Which method is typically the first step in removing soot residue?

The dry removal method is typically the first step in removing soot residue because it is designed to lift and remove dry, loose particles without introducing moisture. Soot, being a fine and dry material resulting from incomplete combustion, can easily be loosened from surfaces through mechanical means.

In this method, tools such as dry sponges or specialized brushes are often utilized to pick up the soot and debris. This approach is crucial because applying moisture or cleaning solutions too early can cause the soot to smear or penetrate deeper into the fibers or materials being cleaned, complicating the cleanup process.

By starting with a dry removal technique, technicians can effectively collect the soot while minimizing further damage to the underlying surfaces or fabrics. It sets a solid foundation for any additional cleaning processes that may follow, ensuring that the cleaning is both effective and thorough.
