Composite cladding is indeed resistant to mould and mildew. What this signifies is that unlike wood that supports mould and mildew, the composite cladding will not. But certain conditions can make mould and mildew thrive on your composite cladding. This write-up explains how you can remove mould and mildew from your composite cladding surface.
Conditions that Favours the Growth of Mould and Mildew on Composite Cladding
We stated before that certain conditions favoured the growth of mould and mildew. Let’s consider the condition one after the other.
No Maintenance
Composite cladding is like other building materials that need regular maintenance to make it last longer. This implies that you have to clean your plastic wood cladding regularly. Cleaning your composite cladding will not only make it look good, but it will increase the durability of your cladding. But what will occur if you don’t maintain your composite cladding?
Your composite cladding will lose its durability. So, if you let organic matters decay on your composite cladding, the decayed spots will serve as a breeding ground for mould and mildew. If branches of trees should fall and rest on your cladding, the tree branches will decay and serve as a breeding spot for mould.
Mould will produce black spots on your cladding that will make it less attractive. The solution to mould and mildew is for you to clean your cladding. If you clean your composite cladding regularly and remove decay organic matters from the surface, mould and mildew will not thrive on it.

Scratches on the Surface of Your Composite Cladding
Another thing that can let mould and mildew thrive on the surface of your composite cladding is when there is a scratch on it. The composite cladding has an extra layer of plastic on its surface texture that makes it absorb less moisture.
If you peel or scratch the surface, the spot will readily absorb moisture. This will happen if the scratch is deep and reaches the timber part of your composite cladding. When the wood part of composite cladding absorbs water, the wood will decay.
Note that anything decay or rot will serve as a breeding ground for mould and mildew. If something should scratch your composite cladding surface and the spots decay, mould will thrive on the decay spots. The solution is for you not to scratch your cladding.
Removing Mould and Mildew from Your Composite Cladding
If mould and mildew should grow on the surface of your composite cladding, you can remove it. The right way to remove mould and mildew from your composite cladding is by cleaning the spots with soapy water or vinegar. But first, how do you identify mould and mildew?
Mould and mildew are certain types of fungi that thrive in humid and damp areas. They thrive in a wet environment and spread quickly all over your composite cladding. Mould is a fungus that grows in the form of black or green patches and goes beneath the material it grows on.
Mildew does not go beneath but remains on the surface of your composite cladding. Mildew growth on composite cladding is more common than mould.
Step One – Identify the Spots
You have to identify the spots that mould and mildew grows on so that you will know where to clean. Then you can try to scrape the mould or mildew so that washing with soapy water or vinegar will be easy.
Step Two – Mix Your Soap
The next thing t do if you want to remove mould and mildew from your composite cladding is for you to mix the soap or vinegar that you will use to wash your cladding. If you want to utilise soap to clean your composite cladding, look for a bucket of water and a good soap.
Then you should add soap to the water and mix until it foams. You can also use a special composite cladding cleaner for the task if you want to. Vinegar is another thing you can use to clean your composite cladding. Mix your vinegar and water so that you will use it on your composite cladding.
Step Three – Scrub Your Composite Cladding
Depending on whether you are using soap or vinegar, you should pour the mixture on the mould and then scrub. If you are making use of soap, spray the soapy water on the spots that mould and mildew grow on and then scrub.
You should use a brush that is not too strong to clean your composite cladding. If you are using vinegar, you should sprinkle baking soda on the mould or mildew and then spray the vinegar on the mould. Then you should scrub the way you did with soapy water.
Step Four – Rinse Your Composite Cladding
After scrubbing your composite cladding until it is clean, you should rinse it with water. You can utilise a hose to spray water on the surface of your composite cladding.
Conclusion
How to remove mould and mildew from the surface of your composite cladding is easy. You must maintain your cladding by cleaning the surface with soapy water and then scrub it with a brush.
