The best stain remover for water marks depends entirely on the surface.

The "strongest" stain remover depends heavily on the type of stain. For laundry, enzyme- and oxygen-based formulas break down complex organic messes. For hard surfaces, solvent-based or professional-strength products that cut through grease and resins are best.
For tackling tough everyday stains on fabrics, OxiClean MaxForce (for makeup and grease) and Miss Mouth's Messy Eater (for food and wine) are top-rated standalone sprays. However, simply pretreating your clothing with a high-quality liquid laundry detergent is often just as effective.
Hard water stains are generally not permanent and can be broken down with acidic cleaners like white vinegar. However, if left untreated for years, the mineral deposits can physically corrode and eat into the surface—a process called etching—which results in permanent damage.

To remove deep or set-in stains, first identify the stain type (oil, enzyme, or dye) to choose the right treatment. Always blot—never rub—the stain to prevent spreading, and apply a pre-treatment like liquid detergent or an enzyme cleaner, allowing it to sit overnight before laundering.
The best way to remove hard water stains from faucets and fixtures is to use white vinegar, which dissolves mineral buildup without damaging most finishes. Simply soak a cloth or paper towel in vinegar, wrap it around the affected area, and let it sit for 15–30 minutes.
Neither is strictly "better" overall; they excel at different types of messes. OxiClean uses oxygen-based bleach, making it superior for organic stains like blood, wine, and grass. Shout uses enzymes and surfactants, making it the top choice for breaking down grease, oil, and food-based spills.

Hotels keep glass shower doors spotless by combining strong commercial cleaning agents with routine maintenance and smart preventative coatings. Because they deal with heavy daily guest turnover, housekeeping staff rely on quick but highly effective strategies to prevent soap scum and hard water buildup.
Unlike new water damage, which appears as dark and wet patches, old water damage stains are typically yellowish or brownish. These stains may have been present for a long time, indicating that water damage occurred in the past and was never adequately addressed.
There is no single "number one" stain remover for every situation, as different formulas target different stains. However, based on extensive testing by consumer experts and dry cleaners, a few industry leaders stand out as the best for specific needs:
