Numerous techniques for revealing latent fingerprints on different surfaces have been documented in the literature. This research introduces a new, straightforward, and non-toxic powdering method for developing latent fingerprints on various substrates. The study employed lemon powder, an affordable, easy-to-use, and readily available material, to detect latent fingerprints on nine different substrates. The findings indicate that this method yields highly clear results on most surfaces.
