Hydrochloric acid
Hydrochloric acid was historically called acidum salis, muriatic acid, and spirits of salt.
A 10-percent solution of hydrochloric acid is a good cleaning agent for brickwork. Typically bricks become stained due to mold growth, formation of mineral deposits, and contamination. It is important to prepare the solution properly, as the acid cannot be directly applied to the brickwork. A solutions of 9 parts water to 1 part acid applied to a rag or sponge can be applied to the brick to scrub away any imperfections.
Pools can be cleaned with the help of detergents and scrubs, but some of the staining is not easy to remove. You can treat dark stains that adhere to the grout in between the tiles with hydrochloric acid. When using the product for pool cleaning, make sure you do not apply it directly. The same 10-percent solution mentioned previously should do the trick. Alternatively, you can follow the chemical manufacturer’s recommended mixing procedure.
Alkalinity in masonry causes problems when applying paint or sealers. It prevents the coating material from properly adhering to the surface, therefore requiring neutralizing procedures. To neutralize the alkalinity, you have to apply hydrochloric acid solution to the entire surface before applying the coat. This will help the coating material bond with the surface.
Hydrochloric Acid (also referred to as HCL) is used for lowering pH in Pool Water. Test pH weekly. The recommended range is between 7.2 and 7.6. If the pH is higher than 7.6, correct it by adding the Hydrochloric Acid as shown on the following table.
Never add Hydrochloric Acid when people are in the pool.

General Instructions
- When adding Hydrochloric Acid ensure that the product is mixed thoroughly with water remembering to always add acid to water, never add water to acid.
- Apply the mixed chemical to the surface of the pool water.
- Allow 2-3 hours mixing with the filter running before measuring pH again. Carry out minor adjustments as necessary. If unsure take a water sample to your Pool Pro Professional.
- Store in an upright and secure position in a cool, well ventilated place. Keep out of reach of children.
- Make sure you read all the instructions on the label.
- Do not allow Hydrochloric Acid to come in to contact with any other chemicals, metals, carbonates, or concentrated alkalis.
Available sizes : 4 x 5lt, 20lt, 200lt & 1000lt. Larger sizes by request.
