Water Cleaning Methods
- Water Soaking
A slow, steady flow of water is used over the facade to relax dirt and cleanse it away. This is a very effective method on limestone and glazed brick kind of facades.
- Pressure Washing
In this method, pressurized water blasts contaminants away from the facade. This procedure is effective on stone, masonry and concrete for the removal of light to moderate atmospheric and organic staining. Facades with grease and oil stains may require hot water cleaning.
- Chemical Cleaning Methods
This cleaning method uses chemical products to rout out the tough facade stains, by dissolving them and allowing them to be rinsed away. Though the list of available chemical cleaners for different types of facade surfaces is long and varied, they fall into one of the following four categories: Acidic Cleaners, Alkaline Cleaners, Organic Solvents and Special Detergents.
- Abrasive Cleaning Methods
Abrasive cleaning is a unique method, which is designed to completely remove the outer portion of the substrate on which the stain settles, rather than merely dissolving and washing away the stain alone.
- Aluminium Cleaning Methods
Mild cleaners, abrasive and etching cleaners, solvent and emulsion cleaners, steam cleaners and power-driven brushes are among the methods used in the cleaning process of aluminium facades.
