Final answer:
The first step in restoring a smoke-damaged fabric is to remove any loose soot particles.
Step-by-step explanation:
The first step in restoring a smoke-damaged fabric is to remove any loose soot particles. This can be done by gently vacuuming the fabric with a brush attachment or using a dry sponge to blot away the soot. It is important to avoid rubbing the fabric as this can push the particles deeper into the fibers. Once the loose soot has been removed, the fabric can then be treated with an appropriate cleaning agent or taken to a professional cleaner.
