Mildew On Bricks

Piled-up dirt and dust on bricks also cause the mildew to grow. It is the reason why mildewed bricks are mainly seen in unmaintained areas. As well as in those that are surrounded by organic materials. 

Mildew in bricks is not immediately visible, but they do cause a musty smell. The smell signs the homeowner that there is mildew growth in the property.

If mixed with warm water, boric acid can be a great help in cleaning mildew in bricks. Spray it on the area and let it stay for two minutes. 


3. Baking soda

5. Water

Pressure washing is another technique in removing mildew. Using this, you will need a high water pressure and a pump.

Although this is an effective strategy to remove molds in bricks, it is not highly advisable to use this technique because it can also ruin the bricks due to pressure. Only professionals should perform pressure washing.
