What pH level should be avoided to prevent damage to wool carpets?

Wool carpets are particularly sensitive to pH levels, and maintaining a neutral to slightly acidic pH is crucial to prevent damage. The correct choice references a pH level that exceeds 8.5, which can lead to issues such as discoloration and degradation of the wool fibers. Wool is naturally acidic, and when it encounters products or cleaning agents with a high pH, it can weaken the fibers and alter the texture and appearance of the carpet.

Maintaining a pH level below 8.5 facilitates the longevity and integrity of wool carpets. While very high pH levels, especially those above 9, are particularly detrimental, avoiding anything above 8.5 is a key guideline in carpet care. This understanding is essential for professional carpet cleaning technicians to ensure they select appropriate cleaning solutions that will maintain the quality of wool carpets, thereby preserving their look and feel for a longer duration.
