To ensure the longevity of wool carpets, which pH level is ideal?

Wool carpets are particularly sensitive to pH levels, and maintaining the right balance is crucial for their longevity and appearance. The ideal pH level for cleaning wool carpets falls between 4.5 and 8.5. This range is beneficial because it is slightly acidic to neutral, which helps to preserve the natural fibers and prevent damage that can arise from more alkaline or acidic conditions.

When the pH is too low (highly acidic) or too high (highly alkaline), it can lead to issues such as color fading, weakening of the fibers, or even shrinkage. Keeping the pH in this optimal range helps to maintain the structural integrity of the wool and ensures that any cleaning agents used do not adversely affect the carpet's quality or appearance.

In contrast, options that suggest a pH outside the range of 4.5 to 8.5, whether notably acidic or alkaline, could compromise the wool fibers, leading to deterioration and reduced lifespan of the carpet. Thus, adhering to this pH level is essential for proper care and maintenance of wool carpets.
