Water Staining and Marks

Water-stain contamination, it manifests distinctly on varied substrates in laser cleaning scenarios. On porous stones, these residues form intricate ring patterns from evaporated minerals, which adhere tenaciously dependent from humidity levels. Metals, by contrast, exhibit spot-like deposits that resist initial pulses, leading to uneven removal. This contamination, it persists on glass surfaces as hazy films, influenced from prolonged exposure to hard water. The laser process yields selective ablation, yet challenges arise in crevices where the layer embeds deeply. It appears that organic residues within stains complicate detachment on ceramics, demanding adjusted fluences for efficiency. Shows particular difficulty on painted woods, where the contamination alters texture subtly.
