Soap is highly recommended for washing dishes because it helps to remove grease, food particles, and other contaminants effectively. While water alone can rinse away some dirt and debris, it may not be sufficient to completely eliminate bacteria and other microorganisms that can be present on dishes. Soap works by reducing the surface tension of water, allowing it to penetrate and lift away oils and grime more effectively. It also contains surfactants that help to break down and dislodge stubborn food residue.
Using soap while washing dishes helps to ensure proper hygiene and cleanliness. It aids in removing bacteria, germs, and other pathogens that can be present on dishes, especially after handling raw meat or other potentially contaminated substances. Additionally, soap helps to remove grease, oils, and dried-on food particles that water alone may not be able to remove effectively.
While it is possible to clean dishes with water alone, it is generally not recommended for optimal cleanliness and hygiene. Soap enhances the cleaning process and helps to ensure that dishes are thoroughly cleaned and safe for use.
