For places like cobblestones or garages where there is too much room for the methods described above or where there is too much dirt, one of three methods is used. These include water washing, pressure washing and steam washing.
Washing with water refers to using a garden hose or low pressure hose to clean the surface. This is also known as low pressure water scrubbing in the 100 to 200 kPa range.
Stubborn stains may require using a washing machine or other cleaning tool with detergent. Move the hose to the front and spray from side to side. You can also contact the best concrete cleaning company by surfing internet.
The next method is pressure cleaning. This is called pressure cleaning because high pressure water is used to clean it. The high food pressure increases its strength, which removes dirt from the concrete surface.
Loose surface materials should be washed prior to pressure washing. Different sprayers and nozzles can be used to achieve different effects.
It can be used as a laundry detergent and detergent, but is usually not necessary as the high water pressure is sufficient to get the job done.
Steam cleaning, the third method, has the advantage of having a higher pressure than the two methods above. It should be used with an emulsifier or detergent suitable for high pressure steam cleaning.
It is suitable for surface disinfection of bacteria and similar plants and is suitable for hotels, hospitals and cafes. However, it is slower than either of the above methods, so it can be used in combination with one or both methods to achieve the desired effect.
