Instead, brick acid is commonly used on baked clay bricks, such as those found in many modern buildings. However, caution must still be exercised to ensure that the acid is applied and rinsed properly, as prolonged exposure or incorrect usage can lead to permanent damage.

Can Acid Damage Bricks?

Brick acid, also known as masonry cleaner or brick cleaner, contains powerful acidic compounds that can cause damage to certain types of bricks. The acid is designed to dissolve the top layer of brick, which makes it effective for removing dirt, grime, and stains.

However, using brick acid on natural stone surfaces, such as limestone and marble, is a big no-no. The high acidity of the solution can eat away at the surface of these stones, leading to irreparable damage. Additionally, it’s crucial to consider the porosity of the brickwork. Porous bricks may absorb the acid, causing them to break down or weaken over time. Therefore, it’s essential to identify the type of brick and assess it’s susceptibility to acid before using any brick acid.

To minimize the risk of damage, it’s recommended to conduct a spot test in an inconspicuous area before applying the brick acid to the entire surface.
