Which factor does NOT affect the cleaning process?

The factor that does not affect the cleaning process is related to the type of food being cleaned. While different types of soil and contaminants (such as grease, sugar, or protein residue) can influence the effectiveness of cleaning, the classification of the food itself does not directly determine how well the cleaning process occurs.

Factors like the type of soil are crucial since different soils require different cleaning agents or techniques. The length of time that the cleaning agent remains in contact with the surface impacts how well it can dissolve or emulsify the contaminants, and the temperature of the water can enhance the cleaning effectiveness by influencing the solubility and efficacy of the cleaning agents.

Therefore, when considering the process of cleaning, it is not the type of food that dictates how well the cleaning takes place, but rather the nature of the soil associated with the food that plays a significant role.
