Mineral Staining

Mineral-stain contamination, it manifests as inorganic coatings from environmental deposition. These stains form unique patterns, dependent from regional humidity and mineral sources, creating patchy, crystalline layers on surfaces. On metals, the contamination adheres tenaciously, which resists laser ablation due to strong bonding. Stone substrates exhibit looser attachment, that yields easier removal. Challenges arise in selective cleaning, where the process demands precise energy control to avoid substrate damage. It appears that formation varies with exposure, leading to differential behaviors across materials.
