Concrete is a very good building material. This is strong, has high compression power and can load large amounts of load without collapsing. Concrete is porous material. This absorbs almost all types of liquids. Dirt tends to stick to concrete because of its rough texture.

Fortunately, concrete can be cleaned effectively by using methods such as pressure cleaning, which is a method where water jets are sprayed on the concrete surface with pressure ranging from under 3000psi up 10,000psi.

However, some of these disinfectants reacted with coloured concrete walls, causing the colour to peel.  Therefore, the filling test in some corners of the wall is needed to ensure that chemicals do not cause damage. Cleaning, after all, is intended to improve the appearance of the wall rather than lower it further.
