What is Hydrochloric Acid 30% used for?

30% hydrochloric acid is used in a variety of sectors for specific chemical and industrial applications. It plays a key role in removing cement residue and mortar residue from bricks and tiles after construction, dissolving limescale and cement film without damaging the underlying material. It is also used for rust removal and metalworking, such as derusting, descaling, and etching, and for surface preparation prior to coating or plating processes.

Within industrial processes, 30% hydrochloric acid is also used for pH regulation, including in water and wastewater treatment. In laboratories and chemical environments, it is a common substance for analytical and synthetic applications, including pH adjustments and titrations. It is also used for technical cleaning, for example, in removing inorganic contamination from concrete, stone, and metal surfaces. Finally, hydrochloric acid is used in the textile and leatherworking industries, where it is incorporated into specific processing and finishing processes.

Storage and use

Store 30% hydrochloric acid in suitable plastic or glass containers in a cool, dry place (15-25°C). Hydrochloric acid is volatile and can release hydrogen chloride vapors. Ensure good ventilation in the storage area.

Use only in suitable, professional environments. Always wear protective gloves, safety glasses, and a face mask. Work in a well-ventilated area to avoid inhaling vapors. Rinse all treated surfaces thoroughly with water. Never mix with bleach, ammonia, or other chemicals, as this can produce highly toxic fumes. Keep away from metals and strongly alkaline materials.
