Why is the hand water hose not suitable for removing grease?

The hand water hose is not suitable for removing grease primarily because it cannot effectively break down and lift away grease from surfaces. Grease is a viscous substance that requires more than just water pressure for effective removal. High-pressure water can help dislodge some debris, but it does not have the capability to emulsify or thoroughly clean away greasy residues. For effective grease removal, appropriate cleaning agents or methods such as degreasers or scrubbing are typically necessary.

While scattering the grease or potentially damaging surfaces might be concerns with using just water pressure, the main issue lies in the inadequacy of water alone to address the properties of grease. Grease requires specific cleaning techniques or substances to ensure complete removal, which a hand water hose is not equipped to provide.
