Because these mineral bonds act like concrete, standard surface sprays rarely work. To dissolve them completely and restore that “like new” shine without scratching your fixtures, you need an acidic approach that breaks down the mineral matrix.
The Chemical Strategy: Acidic Dissolution
The secret to effortless removal is giving a mild acid enough contact time to break down the calcium and magnesium deposits.
