Soft washing and high pressure washing are two common cleaning methods. Soft washing and high pressure washing are two different types of cleaning techniques. Each has its own characteristics and applicable scenarios. They have different ways and functions in cleaning the surface of objects. The following are the main differences between them.
Cleaning method
Soft washing: Use low-pressure water flow and detergent for cleaning, usually with a pressure of less than 60 psi (about 4 bar). Suitable for cleaning more fragile surfaces, such as roofs, exterior walls, windows, etc., and can effectively remove dirt without damaging the surface. The role of detergents is more important, decomposing dirt through chemical reactions, especially biological dirt (such as moss, mold, etc.).
High pressure washing: Use high-pressure water flow (usually above 1000 psi (about 70 bar)) to impact the surface and remove stubborn dirt. Suitable for cleaning hard surfaces such as concrete, masonry, vehicles, etc., can quickly and effectively remove oil, dirt, etc. The high-pressure water flow has a strong impact force and can peel off dirt attached to the surface, but may cause damage to some fragile materials.
Application scenarios
Soft washing: Commonly used in areas that need protection, such as residential exterior walls, roofs, and around swimming pools. Suitable for cleaning areas that require gentle treatment to avoid physical damage.
High-pressure washing: Widely used in industrial cleaning, construction sites, car washing and other fields. For heavy dirt and stubborn stains, the effect is significant and fast.
Efficiency and environmental protection
Soft washing: The cleaning process is slower, but due to the use of detergents, good results can be achieved at lower pressures, which is more environmentally friendly.
High-pressure washing: The cleaning speed is fast, but attention should be paid to the use of water resources and possible environmental impacts.
Summary
The choice of soft washing or high-pressure washing depends on the material and dirt type of the cleaning object. Soft washing is a better choice for surfaces that need protection, while high-pressure washing is more effective for stubborn dirt.
