Soft water, with lower mineral concentrations, is less prone to staining. This difference is critical to understanding the source of the problem.
Influence of Water Temperature on Stain Formation
Water temperature plays a role in the rate at which minerals precipitate. Warmer water holds less dissolved mineral content compared to cooler water. Consequently, warmer water may deposit minerals faster on a surface. However, this is not the sole determining factor. The overall mineral content of the water is the primary factor.
Furthermore, prolonged exposure to any temperature of hard water contributes to the build-up of stains.
Correlation Between Water Hardness and Stain Formation
| Water Hardness (ppm) | Likelihood of Stain Formation |
|---|---|
| 0-50 | Low |
| 51-150 | Moderate |
| 151-300 | High |
| >300 | Very High |
This table provides a general guideline. Factors like water chemistry and granite type can influence the exact correlation.
