What type of brush is best for dusting latent prints on finished leather?

The best type of brush for dusting latent prints on finished leather is the fiberglass brush. Fiberglass brushes are specifically designed for delicate surfaces and fine details, making them ideal for collecting dust from non-porous materials like finished leather. These brushes have soft bristles that are gentle enough not to damage the surface while effectively capturing the powder and lifting the latent print.

Using a fiberglass brush minimizes the risk of smudging or damaging the prints, which can occur with stiffer brushes. This is particularly important when preserving evidence, as the quality and integrity of the print must be maintained for accurate analysis and potential forensic evaluation. Other brushes, such as metal or foam, may not provide the same level of care, and sponge brushes might not be as effective in picking up fine powder without losing the details of the print.
