Bricks are highly durable, but that doesn’t mean they’re indestructible. Not only are they exposed to the elements, but brickwork is also susceptible to water damage, mould and general deterioration.
Removing bacteria
All construction materials can form the perfect habitat for mould and bacteria to grow. If you live in areas prone to rain and the bricks don’t receive much sunlight, bacteria - some of them harmful - can thrive.
Structural integrity
The porous surface of bricks means they can quickly gather dirt and moisture, resulting in the growth of algae. Over time, the growth can compromise the stability of the brickwork, which impacts your building’s structural integrity.
Regular maintenance can prolong your building’s lifespan and ensure it maintains its structure for years.
Aesthetic appeal
Let’s not forget that nobody wants to have an ugly home. Curb appeal is also essential if you plan on selling up and moving on. According to Martha Stewart, some homebuyers value curb appeal over anything else.
Ageing and dirty bricks might not seem like a big deal, but simple cleaning is essentially a facelift for your building’s exterior.

How to do it
So, now you know why it’s necessary to keep your bricks looking great, it’s time to reveal the best ways to clean them. While some people prefer to hire professional brick cleaning services, following these tips means you can tackle a variety of stains alone.
Efflorescence
You’ll immediately notice efflorescence for its white colouring, which appears across the bricks when soluble salts form on their surface. Clay bricks contain salts, which can dissolve when exposed to moisture and then reform into a white powdery stain.
In most cases, efflorescence happens when constructing a building or not storing the bricks in a cool, dry place away from moisture. However, if you experience it, you can either wait for it to fade naturally or use a damp sponge to wash the stain away gently.
Grime and dirt
While dirt and grime are inevitable with brickwork, they’re usually harmless. However, it does impact the aesthetics of your building, and a simple cleaning will have it looking fresh again.
In most cases, you can use a simple detergent and gently wash the dirt away, but metal brushes and wire tools can damage the surface.
Gentle pressure washers can be beneficial, but you should avoid using a high setting.
Metallic stains
Most clay bricks have iron, and some manufacturers also use magnesium when producing them. When these bricks are exposed to moisture, a natural reaction occurs, bringing the iron to the surface and causing a stain.
If magnesium is present, you might also notice a black or dark brown stain. Specialists advise leaving the stains to reduce naturally, but you can use a file on the mortar joints to speed up the process.
Vanadium stains
Vanadium stains have a distinctive yellow/green colour, making them unsightly. However, using a dilute oxalic solution can remove them. Other solutions - particularly ones containing hydrochloric acid - can worsen the stains.
Algae and mould
Areas of the building’s exterior that don’t receive much sunlight typically experience higher levels of mould and algae. If the problem is relatively minor, you can use a pressure washer to remove it, but excess water might cause additional issues.
Chemical treatments such as biocides are best for stubborn mould and algae. Once applied to the brickwork, they’ll remove stains and prevent further growth. However, be sure to read the instructions, as chemicals can be hazardous when not handled correctly.
Mortar and cement stains
Mortar and cement stains are usually avoidable, but poor bricklaying work can also result in residues that run along the bricks. When this happens, the best thing to do is wait for the mixture to dry completely, avoiding it spreading across the surface.
There are cleaning products designed to remove dry cement, but it’s also a good idea to contact a professional if you are unsure how to eliminate the stains.
Peacocking
Some people notice stains around blue bricks, also known as peacocking. It usually happens when the mortar is too wet, but saturation of the brickwork can also be an issue.
Peacocking will eventually fade; the best thing is to leave it and wait for nature to take its course.
Preventative measures
Sure, there are plenty of ways to clean stained bricks, but prevention saves time and money. Here are some ways to reduce the likelihood of staining:
⦿ Focus on Quality Bricks stored in dry conditions are less likely to develop problems when you’re laying them. If you buy bricks from a reputable supplier, you can be sure of their quality.
⦿ Mortar Choices When choosing mortar, ensure it’s compatible with your brick type and prepare it according to the instructions. Wet mortar can lead to stains, but using the right mixture prevents this.
⦿ Use Sealant A suitable sealant can add a layer of protection to your brickwork, ensuring moisture doesn’t penetrate it.
⦿ Ensure Drainage Poor drainage is one of the most significant risks to bricks. Ensure the gutters are working correctly to prevent damage.
