walls, bathtub edges, and sinks after use.
  • Use a squeegee on shower walls and doors to remove excess water and prevent mould-friendly conditions.
4. Seal grout lines
  • Seal grout lines between tiles to prevent moisture from seeping into the walls.
  • Regularly inspect grout for cracks or deterioration and repair as needed.
5. Clean regularly
  • Develop a regular cleaning routine for your bathroom, focusing on areas prone to mould growth such as shower stalls, bathtub edges, and sink drains. Use mould-inhibiting cleaning products or natural remedies like vinegar or SAN-AIR™ Surface Mould Remover to clean surfaces and prevent mould growth.
  • Keep bathroom surfaces free of organic matter such as soap scum, hair, and skin flakes, which can provide nutrients for mould growth.
  • Clean shower curtains, bath mats, and towels regularly to prevent mould buildup.
6. Use mould-resistant products
  • Choose mould-resistant paint for bathroom walls and ceilings to discourage mould growth.
  • Consider installing mould-resistant drywall or cement board in areas prone to moisture.

Using SAN-AIR™ Mould Gone for long-term protection

For those seeking long-term protection against mould and bacteria in the bathroom, consider using SAN-AIR™ Mould Gone. This advanced formula is designed to not only remove airborne bacteria, mould, fungus, and spores but also prevent their return, providing round-the-clock protection for up to 3 months.

SAN-AIR™ Mould Gone comes in a reactive gel form, making it ideal for enclosed spaces like the bathroom. You only need to place the container in the desired location within the bathroom, ensuring it is easily accessible and away from direct contact with water.

For the product to work effectively, keep the bathroom windows closed for the initial 48-72 hours after placement. This allows the reactive gel to disperse and circulate within the enclosed space, targeting mould and bacteria at the source.
