To effectively acid wash concrete surfaces, first, prepare the area by cleaning and removing any debris. Next, mix a solution of water and muriatic acid in a plastic container. Apply the acid solution to the stained areas using a brush or sprayer, making sure to wear protective gear. Allow the acid to sit for a few minutes, then scrub the surface with a stiff brush. Rinse the area thoroughly with water to neutralize the acid. Repeat the process if necessary to achieve a clean finish. Be sure to follow safety precautions and manufacturer instructions when working with acid.
