Advanced Hard Water Stain Remover & Surface Protector

Hard water stains are a persistent and frustrating problem for many homeowners, particularly on kitchen and bathroom appliances like stainless steel sinks and fridges. While basic cleaning agents exist, there's a demand for a more effective solution. A specialized product that not only aggressively removes tough, built-up hard water stains but also applies a durable, easy-to-use preventative coating (e.g., hydrophobic, anti-spotting) would significantly reduce the frequency of deep cleaning and help maintain the aesthetic appeal of appliances.
