Aurora 33% Hydrochloric Acid is a powerful, multi-use acid designed for surface preparation, cleaning, and pH control. Commonly used for acid etching concrete, it ensures better adhesion of coatings and sealers by opening up the surface. Also effective in metal pickling, removing scale and corrosion, and as a pool pH adjuster.
The high concentration offers excellent dilution value, making it ideal for contractors and facility managers who need results without waste.
