Hydrochloric Acid 26% – 28% (290g/L – 320g/L)

– Reduces the pH in pool water, improves clarity and improves the effectiveness of chlorine.
– Cleans and etches bricks and concrete.
– Metal processing.

pH Adjustment in Swimming Pools, Brick Cleaning and Concrete Etching, Industrial processes, Mineral Processing, Metal Preparation.** Brick Cleaning and Etching >>> 1. Remove lumps of concrete with a scraper. Wet bricks thoroughly with water. 2. Mix 1 part Acid with up to 10 parts water. 3. Apply Acid solution with a broadbrush and rinse off with water once chemical reaction (frothing) has ended.** pH adjustment in Swimming Pools >>> 1. Add 100ml of Acid per 40,000L of water to lower pH by 0.1 on the pH scale i.e. 7.9 to 7.8 2. Run pool pump for at least 1 hour after adding the Acid. Retest and adjust after 8 hours running. ** REFER TO SAFETY DATA SHEET (SDS) BEFORE USE
