Which category of smoke is known for producing the least amount of residue?

The category of smoke known for producing the least amount of residue is dry smoke. Dry smoke occurs when materials such as wood or plastics burn at high temperatures, resulting in a lighter, less sticky substance. This type of smoke is characterized by fine particles and is typically easier to clean, as it does not adhere as strongly to surfaces compared to other categories of smoke like wet or thick smoke.

Wet smoke, for instance, results from burning low-temperature materials, such as plastics or rubber, which can create a dense, sticky residue that adheres strongly to surfaces and is much more challenging to clean. Similarly, thick smoke is associated with incomplete combustion, leading to larger particles and greater residue accumulation. Dilute smoke can vary widely depending on the conditions of the fire but generally produces more residue than dry smoke.

Therefore, dry smoke stands out as the type associated with the least residue, making it more manageable during restoration processes. Understanding these distinctions is essential for effective fire and smoke damage restoration.
