Scale removal is one of the more difficult matters to resolve in pool care. Ultimately, the best solution is to drain the pool and acid wash the surface, wasting both water and the life expectancy of the surface. New-and-improved Stain Drop No.2 is a specialty acid-based treatment designed to eradicate scale from surfaces. Treatments often are quick but can take up to 10 days. Stain Drop No.2 is a better alternative to the time needed to prepare the pool for a whole lot of brushing by hand, the company says.
