Mould on Ceilings: How to Clean Off

Mould on ceilings is a common problem that can cause health issues, damage to ceilings, and an unsightly appearance. It is important to address mould as soon as it is noticed to ensure a healthy environment and clean ceiling. In this blog post, we will cover the importance of cleaning mould off ceilings, how to identify and eliminate the source of mould, and the three best cleaning methods for removing mould.

Identifying and Eliminating the Source of Mould

Before you can begin to clean the mould off your ceiling, it is important to identify and eliminate the source. Here are some tips for identifying and eliminating the source of mould:

  • Check for a roof leak: Water from a leaking roof is the cause of most ceiling mould. Without repairing the leak, the mould will return.
  • Improve circulation and ventilation: Mould often develops in kitchens and bathrooms which lack proper ventilation. Add extractors to release the moisture and fans to circulate the air.
  • Increase natural light: Mould grows best in dark spaces. Keep windows and curtains open to let the sunshine in. This prevents mould colonies from growing on the ceiling.
  • Improve insulation: Poor insulation encourages mould growth. When cold air from the outside meets warm air from the inside, it causes condensation. Improving insulation in your home creates a barrier, reducing mould growth conditions.
  • Check the other side of the ceiling: You may have mould on the other side of your ceiling. Removing the underside mould will not eradicate the mould problem.
  • Add dehumidifiers to the kitchen and bathroom: Mould grows in damp, warm conditions. Removing the humidity from the air reduces a colony’s ability to grow.

Keep the bathroom door open and the fan on after showering: Allow the humidity in your bathroom to escape. Leave the bathroom door open and the extractor fan on for 15 minutes.

Hang your towels in a different room: Wet towels add humidity to the bathroom. Drying your towel in another room reduces the mould growth conditions by lowering the humidity levels.

How to Clean Mould off a Ceiling

There are three main cleaning methods for removing mould off ceilings: vinegar, bicarbonate of soda, and hydrogen peroxide.

Cleaning with Vinegar:

Vinegar is a natural liquid that is useful for many things, including removing stains and killing germs. This mild acid kills 82% of mould types.

  • Pour distilled white vinegar into a spray bottle.
  • Spray it directly onto the mould and leave for an hour.
  • Wipe the vinegar off with water and let the area dry.

Cleaning with Bicarbonate of Soda:

Bicarbonate of soda is a mild powder that absorbs moisture, keeping mould away. It is also safe to use around children and animals.

  • Combine a teaspoon of bicarbonate of soda with water in a spray bottle and shake until it has dissolved.
  • Spray it directly onto the mould and leave for a few minutes.
  • Use a scrubbing brush or sponge to remove the mould, then wipe the solution off with water.
  • Spray the solution on the area again and let it dry.

Cleaning with Hydrogen Peroxide:

Hydrogen peroxide is anti-viral, anti-fungal, and anti-bacterial. It can be used to clean mould from ceilings, walls, and floors. However, it should be used with caution as it acts like bleach and affects delicate surfaces.

  • Pour concentrated hydrogen peroxide into a spray bottle.
  • Spray it directly onto the mould and leave it for ten minutes.
  • Use a scrubbing brush to remove the mould and stains.
  • Wipe the surface with water and let it dry.

Comparison of the Three Cleaning Methods:

All three cleaning methods are effective at removing mould from ceilings. Vinegar is the most commonly used method due to its availability and affordability. Bicarbonate of soda is also effective and has the added benefit of absorbing moisture, which helps prevent mould from returning. Hydrogen peroxide is the most potent of the three, but it should be used with caution as it can damage delicate surfaces.


In conclusion, mould on ceilings must be addressed as soon as it is noticed to ensure a healthy environment and clean ceiling. Identifying and eliminating the source of mould is crucial to preventing its growth. The three main cleaning methods for removing mould from ceilings are vinegar, bicarbonate of soda, and hydrogen peroxide. All three methods are effective and safe to use, but hydrogen peroxide should be used with caution.

It is important to take precautions when cleaning mould, such as wearing gloves and a mask. Seek permission from the landlord if you are renting, and follow the instructions carefully for each cleaning method.

3 Easy mould removal steps for ceilings

When it comes to removing mould from your ceilings, there are two options, you can remove the mould yourself or you can hire a professional mould removal service to do it for you. In this article, we’ll look at how you can remove the mould yourself. Follow this simple guide on how to remove mould from your ceilings and get back to enjoying the space in your home you never thought you’d see again!

1. Clean and Dehumidify

The first step in getting rid of mould is cleaning your ceiling. Scrub it with bleach or another cleanser meant for mould. It’s important that you use proper safety equipment and try not to breathe in too many airborne mould spores during cleaning. Afterwards, dehumidify your room for at least 72 hours—dehumidifiers work best at drying out moisture and killing potential mould spores. Drying out your room will make sure that any remaining water doesn’t become a new source of growth. If you can’t buy a professional-grade dehumidifier, leave a space heater on in your room until it has dried out completely (not just until the humidity level feels dry).

2. Clean Up Water Damage

When it comes to mould removal, prevention is key. Mould and mildew are two of nature’s most stubborn pests. They can spread through small openings and collect in hidden areas, often undetected by naked eyes. In order to get rid of mould successfully, you need a strong plan. WTO avoid a recurring problem, make sure that your space is well-ventilated and that water isn’t pooling on your ceiling (check your air conditioner drip pans, rain gutters and roof leaks). Follow these steps: (1) Stop any water leaks immediately; (2) remove all porous materials that have been touched by water; (3) dry all affected surfaces with fans and dehumidifiers; You don’t need an expensive restoration service to fix up water damage from mould – just follow these easy steps.

3. Use an Anti-Mould Paint

If you have a serious mould problem, start using anti-mould paint. Most paints will claim to be anti-mould however unless they are specifically designed for use in areas prone to mould growth, they won’t stand up very well. Always check with manufacturers before buying and make sure that your ceiling paint is suitable for use around damp areas. Whatever type of paint you buy, apply it according to their instructions and allow it time to dry completely before exposing it to moisture again or painting over it.


Mould removal is not a fun task but with these steps, it shouldn’t be too difficult. Remember, when trying to remove mould off your ceilings, wear appropriate safety equipment because some moulds are dangerous if inhaled. If you have any doubts, contact a professional mould removal service provider and don’t take matters into your own hands. Following these steps will ensure the safe removal of mould from your ceilings. These three mould removal steps apply no matter where in your home you need to remove mould from the ceilings.
