Remove years of stubborn stains, algae buildup, and discoloration. Professional acid washing restores your pool's appearance and gives it a fresh, clean look.
Over time, even well-maintained pools develop stubborn stains that regular brushing and chemicals can't remove. Algae, mineral deposits, calcium buildup, and organic staining penetrate the plaster surface and dull your pool's appearance.
An acid wash is a deep cleaning process that removes these embedded stains by treating the drained pool surface with a diluted acid solution.
