The key to routine maintenance of zinc alloy labels lies in gentle cleaning, avoiding extreme environments, preventing physical damage, and regularly checking their fixation and surface integrity to ensure long-lasting labeling effectiveness and metallic texture.
For daily cleaning, use a soft cotton cloth or microfiber cloth dampened with a small amount of neutral detergent (such as diluted dish soap) to gently wipe the surface to remove fingerprints, dust, or grease.
Never use cleaners containing acids, alkalis, or chlorine (such as toilet cleaner or bleach), as these may damage the electroplating layer or cause localized corrosion.
If there are stubborn stains on the label surface, soak it in clean water for a few minutes to soften the dirt, then gently wipe it. Never scrape with steel wool or a hard brush.
Environmental Protection: Keep away from moisture, high temperatures, and chemical exposure.
While zinc alloys have good weather resistance, prolonged exposure to high humidity or salt spray environments (such as coastal areas, bathrooms, and kitchens) may induce oxidation. It is recommended to choose protective labels with trivalent chromium passivation and electrophoretic coating.
Avoid installation in areas with consistently high temperatures (above 120°C) to prevent softening of the substrate or blistering of the coating, especially near machinery, lighting fixtures, or engines; ensure adequate insulation.
Keep away from strong acid and alkali vapors or oily environments (such as chemical workshops), as these chemicals may cause surface spots, discoloration, or even structural damage.
