Yes, pressure cleaning, particularly when not done right, can degrade the concrete, cause pitting and lines in the surface.  To avoid causing irreversible damage to your concrete surfaces it is worth organising a specialist pressure cleaning service.

WashKing’s concrete cleaning service begins with a foam-like (and environmentally friendly) detergent being sprayed to cover the surface. After being left for a few minutes to break down the dirt and grease, we use high-pressure cleaning equipment and a high-quality degreaser to complete the cleaning process. The final result: a dirt-free surface that is ready to be painted or sealed, if you wish.

We use hot or cold water for our concrete cleaning services to ensure we remove all traces of grease, oil, tyre marks, and even gum and graffiti.

To properly clean concrete, we first apply an alkaline detergent foam. Once this has soaked in and broken down the oils and grime, we blast the area with 3500 psi of hot or cold water using the Whirlaway cleaning attachment to minimise mess. The use of hot water in the concrete cleaning process ensures all traces of grease, oil deposits and even graffiti and gum (particularly on tilt-panel walls) are completely removed

Clear or coloured Sealing/Painting is a great way to extend the life of your concrete surfaces, protecting against stains and soiling. So once your concrete has been pressure cleaned and or sealed it will last for years and be easy to keep clean yourself.
