Dye Stains may be applied to latent fingerprints on nonporous surfaces (plastics, glass, metal, etc.) which have been initially processed with Cyanoacrylate Fuming. The Dye Stain may be applied with a spray bottle or wash bottle, followed with a rinse solution. The resulting fluorescent latent fingerprints may then be visualized with a Forensic Light Source and Forensic Goggles. Always wear personal protection equipment such as coveralls, gloves, respirator, and eye protection when working with chemicals.
