A dry sponge works using which process?

A dry sponge primarily works using the process of adsorption. This refers to the ability of the sponge to attract and hold particles, such as dirt and unwanted substances, from a surface onto its own structure. Unlike absorption, where a substance is drawn into the entire volume of a material, adsorption occurs at the interface between the sponge's surface and the particles it comes into contact with.

The nature of a sponge allows it to effectively capture and retain these particles on its surface without necessarily pulling them deep into its material. The surface area of the sponge is instrumental in this process, allowing it to attract more particles through physical and chemical interactions.

Understanding adsorption is crucial in carpet cleaning, as it helps technicians effectively remove residues and impurities from carpets and upholstery surfaces. Recognizing this process highlights the importance of using appropriate cleaning materials and methods that can enhance the efficiency of capturing and removing unwanted substances during the cleaning process.
