Stubborn stains may require using a washing machine or other cleaning equipment with detergent. Move the hose back to the front and spray from side to side.
The next method is pressure cleaning. This is known as pressure cleaning because it uses high-pressure water to clean it. The high food pressure increases its strength, which removes dirt from the concrete surface.
Loose surface materials should be washed before starting pressure washing. Different sprayers and nozzles can be used to achieve different effects.
It can be used as heavy-duty laundry detergent and laundry detergent but is generally 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 by bacteria and similar plants and suitable for hotels, hospitals, and cafes. However, it is slower than any of the above methods, so it can be used in combination with one or both methods to achieve the desired effect.
