Which cleaning agent is classified as heavy-duty?

The classification of cleaning agents depends on their chemical composition and intended use. Solvents are often classified as heavy-duty cleaning agents because they are designed to dissolve or disperse a variety of contaminants, including grease, oils, and some types of resins. They work effectively on tough, industrial-strength stains and are typically used in environments where heavy accumulation of dirt or oil is present, such as in maintenance and mechanical applications.

Solvents can penetrate and break down these stubborn compounds more vigorously than milder cleaning agents. Their effectiveness in tackling heavy deposits makes them suitable for tasks requiring robust cleaning solutions.

In contrast, soap and synthetic detergents are generally milder and more suited for light to moderate cleaning tasks. Acid cleaners are specialized agents often used to remove mineral deposits, rust, or corrosion but may not be classified as heavy-duty in the same way solvents are, given their specific application and potential to damage certain surfaces if not used correctly.
