It can be very harmful if left unchecked and mould contamination occurs on any part of your home it is best to make the necessary cleaning mould off walls and other surfaces as soon as possible. The longer mould has access to a surface, such as on the ceiling or wall, the more extensive the damage can become. The first step in cleaning mould off walls is to remove the affected object from a position where it will not cause additional damage. Many pieces of furniture are made from wood and while they look nice, they can easily sustain damage over time. If you have any wooden pieces on the exterior of your home, this can be a good place to start cleaning mould off walls.
You can purchase mould cleaning products from most major retailers, or you can make your own. One of the best products for this task is a toxic gas solution. The product contains a variety of organic chemicals such as bleach, water, hydrogen peroxide and chlorine. The hydrogen peroxide acts as a bleach, which helps to break down the organic material on the mouldy surface, killing any spores. In addition, it also helps to kill any bacteria or mould that remains.
The second step is to use water and a soft cloth to gently remove any stains that might be on the surface. This will help to prevent any water spots from setting into the mould and causing damage. You will then want to thoroughly scrub the affected areas using a solution of one part bleach to two parts water. This solution works very effectively and it leaves the walls looking like new. You may even find that the stains that did not come off in the first attempt now appear.
If you find that you still have mould on your wall, but it has not damaged any of the underlying materials you should consider cleaning mould off walls with bleach again. Bleach will help to remove any of the more toxic chemicals on the mouldy surfaces and it will help to make them look like new once again. Just use a solution of half bleach to half water and scrub the mouldy surfaces using this solution. It can be quite messy, so it is recommended that you have a shower or bath if you are cleaning mould in the bathroom.
Using a solution of half water to half bleach, you can create a paste that you can apply to the stained area and allow to sit for 30 minutes. After this time the bleach will have soaked into the material and you will be able to wipe away the stain with a clean and fresh cloth. Many cleaning professionals will recommend the use of water-based bleach for many cleaning jobs.
Many cleaning professionals also recommend the use of a bleaching agent when cleaning mould from wood surfaces. This type of cleaning agent works by giving your wooden surfaces a deep cleaning that can remove the remaining mould that still exists. The bleaching agent works by creating a protective layer that makes the wood surfaces easier to clean and helps to seal up any cracks that may exist. You will find that this cleaning agent is often better than regular household cleaners because it does not contain harsh chemicals. These types of cleaning agents can work well on dark wood surfaces where light cleaning methods may not be able to reach the recesses. It is especially useful in removing mould from walls and floors.
If you are dealing with water-related stains then you will need to remove the moisture from the surface and this will require one of the basic cleaning techniques such as sanding wood surfaces or cleaning with mildew killing media blasting. In many cases, you will find that using these simple cleaning techniques is all that is required to remove the stain from your surfaces. If you have an extreme black mould stain, however, it may require the use of other media blasting techniques to get rid of the stain. These techniques are especially useful in removing black mould that has penetrated deep into the wood surface and below-grade boards.
